Renault Clio Airbag Light Fix

[@Stheno490BC]

You are worth your weight in gold. My Kangoo had this fault, which was the only reason it failed the MOT. I took it to a local garage who told me that a fault on the vans engine management system meant their diagnostic equipment would not talk to the vehicles system which meant my next step was the dealers & a whole bunch of money & stress. So I decided to check out Y.T. & found your video, as soon as I wiggled the connection you indicate the fault disappeared. I can't thank you enough. :)

[@DomRosser]

Thanks so much, spent over £100 at garages and have got nowhere with it. 10 mins and it's done for free!

[@manliovitiello9614]

I used 2 resistors (3,9 Ohm, 5 W) to short-circuit the Yellow plug behind the wheel. It worked 🤟

[@peugeotCitroen2CV]

It may indeed remove the warning light although im not 100% sure it will ensure a functional airbag in the event of a crash. However it probably resulted in an economic saving which is in itself something that may satisfy the definition of an effective repair on an older car.

[@theedscape8002]

Thanks a mil for this helpful video. My lights came on about 3 weeks ago and have been doing their on/off thing ever since. My 2006 Mk2 Clio was having its 2 yearly Irish NCT test on Friday and the guy failed it on this point. I asked him why he failed it when there was no passenger seat airbag fitted. He couldn't answer. Of course he couldn't, he wasn't a mechanic, just a poxy test jockey. Being a mechanic of 25 years I gave a good account of myself before leaving the centre. On Saturday morning I reached under the passenger seat and jiggled the loom. Bingo, the lights haven't surfaced since. I returned today (Monday) and had my visual retest done in 2 minutes, got my cert and if the lights come back on they can fuck themselves for another 2 years. Once again, many thanks.

[@peugeotCitroen2CV]

Great to hear you got through the test, i did not know the NCT was every other year. As for the light coming on even if there is no airbag mounted in the passenger seat, the pretensioner for the passenger seatbelt is found on all models of clio and the wires can get loose for it, they all run through the same system as the airbags with the pretensioners detonating around the same time.

[@theedscape8002]

Yeah the NCT is every 2 years from 4 years old to 10 years old. Then it's every year.

[@Mixbag]

@@peugeotCitroen2CV i replaced my drivers window regulator because old one snapped. It now works but now the passenger window has stopped working. There is no relay clicking too. But drivers window still works i tried passenger side switch snd still no working.

[@peugeotCitroen2CV]

@@Mixbag Has it stopped as a direct result of the work done on the driver's side, or phrased another way has the fault with the passenger side window only presented itself following the completion of the work on the driver's side door? I have a separate video on the Clio electric windows have a look through the Clio playlist on this channel. Although its possible that something may have been disturbed on the connector to stop the passenger side window from working. As the other video will show providing power directly to the motor can be used to identify if the motor is faulty, or if it's the wiring going to the motor.

[@Sandeep2463]

Hi, Thankyou for the video. My renault clio had the same problem. The car was rejected in the vehicle inspection due to it. Basically it was due to the loose wires under the driver seat so when I pushed the wire inside that white plastic socket, the air bag light went off. Do you know if this is enough to pass the inspection or the symbol needs to be removed by the machine which is used to check the electrical system (the ones which they use in inspection centers) of the car?

[@peugeotCitroen2CV]

Conductive yep, but thats good because when the connection is rusty or dirty it isnt conductive, the wd40 restores that conductivity, you could blow it away with an airline if your worried about the pins shorting through the wd40, nonethless thanks for the comment, and good luck with the soldering

[@peugeotCitroen2CV]

The purpose of the plug is to connect the wires for the pretensioner and seat airbag up with the airbag wiring loom in the car, because of how cars are made plugs are used because this is the quickest way on the assembly line to make the connection. The plug does nothing more than connect a series of wires together, so it can be removed and replaced with soldered connections if it is giving trouble. The soldered connection (if soldered well) is much more reliable than the plugs.

[@gavinflintoft6084]

Another Clio airbag fixed!! Many thanks buddy!

[@peugeotCitroen2CV]

Glad to help!

[@peugeotCitroen2CV]

Thanks for your comment, that is great news, its also good to hear the process is the same for the kangoo

[@mikemckay9554]

great video , i would just like to add ,if your clio has the service and airbag light on ,as well as the indicators stopped cancelling and you notice a bit of a clik coming from the steering wheel column when you turn the wheel ,your problems could be the airbag thingy in the centre of the stalk column has broken and needs replacing

[@rhinotrikes8004]

Hi Very usefull video bought a 51 plate 1.5 DCi for my Son, airbag and service light on. Didn't see this video and followed forum advice badly. I didn't realise the grey plugs under the seat on this clio had allready been cut and soldered cut the black one from under drivers seat and soldered that one. Is this just a connector (looks very complicated way to join three wires) or have I cut out a vital component. (It's the other connector you show in the video) car has seat airbags x2 Thx

[@chentaihai]

That's very clear and problem-solving. Your comments are very much appreciated! :-)

[@peugeotCitroen2CV]

It is a bit confuising, have you tried a different diagnostics machine, what sort are you using right now? It could be the instrument cluster/dash, is your car one of the newer shape clios or the last of the mk2's? Try renault forums find out if you can plug an instrument cluster in from a scrapyard car and if it affects the mileage, they are easy to change over once the dash top is off.

[@rhinotrikes8004]

Thx for reply it is the plug you pull down at 1.02 but is connected to seat airbags in this car all wires except for the duplicate of this one on the passenger side have been clipped and soldered. Getting ecu interrogated tomorrow. will post the result. Thanks again.

[@peugeotCitroen2CV]

Any more than just short? Check the wiring under the seat, is there evidence of any previous attempt to repair this, especially wires not insulated properly.

[@peugeotCitroen2CV]

Its definatley not near the gearstick or in the cabin, its either around the bellhousing in the engine bay, but i remember from other renaults that its in round behind the passenger side wheel, go to where the driveshaft meets the gearbox, you will see the switch in there, i think its a fairly big socket 24mm.

[@peugeotCitroen2CV]

Your welcome glad to be of help. As for the lights, do you mean the reverse light wont come on or all the rear lights? Things to check are; bulbs, fuses, connectors and earthing points associated with the rear lights. But the reverse switch is located on the gearbox, i cant remember 100% but its on the bellhousing somewhere, under the air filter box on the 16v engine. Im not sure right now, if you cant find it let me know ill look at my car, or a manual and see what it says.

[@peugeotCitroen2CV]

Possibly get an airbag module/ecu from a car that does not have seat airbags, but that may pose a problem as the cars main ECU or UCH (Unite Centrale Habitacle, or ecu for non engine stuff) may not work with an ecu from a car of different specs, its worth trying renault forums to see if its possible to put an airbag module from a car with no seat airbags into a car that had seat airbags. Unless, is the seats you put in airbag equipped seats that have broken sockets by any chance?

[@peugeotCitroen2CV]

Sorry i dont know what it means, normally google shows up what they are but its saying nothing for that code, does the machine not give a description below the code? What issues are you experiencing with the car?

[@m1tnick]

Hi. The reverse light won't come on when I put the reverse gear. Sometimes it does, others it doesn't. So I believe it is related with that reverse switch you talked. I tried to look under the gear level, but there is a with plastic around it. It does not seem trivial to take it off :( Can you please let me know where I can find that switch? My car as a 1.5 dci engine. Thanks again for your help!

[@peugeotCitroen2CV]

I agree, i initially fixed my 406's airbag light using scott locks and they are terrible, 3 months later they failed bringing the airbag light back on, and i had also used them for parking sensors and the metal connector inside them actually rusted. Solder with heat shrink tubing is the most reliable way to join wires.

[@dimitrispapas9788]

Is there a chance that this could be caused by blown airbag fuse?I mean the service and airbag lights.Because we tried the trick with the plug under the passenger seat(in fact an electrician at a Renault dealership did it)but the lights didn't go off.At another Renault dealership told us that all 4 airbags are failed and should be replaced whilst at a couple of garages told us that the clockspring(behind the steering wheel)is worn out and we need to replace it.

[@peugeotCitroen2CV]

hi one plug is for the seatbelt pretensioner (grey) and one is for the airbag (black), on the more basic clios they only have pretensioners. Are you talking about the connector which appears at 1:02? Any chance you could get the car plugged into a diagnostics machine to see what fault code it brings up? Or alternativley send me a private message and a picture of the wiring under the seat so that i can see whats going on.

[@peugeotCitroen2CV]

There are very few car companies who do it differently, its quicker on the production line to plug in the seat connector than to start soldering them in.

[@peugeotCitroen2CV]

The meganes have problems with the wires under the seat aswell, i cant remember exactly what the colours are but its the plug for the seatbelt pretensioner gets loose and causes the problem. Its most likley the issus.

[@ivanm.3522]

Cannibalizing the car's foam to clean the connector is just a sublime revenge over customers who never clean their cars exposing you to cholera. Thank you! best tip ever. BTW I hope I will fix the airbag too.

[@peugeotCitroen2CV]

One way of looking at it haha This particular car was a freebie, the previous owner left it in this state. Best of luck with the repair

[@ivanm.3522]

@@peugeotCitroen2CV in the meenwhile I got no luck with the connectors. This car was flooded for a while. I fear the problem belongs to cable harnesses.

[@peugeotCitroen2CV]

@@ivanm.3522 Next thing i would advise is get it plugged into diagnostic equipment see what it shows as the fault. If the car was flooded the ECU might have got the brunt of the liquid damage.

[@ivanm.3522]

@@peugeotCitroen2CV Thank you so much for your help. I have some cheap diagnostic cables here. None of them seem working. Do you have any advice for a good, (possibly cheap) diagnostic cable/equipment?

[@peugeotCitroen2CV]

@@ivanm.3522 For these older Renaults they used a thing called CLIP there are clone machines from China available on ebay. I bought one about 10 years ago and it works fine. Although now have a tablet that uses Launch. These are not the cheapest options but in general to get diagnostic equipment that does airbags or abs systems basically above and beyond the engine then they tend to be more expensive. The engine systems are much more standardised hence why diagnostic tools that read engine codes can be bought much cheaper. If its for a one off job like this finding a mechanic or someone that has the equipment might be a better option.

[@peugeotCitroen2CV]

if the problem is fixed properly the car will turn the light off itself, does the diagnostics equipment point towards any fault? What sort of machine are they using? Take it to a proper auto electrician with a decent fault code reader or someone with a renault clip diagnostics machine to get a proper reading of what is causing the fault.

[@peugeotCitroen2CV]

By the way you described it your car has a few plugs under the seat, do you have side airbags in the seat? If the plugs are loose (you cant tell exactly what one without a diagnostics machine) then cut one pair of wires that are parallel to eachother in the plug ie the one going in and one going out, do one pair at a time for the affected plug.

[@hujimwa]

Yea good video helped thanks. Need my crash data erased but thats like30-40 quid with postage cheaper and easier to get another ecu then? Got new seat so i believe its a straight swap now?

[@Mmmmgrolsch]

Ah right cheers, no it's not had a bump. On diagnostic tool looking at the actual values I can see power to the passenger side and not to the drivers side, I'll try checking the connectors and the wire then just replace it? Reckon a 2nd hand one will be ok to put on?

[@peugeotCitroen2CV]

Sometimes second hand ones will work ok as long as the car they come from has not been hit, but renault forums are definatley worth a visit to check this is ok

[@bfg69bug]

Hi, in the first part of the video you had 2 faults - the pretensioner and computer supply voltage. You soldered the cables, which fixed the pretensioner, but how about the 'computer supply voltage' issue ?

[@peugeotCitroen2CV]

A historic fault code stored because at one time the battery was low. Quite common to get a sleuth of fault codes on cars that have sat, the trick is usually to clear them and see what returns there and then

[@palmsam159]

I've had this problem twice, each time all i did was sprayed the connectors under both seat with contact cleaner, (can pick up cheap from maplins). both times this has solved my issue, it just gets dusty down there and gets in the plugs. blow into them and spray this. works for me!:) ps i have a mk 2...

[@peugeotCitroen2CV]

Good stuff.

[@peugeotCitroen2CV]

I see, try renault forums to see if they know of this code, but a different scan tool perhaps a high end one like the snap on if you know someone with one might be able to give a definition for the code. Sorry im not too familiar with different code readers. Although have you tried fixing the wires under the seat, and checking the airbag ECU because the light will go out if the problem is fixed

[@peugeotCitroen2CV]

Do you mean the passenger airbag deactivation light, or the general airbag fault light? an airbag light (which normally appears with the SERV light) means there is a fault with the airbag system, it might not go off in an accident. Have you checked the passenger airbag deactivation switch is still pointing to the on position

[@alexjb1989]

Hi buddy, great video. Do you know what I should do? I hit a curb and the Drivers seat airbag went off. I then replaced the drivers seat and a the ecu with ones from a scrapyard clio (it had not had the airbags go off) but the light Service light and the airbag light is still on the dash. The garage put the seat in, but don't know why the lights wont go out. Any help you could offer would be fantastic. My MOT is soon and I know it wont pass!

[@tommymac3112]

Alright mate, great video, my clio 54 1.4 dynamique does have passenger seat airbags if i cut the wires and solder them together will this set off the airbags when i connect the battery back up? Been told by the garage where it failed the MOT that the fault is either the airbag ecu or the wiring under the seat. Cheers

[@spicedave]

51 Reg 1.2 Clio Dynamique. I also have the problem with the air bag and Serv lights staying on. I've done the following: Replaced the air bag ECU, replaced the spin ring on the steering column. Someone who owned the car before me has had a go at soldering the wires beneath the passenger and drivers seats. I've resoldered these but I don't know if they were right to start with. Lights still on. Could you tell me what coloured wires go to what coloured wires. Much appreciated of any help

[@peugeotCitroen2CV]

Thanks that would be the clock spring you are describing. I did have that problem once on the 406 when i bought a used indicator stalk (ie com2000), on it the indicator stalk, wiper stalk and the clock spring are all one part. They can also break when the car has had the steering rack disconnected if the joint isnt put back on straight the wheel can be slightly off to one side so turning it on full lock can snap the clock spring.

[@peugeotCitroen2CV]

If soldering the wires for the pretensioner doesnt solve it, then yes try the black plug aswell. Although i normally find the grey plug to give trouble first, the black one has cable ties on either side to hold the wires tight to the plug, the grey one does not and therefore the wires can get loose easier.

[@alexjb1989]

Thank you for the reply. Is this something that I should just replace myself (is it easy) or does it make more sense to take it to a garage with a CLIP machine first? Thanks again

[@Strawberry_amelia]

hi mate i had changed my seats on the clio and i have no air bag sockeg for the cable to be plugged in so the air bag light is always on. any suggstions to clear the air bag light?

[@Mmmmgrolsch]

Forgot to say its the Drivers front airbag 'igniter' short circuit. I'll have a look on Renault forums. Don't suppose you know where the igniter will be do you normally? I work on cars for a living but dont have experience with airbags

[@secretlol100]

Hi I have a Clio 8v 2002 with Seat airbags. Removed the grey connector and soldered the wires together - Serv and airbag light still showing regardless. No chance of drinks being spilt as I've had it since new and never spilt anything. Just to confirm - which colour wires do you solder. Is it brown to brown and orange to blue?

[@peugeotCitroen2CV]

Your in NI, what part so am i, the test centres are indeed quite strict. If your after decent auto electricians try hobson electronics they are very good. Its possible they have wired up the thing wrong, and their diagnostic machine may not work with the clios airbag system.

[@Lippy8555]

There has been a previous attempt on the passenger side, although the computer says it's the driver side. It was a general purpose fault code reader. I've soldiered the black connector wires, I'm going to do the grey connector this weekend. Any clues or help is appreciated and thanks for your reply.

[@peugeotCitroen2CV]

exceptionally well looked after by the previous owner :)

[@ROB010867]

hi forgot to ask...my clio is 2004 model and has seat airbags fitted so does the black plug you mention have to be cut??

[@JonnyCopeyNI]

Thanks very much for getting back to me I'll try that side tomorrow and let you know how I got on :)

[@peugeotCitroen2CV]

On the grey plug you mention one side should be a brown, and a blue wire. The other side should be a pink, and an orange wire. (under the passenger seat not drivers seat) Also note that i knew the problem was coming from here because i had connected the car up to a diagnostic computer before cutting any wires. @0:40 it shows up the fault "passengers side front buckle pretensioner circuit" ie a loose connection which i knew was dealt with by the grey plug.

[@peugeotCitroen2CV]

Is there a difference in the two wheels? You would need to check if the connections on the back are the same, but even then I'm not sure if the airbag modules are the same or if they are compatible with each other since I've never been in one of the larger engined clios. Its best to check renault forums first to see if this can be done

[@peugeotCitroen2CV]

The airbag light comes on for a variety of reasons and in the video i only look at one reason, although i find it to be the most common reason. The grey and black plugs are separate, grey is for the seatbelt pretensioner, black is for the seat airbag in the video i cut the wires going into the grey plug on the passenger seat and soldered each pair of wires together @1:16 you can see me cutting the wires; the pink wire is connected to the brown. and the orange wire is connected to the blue.

[@markyboyc24]

Hi so see the grey one on one end there is just Brown and blue but on the other there is a few coming out?? And should I do the black connection box too?

[@peugeotCitroen2CV]

The drinks holder bit pops out of place, i never cut it out. If you then see the airbag ecu covered in any spilt drink, then you can take the rest of the trim surrounding the area out of the way, which is also held in place with a few clips, and having the drinks holder out of the way makes it easier to get the centre console out.

[@peugeotCitroen2CV]

The impact sensor on the car, have you changed it? There would be a front impact sensor somewhere in the front bumper and one in the B pillar near where the seatbelt reel is If they haven't been replaced then they are still sending crash data to the ecu, a diagnostics machine will say exactly what sensor is detecting an impact

[@peugeotCitroen2CV]

The impact sensors once they sense an impact they need to be changed, my cousin tried to get second hand sensors from the scrap yard but none worked new ones for the dealer were the only solution unfortunately. Did you replace the ecu with a new or used one, its possible the donor car has crash data in it, but you can send the ecu away to have its crash data erased some companies do that service, although if you can find one in a scrapyard car that hasnt been hit its usually cheaper.

[@peugeotCitroen2CV]

Other than the airbag ecu the only other electrical thing in that region is the obd socket (found by lifing out the ash tray). The immobiliser reciever is around the key barrel, what condition is the key itself in?

[@Dayglowvista]

Hello, I've got a Clio DCi 51 plate. Airbag and serv light on. Had my MOT today and they plugged it into a diagnostic tool (charged me £48 for that alone) and told me that there's a fault with both driver and passenger side airbags, but they said this was likely due to a faulty ECU. I'm guessing I may have a similar problem to what you've got in the second half of your video, but I've never split any drinks down there. Any suggestions before I start ripping the console off? Cheers.

[@chentaihai]

Hi Peugeot. Thanks for the video. My car has got airbag light on constantly and failed MOT test recently. In my case, my car is a bit diff. to your demonstration one. It has the seat airbag, that means the red plug has its own use. That leads me to two questions: (1) Not sure which plug (red for seat airbag, and grey for seatbelt pretensioner) has caused the light on. (2) In your case, you cut and soldered the parallel wires. But does it mean the pretensioner would fail in case of car crash?

[@trenery44]

Got same error on 2005 1.2 16v. Just got the car and they had taped over the warning lights so I didn't notice. (long story but cant take it back) Have already soldered all under seat wires and changed the ECU. I haven't done the crash sensors on the sill and one of the errors was 179 "offside front sensor circuit no signal". Also got fault code 194 Replace ECU after impact - locked following impact" is this the Airbag Generating this fault code? It had minor front end damage a few years ago.

[@peugeotCitroen2CV]

Good to hear you got it sorted.

[@peugeotCitroen2CV]

I appear to have ripped a bit of the old carpet and used it to clean the plug. The car was for spares and the old carpet was mouldy, and ripped in other places.

[@peugeotCitroen2CV]

Hi, i always remove the battery and let the car sit for 30 minutes before working on the airbag system.

[@peugeotCitroen2CV]

The time my ecu was faulty it came up as a fault code no communication with the airbag ecu or something to that effect. I picked up a replacement ecu in the scrapyard for £10 but the car was there because the engine had blown it wasnt involved in a crash. What sort of diagnostics machine was used, was it a renault clip one or universal one? Can you lift up the cup holder to see if there is any moisture in there, the previous owner may have dropped a drink?

[@peugeotCitroen2CV]

Have you tried to rewire it yourself or has there been any attempt by a previous owner to rewire it ie under the seat? Did you use a general purpose fault code reader or the renault one?

I have no idea what happened to this car before i got it, but it looked like the owner lived in the car, old food wrappers, old sweet packets with sweets lying about the place even spilt fizzy drink, then it was left sitting for over a year which brought the mould and dampness, it looks disgusting in the video it was 10 times worse actually smelling the inside.

[@peugeotCitroen2CV]

When you say meter states do you mean diagnostics machine? If it has specified the passenger seat then its most likely the black plug as i have shown in this video, cut one pair of wires and solder one pair at a time so they dont get mixed around

[@Mmmmgrolsch]

I'm trying to sort my ladys car out, fault code says "FC003 Driver front Airbag short Circuit" I'm guessing this is referring to the steering wheel airbag?

[@peugeotCitroen2CV]

That sounds like the steering wheel airbag, on the clio the airbag and igniter are one unit, the steering wheel centre comes out and that part is what should be replaced. Has the car been bumped into anything to trigger the airbag?

[@ShareholderMr]

Wat equipment would I need to do this? If I don't have it then wouldn't it just be cheaper to go to a garage?

[@peugeotCitroen2CV]

The diagnostic equipment helps to identify which plug is causing the fault, but in most cases if I'm fixing an airbag light for someone i just do both plugs under the passenger and drivers seat without using the diagnostic stuff. It takes a bit more time doing them all, but after it you can rule out a bad connection. When i cut and soldered the parallel wires i just made the wires connect again (the plugs go faulty and stop the wires from connecting right), thus in a crash it should work

[@peugeotCitroen2CV]

Not many people have these i accept that, however it is possible to fix the airbag light without the fault code reader. the wires under the seat or ecu if fixed as shown in the video will get rid of the light, i just show the computer screenshots to show what is going on. In them cases you can get rid of the light without the computer. But if they don't fix it, its probably cheaper getting it hooked up to the diagnostics machine to find out whats wrong. I only got the lend of this machine.

[@itztierney]

@peugeotCitroen2CV u see the plug for the seat air bags i broke the red bit on it can that ,make the air bag light and serv light come on. Thanks

[@peugeotCitroen2CV]

It depends on the fault code reader, a proper renault clip reader or a cloned one off ebay can read the airbag module, as can high end diagnostics machines, cheaper diagnostics machines cant communicate with the clios airbag system. Nonetheless check the wires under the seat, if that doesnt work try somewhere with a high end fault code reader that can read airbag ecu's and see what it says. There will definitely be a fault code if its putting the light on.

[@peugeotCitroen2CV]

There is a clamp that holds the battery in place, on the clio its just a bit of cast aluminium shaped so it grabs the lower edge of the battery, and is held in place with a bolt. You could get one out of a car in a scrapyard. Or alternatively try a DIY approach, get two threaded bars, bend one end so they catch on something below where the battery sits, put them on either side of the battery and get a flat bit of metal to bolt onto the two bars holding the battery down.

[@peugeotCitroen2CV]

The probelm with putting another ECU into the car is that the impact sensor that detected the crash if it hasnt been replaced will still be on even with another ecu, i would plug the car into a diagnostic machine first to find out what impact sensor has been triggered, then replace the sensor, and whatever airbag has went. With the parts changed see if the airbag light goes out, if it doesn't then use the diagnostic machine to clear the crash data.

[@JonnyCopeyNI]

Hi I cut and joined the wires under the passanger seat and the light didn't go of, I seen the same connector under the drivers seat, could that one give the same problem ?

[@peugeotCitroen2CV]

It was a car a friend gave me for doing some work on another car, this car had sat outside his house for a year, and i cleaned most of the rubbish out, but there still was a lot of mould and debris left. The smell was awful. The car was only good for spare parts. My car is the one you see at 1:10-1:15 its two years older but a lot cleaner.

[@peugeotCitroen2CV]

The radio code comes in a card found with the books that come with the car, unfortunately as the clio is an older car and likely to have had many previous owners the books and card can go missing, as with the code. I think there are sites on the internet that can retrieve a missing code its worth a google to find out, otherwise car audio specialists normally offer a radio decoding service

At 1:31 in the video the wires are soldered together showing the colours, its orange to blue, pink to brown. Although thats just for the pretensioner under the passenger seat, if your unsure about any of the other wires have a look under the seat of another clio to see the colour combination. I just cant remember off the top of my head what colours go where. Any confusion or problems feel free to send a Private message.

It sounds like it, although im not 100% sure, try the renault forums with that specific code number just to be sure of what it is.

Hi. I spilt red bull in the cup holder and now the ecu is water damaged and the car will not tart. The ignition turns and the immobiliser light flashes. It happened every since I spilt the drink.

Hi there peugeotcitroen2cv, I am having similar problem with my 2003 renault megane. the airbag light and a "service" light comes on when car is running. do you reckon it is similar fault to that in first part of video I am certain that no liquids were spilled into the cup holders (i dont eat or drink in car) any help would be really useful as MOT is up in january

Iv got the same problem on mine, it looks as though someone has alredy done this to the pasinger side but not the drivers iv inspected the ecu and it looks to be okay should i do it to the drivers side and see it that works ?

Hi I need a new Airbag ECU for my clio. Looking on EBAY there are lots of different ones with different numbers does it matter which one I buy or will they all work?

[@markyboyc24]

Ok so I should take it and get the diagnosis 1st so I know what side?

[@stephencox2562]

Hi ,nice video .Just wondering which wires to connect on the drivers side, as there are more than the passengers side, i think ?. More than one orange . Which colour goes with which?

[@peugeotCitroen2CV]

The best thing to do is remove one pair of wires from the connector at a time and solder those together. Ie one wire from the male connector and its corresponding one from the female connector. The airbag wires are orange, possibly ones for the seat airbag (depending on specification) and another for the pretensioner which i think they came with as standard.

Hi Peugeot,citeron2cv, thanks very much for replying. It was and is a bunch of strange electronic problem. Managed to find fault, causing strange lights situation, it was a bad earth to one head light. Ever since I got this car(47000,only)it was serviced and mot last February. I hate to accuse the garage as he's my dad's mechanic, if u get me.but when I put the clio in for service it had absolutely no problem. I wonder if they knocked something or...well I just don't know. When I try to squirt front screen with washer it comes out the back screen washer, and when I squirt back it still comes from back, sometimes it does as asked but rarely. Also the interior light has stopped working and the horn. Also have this airbag service lights, which people on here say is common. I've done their recommendations under passenger seat, no joy. It's a lovely tidy little car with a great engine. I'd hate to lose it cos I don't know what I'm doing. Any advice will be gratefully received. Thank you,Jay

Hi Jay It may be worth looking into the wiring to see if perhaps someone has bodged a repair in the past casuing the washers to work in that manner. Check that the front wiper motor works if you supply voltage directly to it, then work back from there. The interior light, has the bulb went faulty? As for the horn that could be the horn itself or the contacts in the steering wheel For the airbag plug the car into a diagnostic machine to see exactly what it says is wrong, the wires under the seats is a quick fix that works most times but there are a number of other reasons why the light would come on and plugging a computer in to read the codes tages the guessing away.

@@peugeotCitroen2CV thank you,I really appreciate your time to reply. Sun is out so I'm going to follow your advice. Such a strange problem. Cars only done 47000miles. Thanks again

[@thmsmrrtt]

My airbag light and service light only comes on when it is cold. If it is warm then it won't come on. Also if it's cold and it comes on, drive around a bit then restart it won't come back on. Does this help find out which is the cause of the problem, under the seat or the airbag ecu?

[@MegaHamstar]

okay thanks, but we have trying to get contact with the car, but the contact stick do not have enough power to answer back, what to do ?

[@peugeotCitroen2CV]

Did this solve the problem?

[@MultiSamuel95]

I know this is somewhat a stupid question, but, what device do you use in order to know what's wrong with your Clio?
