How to fix Electronic Fault on Renault Megane

a guide on how to repair "electronic fault" on your renault megane, this fault is very common and can cause your car to do all sorts of crazy things while your driving, locking and unlocking the doors, setting the hazard lights off and worst case cutting out and refusing to re-start. watch this for a few minuites and you should be up and running in no time (provided there are no deeper issues)

[@jacquesheynes5073]

Hi Paul I was in dire straights as I received the "Steering Locked", Steering not locked message today, I drive a Renault Megane Dynamic 2 and was fearing the worst. The last time I had this problem I had to fork our thousands. After watching your video i decided to give it a go, and without even needing to take my unit out, i basically just unplugged and plugged back in a few of the plugs on my fuse-box and magically the error disappeared and my car started again! Thank you so much for sharing this with us. Renault driver all over the world gets screwed on service and price daily and I thank you for being the difference.

[@cristianvelazquez8392]

Has it giving you anymore problems? Was it a automatic transmission?

[@train.sleep.eat.repeat5278]

Your a legend! I tried this ,had an electrical fault.. cleaned all the battery terminals and took out the fuse box. Opened to up and had water on the board. Used electrical sprayed and placed in a towel and on the radiator.. placed back in and hey presto. Cheers dude!

[@lyndseyfrost1852]

Thanks a lot mate worked a treat! Went through a puddle and car cut out saying electrical fault, followed exactly what you did and started straight away.

[@1soccerdanny]

Just followed your instructions for my wife's Megane. She lost all dashboard on her way to work and the STOP light came on. Watched your video did as you advised and all is well again!! THANK YOU.

[@mrtexpert1404]

Glad the video helped you out!

[@mrkooks]

I just had this error.. the car just stoped while I was driving and the "Eletronic Fault" message poped up.. i took all the fused box out .. cleaned the box.. cleaned the connectors, made sure that the box fuses were ok.. and nothing, the car still did not want to start.. then i moved to the battery fuses and with a electric tester found out that one of the 30A fuses was burned.. In my case some of the car electronics were working ok ( radio, windows, alarm, etc ).. but the car did not started because of the Electronic Fault message, with a cable i jumped the fuse and move the car to my garage mean while i buy the fuse at the local shop.. Thanks for this video, it was a great guide.

[@zaihussain8811]

Was going to scrap the Renault megane until I saw this video!! :) am very grateful for this...thanks.. Had Same issue fuse box full of water!! Try to Clean&Dry fuse box but no luck!?! So I guessed the box was totally knackered!! Went and got another fuse box from the local scrapyard £20v(make sure serial code is same as your old fuse box) cleaned it up and fitted new fuse box in hey bristo!! the megane fired up!! Great Video... 5 stars..:)

Hey! My Cabrio broke down last night and I towed it home and opened fuse box on my own after watching this video and I just paid 60 bucks for tools that will help me forever and issue resolved so far!! Thanks billions!

[@LeShiznit]

Thanks for the upload! Have had this problem for about three years but I just disconnect/reconnect the battery and then it works fine, haven't had the problem for a while now but am quite sure I will come back one day and i will have to clean the fuse box. Thanks again!

[@rocker666uk]

Great vid , in a nutshell , followed all the instructions , renault is now up and running, saved ££££££'s , thank you :-) .

[@MrBesty117]

Many thanks saved a ton as wife drove through large water puddle with the small headlight cover missing and soaked the fuses. Car did not stop there thankfully but when she got home I found it wont start later that day.Seen your video Sorted now!THANKS

[@36euphoria]

Wicked, thank you. Had this problem on and off for weeks and it was when you said about steering not locked I thought bingo. Next is to sort the seals on the roof myself

[@troels222]

Hi Paul, Had all this electronic errors coming random on my display. Further more, the cruise control did nok work. Tried your trick, but it did not help. Went to a mechanical auto engineer and he read out 7 different errors on his OBD2 computer. - But he knew the errors from earlier repair of a Scénic, the fault is in the unit sitting on the shaft of the steering wheel, (under the airbag) where all the switches for cruise control, horn, and much more are located. Since I have half a year warranty on this car I just bought, he will change the whole unit - not trying any repair. Hope that it will solve the problem. Hope that this info can help others where cleaning the relay board and plugs don't help. kind regards from Denmark

[@duanemaartens3788]

[@SevenBeatsmusic]

I had to come back to thank you my man! I had like million errors all about electronic. There was lots of water and corrosion between the board and connectors. Followed your steps (I just used some kind of spray for cleaning electronic boards instead of WD40) and fixed it in 20 minutes. Everything works perfect now. Thank you

Well done Paul and thanks!

[@ToriTori-hd4zz]

Morning Paul Thank you for the reply. So far my car has been diagnosed as a cam belt issue. They've taken rockacover off and the belt is off. Not sure if it's snapped or just come away. The chaps at work haven't had time to do anymore than that at moment. I asked if it's worth putting a new belt on it to see if it starts, but they said in their opinion it's probably damaged the valves and pistons and engine will be buggered. I looked on Internet and can source a second hand engine from brakers yard for about £230 including delivery. Just got to make that decision if it's worth spending about £600 for repair on a vehicle that's almost 10 years old :-( it's been very reliable up until now, which is why I am tempted to get it fixed. As you never know what you will buy with about £1,500. Something that could also go wrong within a few weeks. Good video by the way, I too had to have circuit board cleaned up about 2 years ago due to corrosion.

[@cadreyh3559]

we have a megane 04 that wont pass emissions due to a fault in the electrical system, that will cost 20 000kr to repair, im gonna give this a try to see if your video can get us back on the road. None the less thx for giving me hope, if all else fails ;)

[@elmarievorster3218]

Thanx Paul. I am in South Africa and it is warm weather. I washed my car and after that the trouble started, so I can believe it is water that caused the damage.

[@mrtexpert1404]

It does sound like a water problem then, try removing the circuit box, disconnect your battery and maybe leave your bonnet open and the circuit board somewhere warm for a few hours, put it all back together and see how it goes. Failing that like o said previously diagnostics will be the only way to go

Paul Higgins Hi Paul I have a problem with my 04 megane it is a 1.9 dci .... when you put the key card in it comes up "steering locked" (the steering lock is physically on) and the car doesn't start ..... should I do the fuse box bit or is it something else ?? .... any ideas much appreciated

I love my Renault Scenic Privilege, comfort is great, it has everything I could ever want in features, everything is just in the right place for me, a lovely dashboard display but repairs, repairs, repairs. Renault have skimped on the quality of its parts, except my garage says the exhaust which rarely needs work done on it.

Cool vid bro One for the algorithm

[@aladinfox4098]

Great video thanks. My clio is doing this kind of thing an hour after i had parked it up like it was possessed . I am hoping its a similar problem though i think the fuse box is to the left under the steering wheel , anyway i am just waiting for it to stop raining☔

Thanks for the information.. Just bought a 2006 renault megane II 3 door 1.5dci diesel.. Lets see what happens to it.

[@siddill5395]

[@DriftersGaming]

0:08 if you own a megane its a familiar sight electrical fault on the dash or not,there is always something wrong with them.Had a red 03 plate for 2 weeks and had everything from suspension knocking to a bad starter.Had to fight our money back,bought an 04 scenic 1.5 dCi after,thankfully that is a bit more reliable,other than the damn window regulators

[@DriftersGaming]

3 years on I’ve had another megane(cheap insurance, my hands were tied, 17 at the time) and it gave no trouble, I miss the thing daily, I completely forgot about this comment and just found it now looking at getting another megane on the cheap because of this issue😂 250 quid for a diesel estate with a fresh test, sounds good to me!

[@Wirgleys236]

This saved our bacon today after a fuse blew during a jump start!

[@wac36]

Great video, what are all the fuses? I'm looking for the window fuse (3 door megane). Passenger window won't go down after I connected a regulator wrong on the drivers window. Interior fuses are not blown, thought it might be in the engine bay fuse box?

[@radu6997]

Hello Paul! nice job you did with that car! I have a similar problem with my Megane II, 1,6 16V 2005. Once my engine stopped while decelerating(~20km/h) and after that the car didn't start. 2 days ago it happened again, but this time the car was parked and i couldn't start it. Both times i took the car to a service and left it there over night, the only problem was that in the morning the car was running OK. They said that it might have some issues with the alarm and immobilization system, so i had the alarm disabled. Drove for about 30-40km and start/stopped the engine for 20-30 times since yesterday and no problem yet. Could that be a fix? Thanks in advance, Cheers

[@garog2541]

Awesome video Paul!! Maybe you can help me. Have a Renault Megane II CC. Could not start it (immobilizer kicks in). Towed it to the shop and they changed the plate that is connected to the - (negative) terminal of the battery due to corrosion. No it starts and everything works but the Service warning light flashes a couple of seconds and then gets continuously lit with the message: Steering check. The shop could not reset the error message and want me to book a new appointment. Read that it might be the "Steering wheel angle sensor" that needs to be reprogrammed. What do you think it might be? Appreciate if you could help me out, Thanks in advance!

[@rmt5820]

Hello Sir! Tnx because of ur useful video. U know I wanted to change my console lamp to led but now doesn't work even the original lamp both of them u know what's the problem?

[@MightyAj]

Great video! Just a bit of advice... I have megane and the heater fan won't work in all 4 speeds anymore which I took to garage but seem to think it would be expensive job so I didn't bother. Also for some reason my drivers side back indicator keeps on blowing and replaced 3 bulbs in the last 2-3 months. Could any of the fuses you cleaned up here be related to the fan and back indicator? Could this be a potential fix to those issues? Many thanks

[@albertsjoberg4503]

The fan is likely to have corroded pins on connector to termo resistor in blower. it's hard to find the termo resistor and somewhat even tougher to get it out for cleaning, so let it all sit if possible, just unplug the connector and clean both male and female contacts.

[@muhammadsherby4891]

Hello guys, for all they have the airbag warning light problem, I had this problem before, I went to Renault service center, they told me the problem is the spiral cable is broken ( it is the part connects the steering wheel airbag with the system, which the arms of the window wipers and head lights are connected to) and the diagnosis was correct. I changed this part ( it costs about 300 US Dollars) and now there is no warning light. If your steering wheel is making a clicking noise when you steer left or right ( like the computer mouse clicks) so, you have the same problem of the broken spiral cable.. I hope I was clear and helpful.

[@francoisvlok3326]

Hi Paul. I was driving along and next moment felt a shudder and Renault Scenic showed "Electrical fault" and stopped right there. Then all the error messages appeared , handbrake could not unlock, not even registering that the keycard has been removed. Disconnected the battery to "reset". No change. What could this be? Could it be a broken cambelt and the electronics trying to protec the car?

[@propertyofAllah1]

Thanks for sharing, I have a Micra 1.5 DCI is has the Renault engine, starts and drives fine, but when driving and I put my foot down engine light comes on red engine light and seems to loose very very slight power, just about to notice the very slight power loss, does not go into limp mode, plugged in a code reader and came back with p0685 ecm/pcm power relay control circuit open and p0670 glow plug control module control circuit open. I have replaced fuel filter and glow plugs, but still same, cleared codes but comes back on Thanks for any help advice guidance

[@merawatchvideo]

I had a similar problem on my Grand Scenic 2004 1.9 Diesel. As i was driving the powersteering stopped went stiff and dash displayed steering lock and electrical fault went back home and parked it up and tryed to start it again would not start. Thought it was the battery and put new battery in and jump started as well but still no good. Did make clicking from glove box and when in ignition position opened the bonet and moved the leads to ECU behind battery it made a noise. Had to take it to a Renault Specialist, used ECU and used card key fitted cost £340. Car is working fine now. Still getting the "check ignition" light from before this fault. But car was working fine no problems on pick up, till recently some times the car is not picking up that good. Will try changing the glow plug control module.

hi, great vid. my husband followed your advice after suddenly experiencing problems. now though the lights come on on dash but the car wont start and windows/locks will not work. the battery is fine any ideas? TIA

[@mrtexpert1404]

Hi sorry to hear that, my only advice would be to try it again, have a good look underneath the chips on the circuit board to see of there is any corrosion and if there is clean it out with wd40 and a piece of paper. also check the fuse for the windows, double check all the earth connectors are securely fastened from when it was taken apart to try the first time, if it still fails to start it may be worth letting a garage have a look at it, this works 9 times out of 10 but renault electrics are notoriously bad and there could be another problem that this won't fix

[@garypeternolan]

Water got into the looms in the passenger side of my renault megane convertible cabriolet. I dried all these off and there was some corrosion and a few of the wires seem to be disconnected! Is there any wiring diagram I can look at so I have an idea where the wires connect in the loom again?

Hi My Megane Estate 105dci 2008 went crazy yesterday, firstly the Check airbag light came up, then followed by the steering fault, then braking fault, at the same time all the doors started clicking, opening and closing and the lights started going on and off along with the hazard lights, I turned around and went to my garage, who suggested buying a new battery, but as they said this might not be the answer, (as it's possibly an electric fault/ I then tried the car again and all was fine, so drove it away, it was fine today. I started searching for an answer to the problem and came across your video, as it was aslo raining the night before, I'm wondering if this is the same problem and if doing this will solve it?

After a long trip inland it will start every day for a week or so - I live near the sea, do you think it could be the salty air? That is, could it be the same electronic fault? i think the fuse box is in a different place though... Many thanks for your video and help!!

[@mrtexpert1404]

Hi, I don't this model of car suffers the same electronic problems, however I would suggest getting some auto diagnostics done at a garage, persistent non starts could be a symptom of a wide variety of things, sensors, inadequate fuel pressure, blockages, low compression...
