[@DavidsSperiskas]

Hey, official dealer of Peugeot, Latvia, did this same thing to mine petrol 407, even looks like they found your solution for my situation 😂, which is the same. But they really fucked up because ignition relay, which btw controls depollution and coils, wasnt really fried, just sticking, so when I drove for like 30kms, original relay started to work simultaneously with the new one, and engine management system crashed immediately. Had to use evacuator. So this works only if that relay it really gone.

[@LMAutoRepairs]

No really... something else must have been done in your case... In this case, is just a relay fitted in parallel with the faulty one, so if the faulty one works, will make no difference, as is just two relays enabling the exactly same circuit.... Hope it makes sense. Thank you for watching and for your comment!

[@thejoneseys]

Another great fix, they are lucky you could bypass it! It's crazy those modules are sealed with compound so you can't replace the relays, damn you Citroen/PSA!

[@leisuremechanist3800]

Great video, I have the same problem with a Peugeot with a similar box. But I'm afraid that there is some kind of security risk in that connection. If the fuel line breaks, the control of that relay 2 is probably supposed to stop the fuel pump.

[@LMAutoRepairs]

The connection is the same as the original... I have just replaced the internal relay with an external... 😉 👍👍👍

[@leisuremechanist3800]

@@LMAutoRepairs I may be wrong, but as far as I understand, the control of the RL2 relay coil is done by a microcircuit with NPN logic and the positive side of the relay coil always gets voltage when RL1 pulls. With that fix, one of the conditions is bypassed. The negative side of relay RL2 is not accessible from the outside.

[@LMAutoRepairs]

I get your point... What is the security risk? Both relays are on at all times with the ignition/engine on... I can't see any condition where relay 2 would be powered off with the first relay on... Unless I missed something... 👍👍👍

[@leisuremechanist3800]

@@LMAutoRepairs I don't know what that microcircuit contains and if there is any software associated with it, but I would assume that that microcircuit cuts off the current from the pump when the ignition is connected and sufficient fuel pressure is reached, for example when the engine is not started or when it does not start. I would also assume that that control monitors the fuel pressure and cuts off the pump if it can be concluded from the pressure that there is a leak in the pipes. If that NPN control had no meaning, that connection would have been implemented much more simply. So I would think that the purpose of that is to prevent fueling a possible fire.

[@LMAutoRepairs]

Yes, you might have a point... Would have to go a find out the strategy or functional description of the system to see if that is actually the case... Thank you for watching and for your comments! 👍👍👍

Its now showing the following codes: P0201, P0202, P0203, P0204 (Injector Control, all injectors) P0444 (Evaporative emission (EVAP) canister purge valve - short circuit) P0351, P0352 (Ignition coil 1-4 - short circuit) P0135 (Upstream oxygen sensor heating control) Think it could be something similar? Thanks

[@LMAutoRepairs]

Indeed it could... Check the basics first though... fuses, connections etc... 👍👍👍

[@zingrock]

​@@LMAutoRepairs So I've looked at the diagram for my car, its basically the same circuit as this C4, however instead of two separate fuses powered by the relay like the C4, all 4 components (injectors, ignition coil, purge cannister valve, x2 oxygen sensor heaters) are ran through one fuse. This single 30A fuse is fine. But the fuse doesn't show 12V with the ignition on. I tried your method of providing 12V directly from the battery, but sadly no luck starting the car. I haven't taken the fuseboard out yet. I wonder if the stored fault codes would prevent the car from starting, even if the issues have been "fixed"?

[@LMAutoRepairs]

@zingrock Usually no... The codes if stored will allow the car to start... Perhaps is not just that fuse that should have voltage, Perhaps the internal relay should power other things as well...

[@letangrutiri4208]

Im seated with that and i just cannot see how you connected your relay there

[@rockyfish3115]

My Peugeot partner 1,6 hdi 2009 is doing this it starts OK then it won't start then a few tries later it will. Any ideas? Please help

[@LMAutoRepairs]

Hi Yes... scan the car... and see if there is any codes that help you finding the issue... Thank you for watching!

[@cristobalvera7676]

what if i conect direct to the batery with 12 volts external switch?

[@MrRadu1983]

Those relays in BSM are fixed in some glue or some electrically insulating paste and are imposible to remove them!

[@LMAutoRepairs]

THE STIG Hi I know... is not very good... Thank you for watching!

[@crpth1]

The potting compound used in this boards is epoxy resin. It´s encasing the components of the circuit to protect from external agents, water being a good example. Additionally provide mechanical support against vibrations... With all this said. Yes it´s a pain in the a_s to repair. Which makes some sense Since they are not designed or engineered to be repaired. These parts are "supposed" to be discarded and replaced upon failure. Ask me not how I know, because I worked in a factory where we made a ton of these power train components. ;-) Regarding the repair itself, which BTW is mostly a DIY kind of thing. Depending on the particular relay location it can be "relatively" easy. The best I can say is that a Dremel type tool is a big help to dig out the potting compound. The rest is just a bit of solder. Really not much to it rather than patience. ;-) The relay itself cost some 0.2€ at the end of the production line. 4 to 8€ on the counter! The contact tips is usually minimal (keeping cost down). So they tend to don´t like too much current for extended periods of time. Which leads me to a tiny tip, keeping electric contacts immaculate clean is by far the best prevention over electrical failures in motor vehicles. Oops, wall of text. LOL :-) Cheers

what scanner you recomend for a 308 peugeot car

[@LMAutoRepairs]

If you only want it for peugeot, go OEM... Thank you for watching!

[@powersled]

interesting. On a 05 C5 all 4 injectors show "injector low curcuit" , would the same procedia do the trick? Greatful for quick reply, the car is on it´s way to the salvage yard!

[@LMAutoRepairs]

Possibly... is the issue is caused by the same root cause... Thank you for watching and for your comment!

[@powersled]

@@LMAutoRepairs Thank You for the quick reply, I work with old mustangs and these "computer cars" is not up my alley. Are you located in Holland?

I have the problem in this video and have done the test with the 12v led to fuse 10 . So I have to put in an external relay. In your video you don't tell us what wires to cut, can you help please.

[@LMAutoRepairs]

Hi I have roughly explained showing diagrams, etc... I don't recall now all the details, but they should be on the video... Thank you for watching!

[@torukonosamurai]

do you have any solution about " esp abs system faulty " before every start with bip sound and red signal on near speed screen and esp button doesnt work ..

[@LMAutoRepairs]

The solution is scan the car, check live data and figure out what the problem is... Something like that can be caused by many different things... I am not a wizard... Thank you for watching!

[@torukonosamurai]

@@LMAutoRepairs oh really .. so sorry why i am on wrong video which is think to be as witch , wizard and magic page ..it is my mistake I should be Harry Potter's Secrets Room next time ..

[@omarsameri8563]

Fabulous work, I just was wondering where you get the ignition switch signal to activate the external relay. Many thanks in advance.

[@LMAutoRepairs]

Omar Sameri Hi As per the diagrams... from the original signal... Thank you for watching!

[@kerolah]

@@LMAutoRepairs what do you mean? what wire did you tap in to?

[@user-qn6kb7gr1d]

@@kerolah Hahaha. Good luck with figuring that one out. I have the same problem with old used citroen. And mine is already modified like this. Or is it really right from citroen factory like that with the relay dangling there? Lol I'm confused and don't know anymore. But most symptoms are pointing to the relay. And it might be the relay 1, not relay 2 in my case. Need those cables for diagnostics to see what is going on. And to disassemble it all perhaps.

[@ta.tar.8125]

Hi, the broken ECU with the solid state relays. is from BOSCH, BSI, and BSM from siemens? witch means German that's why they failed?

[@LMAutoRepairs]

Ta. Tariku I didn't check the brand... but they are usually siemens, valeo or johnson controls... In this case, the relay that failed was a normal mechanical relay, not a SSR... Thank you for watching!

[@ta.tar.8125]

yeah thanks, i have seen johnson brand on a renault megane scenic -04 mk2 digital cluster when i was fixing it, that's normal i think all manufacturers use different brands, but johnson should be avoided like the plague since it's American brand/british, we know these two countries make poor quality products? italian Magneti marelli, and french valeo are much better. I.m.o
