How to do wire repairs:
• How do I repair damage...
Hi
This 2004 Citroen C4 1.4 petrol, engine code KFU, came to me as a non runner, with the fault codes P0201 P0202 P0203 P0204 P0443, all indicating an open circuit.
Sometimes the car would start, would run for a few seconds until stop and not restarting.
After some investigation, I found the issue, but the owner wanted this to be done as cheap as possible, so watch the video to see what I came up with!....
(Important: I do not recommend to do what I have done in the video, replacing the whole unit would be the correct procedure to repair the fault. If you ever do something similar, do it at your own risk...)
Hope there is some valuable information for someone out there, and that you enjoy the video.
Any comments or questions, please put them below.
Like always, thank you for watching!
Hi, Great stuff you put out. It would be even better if you could make more detailed video's ie. how you traced wire from coil 1 to finishing adding the temporary relay. Also where do you get the schemstics diagrams from pls.
It is complicated... I know you can not please everyone...
Some people criticize me for too many details/talking, others want more.... lol
Anyway, thank for watching and for your comment!
Schematics are from Sedre....
Hi I have a citroen berlingo 2009. No water from washer pump. wipers work but no water. I have replaced the pump and the fuse is fine but i did replace it anyway. Any suggestions have you experienced anything like this before. would really help been like this for four months and an auto electrican could not figure it out. Much appreciated
Difficult to say without looking at diagrams...
Try to scan it, and and look at live data, see if the stalk is working as it should, etc...
@@LMAutoRepairs Okay thanks do you do diagnoatic work for public?
I do this as a part time...
When money is short and the customer just wants their car to run this repair is just fine and professional. Your solution is definitely not a 'back yard hack'. Your an ace diagnostician Luis. You could get a job in a high end workshop anywhere I reckon.

Hi Buddy The key was your wiring Diagram, and yes it did look like a factory fitted Mod for Citroen, the customer should be really happy with the big saving, just shows what can be done, IF; you know what your doing, another good Video
Thank you for watching!
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! I've had relays fail on a few cars Ford, VW and BMW (sticking DDE relays) at least they were pluggable so could get them running again. Nice to see you've renamed your channel! Big thumbs up!
thejoneseys
Absolutely agree... it is a simple mechanical relay, what do they expect, that would last forever?
I still think is all about make profit selling this modules when a simple relay fails...
Yes, the channel name has changed... logo will be next...

i tried to open my 2009 berlingo one today, it broke into pieces, everything in thick glue inside. Such a bad move from Citroen, apart from anything can't be recycled at end of life.

Does any one knows where to find a relay like this to buy please, and could you send a link?
Thank you!
Buenas soy de Uruguay. El pin 86 relay de donde toma señal ? Tengo el mismo problema. Conecte todo pero queda la bomba de combustible siempre prendida cuando le doy contacto antes de arrancar. gracias y muy buen tutorial
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.
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!
Absolutely superb job Louis.

I have problem on c4 2012 how to get to you to diagnose. It was parked for long time and lost key, managed to do key not from dealer but it won't start. I have been told to change bsm but remains the same, when I short two fuses on top of battery connection it get electric on dash and start but it gives random faults change the connection on top of battery second hand, still the same. Need to jump fuses. Changed preheated relay still no improvement
Had code P1694, but also forgot to mention that after ot started after lots of attempts the prelast time, i had a "low oil level" warning and added it almost 1,5L of oil...now guessing if it's possible that the oil level sensor prevent engine from starting to not damage it?!...
Sometimes you can only do what the customer is willing to pay. Big Thumbs Up..

Hello, I have a problem with my Citroen Evasion 2002 auto. When I try to start it, it cranks but the engine does not start. I found out that there's a problem with the ECU (TEXTON).

Hi, I have the exact same car in my workshop with the same faults. (Australia). The relay powers the injectors and the purge valve (reason for codes), and also the ignition coil (transformer coil at bottom of diagram), but also the fuel pump! Lots of loads on the one relay and only 2 fuses! Very poor design. Very easy to fix compared to security issues in later models.
👍👍👍
Very good explanation and testing procedure could the faulty relay have been caused by the faulty connection you cleaned causing the contacts to over heat just a thought thanks

Hi
Indeed... it could have caused spikes that would have lead the relay to fail... it not... lol

Hi, I GOT problem with pneumatic suspension ecu of citroen c4 grand picasso 2008. I have diagnosed myself there are three code's came which are 2 of them related from pneumatic suspension i guess, basically both codes states " U1324 fault: absence of communication with the pneumatic suspension ecu. No single".
I got 4 of these codes P1351, C155D, U1324, U1219.
I hope you give me help out

Hi sir,can you please explain to me me the connection to that external relay you made. Can only see the positive wire from the positive going to the positive terminal and to the number 10 fuse.
Can you please breakdown the connection from the relay to the Bsm
It is all explained on the diagram etc...
Watch the video carefully...
I don't recall all the ins and outs, did this years ago...
I would have to go and check diagrams etc... but you can do that yourself...
The external relay essentially bypasses the internal one...
First make sure that is your issue, by testing etc... otherwise you might gona be wasting your time...

hi my teacher , nice job, also love the new name for the channel

Hi I got a c4 coupe 1,6 and the management engine came up and a it says a anti pollution system faulty toke to the garage trying to identify the codes it says no errors so they clear the codes and was all fine till the following day when the engine management came on again and it says anti pollution system faulty! Could you please help me or advise me on should I do ? The car is running perfectly just the the engine thermostat not showing any temperature some times
That's a bit contradictory...
Had no codes, but codes cleared and message went away...?🤔
If that message appeared, there will be codes logged on the ecu...
👍👍👍
I wish you lived in my country. My sister has a C3 1.4 petrol and it tries to start, sometimes starts but failing. And has a lot of codes.

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?
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!
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
i have apparentlly the same problem with peougeot 307 which misfiring the cylinder 4
can i perform the same steps what do you think
Rahaf Aldoush
Each case can be different... if you have an issue on one cylinder only, it is unlikely to be the same issue...

The garage doesn't know the cause and suggested to try replacing parts to see if they go away and I'm not convinced.

Hey, I got the same problem in my car. I was wondering if you could send me a sketch diagram just for me to look if I´m picking the right wires. Or is it possible to just power the fuse without doing anything else? Could you do that please? Thank you.
Hi, 4 days ago I bought a 2004 C3, everything seemed fine. Drove it home, then the next day it stalled and wouldn't start again.
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
Indeed it could...
Check the basics first though... fuses, connections etc...
👍👍👍
@@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"?
@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...
Hi, Thanks to you tutorial I have been identify the fault of my C4 1.4. I have connected the line directly from the batery, and runs. But I can't see how do you have install the external relay. Can you show how to do it? Thank you very much! 👏👏👏

@@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 ..
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.
The connection is the same as the original...
I have just replaced the internal relay with an external...
😉
👍👍👍
@@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.
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...
👍👍👍
@@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.
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!
👍👍👍
I was wondering if the earth could not have been picked up off the bsi so you would then be replacing it like for like?
The relay you added would be shut down by relay 1 but the bsi may have other protocols in which relay 2 would need to be shut down first.
Long time since i have looked in a bsi by the way lol.
Well done on another great video.
Ian Baxter
Hi
The issue was that this BSIs are covered up in a kind of silicone... you have literally no access to the pcb...
I know what you are saying... this way works as good, the added relay turns on and off with the ignition, just like the internal one does...

That doesn't look like a limp mode...
Check connections, grounds etc...
Scan the car if you can...
Thank you for watching!
Very clever man. well done
Thanks!
For watching and for your comment!
Sorted ha ha ha. Another great video. The wiring diagram, is it part of the diag program or a standalone program. Thanks mark
Mark Eastwood
Thanks Mark!
Is standalone....
Hi sir. How can I get that diag box with the the electrical diagrams
Google...😉
Thank you for watching!
The best expert
😊
Thanks!
👍👍👍
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
Hi
Yes... scan the car... and see if there is any codes that help you finding the issue...
Thank you for watching!
Nice job mate,,,,,,,,,, "Sorted !!!!" I thought I was watching Bodge it and Leggit :-)

Fabulous work, I just was wondering where you get the ignition switch signal to activate the external relay. Many thanks in advance.
Omar Sameri
Hi
As per the diagrams... from the original signal...
Thank you for watching!
@@LMAutoRepairs what do you mean? what wire did you tap in to?
@@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.
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!
Possibly... is the issue is caused by the same root cause...
Thank you for watching and for your comment!
@@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?
@@powersled
No... sorry...
I am in the UK...
@@LMAutoRepairs Ok, We travel to London every year (not this year though) to celebrate the memory of Marc Bolan. Anyway, I got the car running! Thank You!
👍👍👍
Hello, I live in Brazil and I have the same problem with BSM, the scanner gives the same errors as your video, I would like the electrical scheme you did if you could help me to get my car back to work. Congrats on your video.
Leandro Souza
Hi
Have you watched the entire video?
Thank you for watching!
I've seen yes, I just need the electrical schematic to adptar and make my car work, I bought a BSM used with this open circuit problem. Thank you, please help me!
@@LEOTURBOTUNING- If you pause the video, the concerned part of the circuit is quite visible.
Se parar o video, a parte do circuito que te interessa é bem vísivel.
Adicional se abrires a BSI com algum cuidado. Consegues substituir o relé interno. É uma peça bem barata em casas de artigos electrónicos deverás encontrar facilmente. Desoldar o antigo e soldar o novo não é dificil.
Boa sorte.
Those relays in BSM are fixed in some glue or some electrically insulating paste and are imposible to remove them!
THE STIG
Hi
I know... is not very good...
Thank you for watching!
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
Tell me if when this problem occurs, when you put the ignition on, does the fuel pump start, because it doesn't give any sign for me?
I don't remember know...
Sorry...
Check diagrams and see what systems are powered by the relay...
👍👍👍
@@LMAutoRepairsThanks. Should i mechanically check the pump first or check the relay first? Because you are the expert, what do tou think?
Check that there is voltage going to the pump first...
👍👍👍
@@LMAutoRepairs Thanks friend. I found the problem. Thanks
👍👍👍
