How to do wire repairs:
• How do I repair damage...
Hi
This car came to me with all sorts of faults...
ABS, ESP, engine, gearbox, electric parking brake, and sometimes airbag...
On the first scan (Unfortunately not on the video...), most of the faults were for problems/lack of comunication from the ABS module...
I had this same symptoms on a similar car about 7 years ago, so in a leap of faith I went to the same place where the problem was on that other car, and lucky enough... bingo...
Follow me on this video to find out what was the cause for all the faults...
Hope you enjoy the video.
Any questions or comments put them below.
Like always, thank you for watching!

A few months ago I bought my 1.6 HDI 2008 with 95000 cheaply from seller because of all warning lights to do with brakes, and DPF. Speedo was also not working. Took a chance on it after watching this video. Before tackling possible wiring issue though I thought it best to put into my local mechanic to run a diagnostic in case it turned out to be just a faulty wheel sensor and easy fix. Unfortunately OBD port was non responsive and still is. He was unable to find why even though power from battery is going to it. Decided then to put into main dealer as they were only going to charge me £55. Made them aware of problems and non responsive OBD. After they finished with car, told me that it needed a complete rewiring at a total cost of £4266. Said that wiring was badly corroded throughout, even they their report gave a 100% no problem r for all other functions of the car which they said drove great. They did not bother with OBD as it was pointless following the visual examination of wiring. Needless to say I was not happy with outcome. Told them where to go and that I would sort car out myself and prove them wrong. Since I had nothing to lose I stripped out the battery and the useless tape supposed to protect the wiring. Following the instructions in the video in tracing the wires, particularly the blue one to see if any were exposed or snapped could find nothing obvious..Ater spending almost a whole day and getting nowhere and being miserable I started to put everything back together. Just as I did so the blue wire came apart without effort about 25cm from the fuse. I patched it up. Started car and couldn't believe it when speedo was fully working. Ran car for a few minutes and rechecked wiring. Switched back on and all warning lights disappeared with exception of DPF. Ony driven couple of miles in car since. When I restarted car today, No DPF warning anymore but now I get faulty handbrake and esr. Even though handbrake is fully functional. Any advice to sort this out now and OBD issue would bo appreciated. But for this great video., my car would have only been fit for scrap according to the main dealer. Sorry for making post a bit of a saga but no doubt a lot of other people have been having same issues. Just take the plunge and have go yourself and save yourself a lot of money.

[@LMAutoRepairs]

That's great man... well done! For the obd... As silly as might sound, check all the fuses... If you give me more details I can check where the power to the OBD comes from... You check grounds first though... However, you can still scan the car, some tools can be powered externally, and you will still be able to scan the modules.... Thank you for watching and for your comment!

[@stuart6798]

You legend! Have exactly the same problem on a C4 Grand, just tried wiggling the loom and in and around the fuse box and now the faults have cleared. I need to fix it now, but thanks to your video I know where to find it. Thank you

[@leonlouiswalker]

Thank you for sharing this video. I had the exact same problem on a C4 Grand Picasso 1.6 HDi engine. ESP warning light would come on, ABS warning light and it also said Parking Brake Faulty. I went to get an M.O.T and those warning lights failed it. I then went to an Auto Electrician and he diagnosed: ABS Sensor (£48) needed replacing/fitting (£40) and/or EGR Valve. The ABS supply & Fit including V.A.T £105 (£48 + £40 + V.A.T) If that didn't resolve it, then the next step would be to supply and fit an EGR Valve. The valves range from £110 - £200 and labor is anything from £80+ as it is located in an awkward place. However, if you are lucky and have your own Diagnostic tools you could follow this video and see how you go. If you have an M.O.T due, beware that they will fail you with those Warning Lights. Good luck! :-)

[@nigelelyons]

Another THANKS from me! Was very reticent to strip loom too much but as it looked in great condition for the first few inches at each end. But right in the middle along the bulkhead behind battery the thin blue wire was corroded and severed internally. A quick insertion of a link between the break and all the errors have gone. Unbelievable! To help others I had had the following faults. ABS Fault, Brake fault, EPS fault, Depollution fault, Handbrake fault, Gearbox fault, Power steering fault. EGS Gearbox would only change using paddles from 1st up to 3rd. To get further I had to accelerate and drop into Neutral and then back into Auto mode to get 5th or 6th. Gearbox changed down fine! Speedo was just 2 dashes. ODB II reader showed lots of CAN bus errors. Blue wire sorted everything apart from Depollution error. Hopefully a reset and few miles will clear it too. MANY MANY THANKS !!!!!

[@LMAutoRepairs]

That's great news! Well done as well... thanks for sharing your experience! And for watching the video... 👍👍👍

[@SteveSingerFowkes]

This the exact same fault I currently have!

[@SteveSingerFowkes]

What link did you use?

[@ShaunieDale]

I've repaired faults in this area too. As the loom runs behind the battery at this point I believe it is due to acidic vapours from the battery leaching through the PVC of the wire and attacking the copper. The battery has a nice cover that guides all the gasses rearwards and over the loom. In my case there was no communications with the ABS unit and the car was reporting EPB problems.

[@VFRRiderFT]

Hey, Thanks for your video and yes I had the same problem unfortunitly I'm not adept enough to carry out the repair myself however a local Auto Electrician has undertaken the task for me. As you have identified in this video and the live stream you did; once the loom was opened there were many wires affected and that needed repairing :-( I'm hoping to collect the car today... Thanks again.

[@LMAutoRepairs]

Sound good! Hope they get it all sorted! Thanks for the feedback!

[@VFRRiderFT]

@@LMAutoRepairs I've just had an update from the Auto Electician and he has identified about 30 of the 60 or so wires as needing repairs, I've never had such a problem before but I guess this isn't the only car this issue affects; he has also identified some arcing dammage to that internel fused distribution board and will be replacing that too. It does make you wonder about all of these car fires with Vauxhall's over the years????

great video and good work I know it is a short video but one of the steps you have had to do. is. See the communication uce of abs and the line can either be with an opcislocope or true polymeter since for this it is safe to remove and check the wiring or well if it was another shorter route in good time greetings from Spain

[@alankane8686]

Edited. 6th April 2021 Hi Everyone, After trying everything that was obvious from watching endless videos about wheel sensors, Blue wires, corroded connect etc it turned out to be my front Passenger side Wheel Bearing because the Magnetic strip was faulty. I was amazed that this was giving me all the issues ie. Christmas tree lights Abs, Ecs, Auto Gearbox and more. I hope this helps and it was a pretty inexpensive part to fix compared to the warning alternatives 😬 Alan.

I have similar problem on 2008 C4 Grand Picasso 1.6D: Parking break works, but wont disengage. Have to flick dash switch and pump break to manually release electronic handbrake, not ideal. 'Hand brake faulty' & 'ABS /EPS warnings' on display. Some mention checking main dealer for possible software updates but Citroen UK want £90 just to drive into dealership, pop bonnet and plug in diagnostic. Will have a look at wiring like you but possibly a faulty EGR valve affecting parking break system. That's a £200 part and £100 to fix.

Hey mister your videos are very good and helpful i have 1 question i have automatick 2.0 16 v petrol grand picasso car was on automatick brake and i start moving but brake not let go now i have have milion mistakes gear box fault brake fault abs eps fault i can drive car only if i manuely change shifts we clr all mistakes but 2 left says left abs sensor not working and parking brake not working so my question is if i change abs sensor what u think its problem be resolved i mean is there conection betven sensor and parking brake? Thx in advance

[@LMAutoRepairs]

Yes... they are interlinked... Now, as for changing the sensor, make sure there is no other issues, like wiring problems before changing the sensor... otherwise you might change it, and the problem does not goes away... Thank you for watching!

I like this video , great job ,In the same case in my strategy, If the fault code indicates a loss of communication with a single module I check for proper power and ground circuit at the affected module , if the circuit are confirmed good , then test the CAN circuits for opens between splice to the CAN network and the module , if the circuit do not have open , replace the module What do you think of my strategy ?

[@LMAutoRepairs]

Good approach... can't see anything wrong with it... I also do the same... in case, experience told me to approach it in a different way... Thank you for watching!

Em algumas literaturas informa que, na K-line não deve haver voltagem, e em outras já que deve haver 12 volts, e caindo para zero volts, e retornando a 12 quando há comunicação entre o módulo e scanner. Estou aqui na dúvida. Qual informação está correta. O veículo apresenta o código de defeito c1208, "Informação de velocidade do veículo em curto-circuito 12 volts ou desligada". Apanhando muito aqui.

Verifica com o osciloscopio...

[@supermarketsweeps]

great nemo's do the same but they lose map sensor signal and egr problems , we got customer to repair himself as hole loom was damaged he wouldn't buy a part loom £170 , i think its because they twist wire and bend them round corners , great vid

Hi fantastic vid bud well explained I have a citreon c4 grand Picasso 2008 1.6L diesel 2008 that has a esp light and abs light on its also not shifting passed 3rd gear some sort of emergency mode I presume ,I cleaned the abs sensors on both front wheels still the same issue. I called the RAC to have a look and they've said it's a communication issue with one of the computer modules what do you think could be the problem I'd really appreciate the help bud 😁

[@LMAutoRepairs]

Difficult to say... If there is no communications with one of the modules, start by checking fuses, power and grounds to that particular module... Communication lines etc... 👍👍👍

Olá Luis Mateus. Parabéns pelo vídeo e pelo trabalho! Mais um seguidor garantido pela qualidade do conteúdo. Gostava de pedir ajuda sobre um erro que penso pode estar relacionado com o conteúdo deste vídeo! Tenho um DS4 de 2014 e acontece que neste momento regista o erro P1716 "Malfunction in the gear lever. Malfunction of the power line or poor contact of the device with the network. " O que acontece ao carro é que por vezes fica como "Auto" a piscar no quadrante e deixa de engrenar a marcha atrás, por vezes regista erro na caixa de velocidades e por vezes recusa-se até a pegar. Por vezes regista erro no ASR/ESP bem como até já registou erro no sensor do pedal do travão. Já foi substituído o comando da manete de mudanças e contínua a persistir apenas o erro P1716. Qunado acontece de o Auto estar a piscar consigo arrancar normalmente e passado uns kms o "Auto" deixa de piscar e a situação normaliza. No entanto acontece por vezes que desligo o carro e quando volto a ligar até aparece o erro de caixa e o carro nem pega. Tudo é e parece muito aleatório!!!! Alguma ideia ou experiência com este erro em concreto? Poderá ser um mau contacto ou fio meio partido que esteja a fazer mau contacto? Gostaria de ter uma opinião e desde já agradeço a possível ajuda? Obrigado e força no canal e no trabalho!

[@LMAutoRepairs]

Olá! Não, acho que ainda não encontrei esse problema... Pode ser mau contacto algures, um fio a partir... ou algo parecido... Se tiveres um osciloscópio, vê a rede em diferentes pontos quando o problema acontece... vê também se consegues comunicar com todos os módulos quando isso acontece... 👍👍👍

[@chrisi1909]

Seems very common on these cars, just had one last week, same blue wire that runs to Pin 7 of ABS. Broke at the same place and also the other wires looked funny. I was thinking that it was coming from the battery gasing.

Hi, I have this problem with my car now. The handbrake is stuck on and abs/esp service lights flashing. I have a fault code of U1213. Do you know what that is? I am on my own with 2 kids and not much money. How would I fix it myself please?? Thankyou for the video.

[@LMAutoRepairs]

I showed it on the video what the problem was (in this case) and how to resolve it... There is not much more I can do... 🤷‍♂️ Thank you for watching!

[@cristiandalleave6305]

Hello. What about replacing the whole wires assembly? It would be a clean job and would allow to avoid surprises like other hidden damaged wires.. is it so expensive to replace the whole piece? Only connectors to clip isn't it? I just now have the same problem and I think that a full replacement with a clever protection to prevent the new wires being damaged by the battery gases would be a good solution.. Is it really so expensive?

[@LMAutoRepairs]

If you do it yourself is is probably cheaper, still, if you but the entire loom will not be cheap... unless you go used, and get it from a scrap yard or something... 👍👍👍

[@cristiandalleave6305]

Thank you. I am thinking about that because looking at the wires there, they look like they were 80 y.o. .. I have never seen wires with such a bad look neither in Hot Water High pressure washers of 40 years old. Thank you. You are a good man and make good videos .. really divulgative and educative. God bless you!!!

Was the fault draining the battery as well as my battery is draining but it has got all the same faults

Don't think is this case the battery was draining... but to be fair, you can get all sort of issues when you have this problem... so might be that as well... Thank you for watching and for your comment!

[@carbonlarge]

Found the fault ??? (maybe) Checked the wiring around battery, nothing bad really !! then the top of battery fuse plate, looking at the thin wires going to the separate fuse panel where you found broken wire... all looked good but corroded, so I thought I'd strip and clean all contacts,,,,,,, the 4 bloody little fuses just fell apart !!! so i have bridged them out for a test....and dash is back to normal , hand brake working .....so now to make a permanent repair..... Thanks for pointing me in the right direction ..

Hello, I have a Citroen C4 Picasso and the fault is that when I change the gear selector on Automatic, it shifts by itself to reverse.

🤔 Check on live data that when you put it in auto that the gear selector is indeed requesting auto... You can have a bad gear selector... Thank you for watching!

sorry one more thing how much of the wire did you cut out

Ej zdravo druze. Kod mene isto. Citroen C4 1.6 semi automatic, isto pokazuje kad startujem motor. Primetio sam da samo u ljetni period ne mogu da ubacim vise od trecu brzinu, ja imam onu verziju sa F1 komande na volan. To se samo desava kad je napolju vise od 30tak stupnjeva. Samo stanes, ugasis motor i opet startujes. I auto vozi. Znam da nije rjesenje, ali ipak pomaze. Inace mozemo i razmenjivati iskustva zajedno, imamo tako reci isti auto. Pozdrav.
