Hi

Can anyone recommend a good company that can repair an ABS ECU.
Had a diagnostic done and it seems all the other ecus cant communicate with the ABS ECU and also the tool cant connect to it.
The fault is affecting the follwing
- power steering
- brake lights not working (most concerning issue for me)
- Speedo always on 0
- Auto gearbox, makes a big thump when the car is stopped for a while

Car is a renault clio 3
Was recommended by bosch to someone, but he quoted R3500 to diagnose it to see if repair is possible, that cost would fall away if I go ahead and he does the repair which could amount to R10 000 worst case

On ebay I get the following

That would exclude fitment and reprogramming.
Any suggestions

any modern car with ECU, weakest link,
especially when it fails.

difficult to diagnose, and impossible to fix accurately.
cheaper and quicker to just go to a junkyard and replace the module.

Does the ECU then need to be reprogrammed and where can that be done and cost involved

speaking from experience here,
if like me its the main ECU that runs the car, yes, you would need to get a lockset with its own keys and Body control module ect ect...

if its just the ABS module, and it doesn't need to be pared to the cars ECU, and the rest of it (depending on complexity)
you might be able to get away with a scrapyard module and be done with it,

problem is most modern cars, its rarely worth the effort, as many times it cost so much more especially if it then needs to be coded to accept the new modules.

again, in ANY car the ECU and computers are the WEAKEST link that will leave you stranded very easily.

you might have some luck, and its something simple, or you just dive into a world of pain and suffering.
and its easier to scrap the car due to the wiring and ECU being shot.
even though the engine still runs well.

me, id start with getting some good diagnostics done, at somebody who specilise in french cars.
likebody like renu-tech, or french car specialist, see whats involved, and if they can come out and fit everything.

you will need to scour a few scrapyards, with a photo of the part and hope and pray it does not need to be coded,
to the ECU, or something more in depth.

auto ECU might be able (sometimes) to repair these things, and sometimes the module is sealed with glue to prevent repairs.
if you try open it, it designed to snap the PCB to prevent repairs.

again, planned obsolescence and all that. modern cars and ECU's that nobody fixes accurately.

Sounds awesome, wont do!

I actually have a feeling that it could be the connector or the wiring loom (which is apparently a known problem for clios). Probably caused by the engine vibrations as a result of the worn out mountings
If only I could access the ECU which is sitting behind the air filter housing, which I cant remove since the engine bay is like a jigsaw puzzle and have no idea what is holding it in place and what to remove first without breaking any clips.

eish, hope you come right.
reminds me of back in the day when my BMW525i popped a headlight. Changing globe did nothing.
BMW wanted R5k for a circuit board.
A friend took it out and resoldered all the joints he could find.
Put it back in and off i went without ever having a problem again.

Yeah dry joints can be a naai.

Thinking about it , I actually popped one of the brake lights when the ECU failed. It was black inside.

The car still drives well except for the power steering feeling a bit different. The only reason I dont want to take the car on the road is because of no brake lights.
Is it possible to rewire the brake lights directly to the brake switch under the brake pedal.

damn straight, especially when its all SMD's and no schematic to work off
and its a 10 layer PCB, that's DESIGNED to break when you open it to fix it.

yikes that sux even more.
luckily for me the beemer was old, 1994 model so it was only 1 layer on that particular board with massive components, very easy to resolder

'n boer maak 'n plan.
I am sure there are many work-around-options.
We live in Africa after all :)
