ABS Electrical Fault

[Mitch3496]

I have a similar issue I know this is old but newish thread compared to what I’ve seen I was told at the garage that I needed a new abs module and was told cheaper to source one
What happened all the lights lit up after a blow out I took it to the garage and diagnostic ran a faulty and module I sourced one same part number and garage put it in and taaa daaa it didn’t work after coming across this thread shed some light the abs module has to be coded to my cars vin number?(would this be correct??)also when the garage took the old one off put the new one on and found it didn’t work I told them to put the old one back on should they have bled the air out of the braking system??
I now have flashing lights and brake issues and £££££’s down could anyone help please cheers davy

Sounds like a **** garage. If it happened after a blow out then almost certainly some sort of related damage from that. Either the brake pipes, the electrical wiring going to the wheel speed sensor or possible the alignment on the sensor and the pick up etc. The chances of the ABS module going at the same time as you have a blow out would be insanely low.

I'd start by making sure there are no leaks and reinstalling the original module, and then getting the system bled so you have a good pedal. You will need to bleed the ABS pump electronicly as well. That may be what they haven't done and why you have a bad pedal.

Then drive it (slowly) scan it for codes and go from there. Lots of garages are completely clueless when it comes to diagnostics. Find a reputable garage and it should be easy enough.

I called the seller and he said it should work it just needs to be selected from the menu- however the 2 auto electricians I went to haven’t been able to figure out how to do it. Does anyone here have a clue?

I had this same issue first time around and whatever the numbers are on your original pump are is what it has to be to replace it.

Here's how I did it:
1. Plug into VCDS & scan the car to get the old coding number from the old module.
2. Unscrew the Module from the old pump & then fit the new module onto the back of the old pump (Don't change the entire pump itself - it's only the module that goes bad!)
3. Connect it all back together with the New module on the back of the old pump already in the car & then reconnect VCDS & paste the long coding number into VCDS for the ABS & press "Do it!"

if it says "coding complete" rescan the car and clear any codes then test the module using VCDS to get brake fluid running through it to just be sure it hasn't clogged anything in the pipes.

After that you should be done and the lights should go away back to how its originally meant to be.

It's not coded to the VIN it's got it's own coding number which is coded to your ECU so it knows which part is what just have to get the number from the old one and transfer it over. (Part numbers do matter with this tho and it has to be EXACTLY the same.)
