I recently changed my rear brake pads because they were worn out, Everything went fine for a few days, but then the Brake Light goes on and ABS light flashes. Sometimes it turns on right when you start the car, but other times it turns on randomly. Ive looked at error codes with Vag-Com, and it says the problem is with the connection to the ABS module or something of that sort. Where is the ABSmodule located, and how would I go at getting to it?

What else may be the problem?

I bought my Audi from an auction, it was damaged, but not too bad, the whole rear was pretty messed up, including the lift gate, bumper, and a little bit of the frame. I got everything fixed and replaced, but may that be a factor of the problem? I love the car and all but this light is really getting to me, I garaged up my car just in case its bad to drive with the problem.

 

module should be under the rear seat. the rear hub has an abd sensor on it, vag com should have been able to pick up which sensor it is if it was the sensor. get a screen shot and post it

 

The car isn't going to bebad to drive, you just wont have ABS at the moment. My best guess, is that you either gotan ABSsensor dirty, damaged it,or didn't connect it all the way when you were changing the back pads.

If its the actual ABS Module under the hood, then you can either get a new one for a lot of money from Audi, or get it rebuilt for a lot less. Search and you will find a lot of info. on that.

 

what was the fault code?

 

ABS module is near the power steering reservoir.

 

if you dont fix the problem kind like i didnt on mine it will stay on, and your abs moduler will go bad and its alot of money to replace...

 

try reseating the abs sensor and make sure its allll the way pushed in.

 

Heres the ABS code
VAG-COM Version: Release 311.2-N

Control Module Part Number: 8E0 614 111 M
Component and/or Version: ABS/EDS 5.3 QUATTRO D31
Software Coding: 0273004134
Work Shop Code: BB 24302
1 Fault Found:
01203 - Electrical Connection between ABS and Instrument Cluster
03-10 - No Signal - Intermittent

I have taken off both rear wheels to check the sensor, and it seems that I shouldn't have done anything to it since it is in the front of the brake disk, unlike the pads which are on the back, so I don't think I did anything to them.


Also My engine light has gone on, and my VAG-COM has gone weird, saying that I need to login and whatnot, but gives me the codes anyway. Any help on these is very appreciated

Well I found a table of errors, and the last code on the engine has to do with the problem.
