Hello,

I am new to VCDS and I was hoping someone could help me identify the best course of action for the error that I am receiving in the car panel - Ellectronic Break Malfunction when the breaks are activated - as of now, I am only using <P> (park mode) to reduce the risk of the breaks not releasing. The dealership I took the car was claiming it was a EPB failure and needed to be replaced - not sure of this is the proper diagnosis here - Not to mention they are asking for an absurd amount of money hat I simply cannot consider fair - so here I am now learning VCDS and making sure I can understand more and more about Audi systems. I have scanned the car and the info is attached below - It seems that ABS/ESP is somehow having correlated faults (maybe fixing one will clear then all?). I would appreciate if you could give some instructions what seems to be a real issue (which part may be damaged) and what would be your recommendation to service the car - I do have one spare EPB module (not inserted in the car yet). I was wondering if this may be due some stick that may have damaged the wiring near the wheel? If that's the case, any clues to to detect this?


All help appreciated here. Thanks.

Check the connector in your left motor if there is any water or rust on pins, which may lead into this kind of problems. If the connector is OK, take a look on cables, maybe isolation on wires got damaged.

If a DTC shows as "intermittent "...the condition was temporary and didn't exist at time of scan. Your best bet is to clear all DTC. Scan again to see what returns. If nothing returns ..go for drive down town and back.

00473 - Control Module for Elect. Park/Hand Brake (J540)
013 - Check DTC Memory - Intermittent

So you check DTC Memory and you find

1 Fault Found:
02432 - Supply Voltage for Left Parking Brake Motor (V282)
012 - Electrical Fault in Circuit - Intermittent

Something interrupted the power supply. but is intermittent. Note existing at the time of scan. but
as of now, I am only using <P> (park mode) to reduce the risk of the breaks not releasing.
is maybe the reason its intermittent.

Scan again for any codes. use your brake. If any DTC return post to thread. If they show up as intermittent again you likely have bad/loose connector, wire, ground. Use WD to trace and inspect and test wires and connectors

STEALERSHIP will play the MIL lights as serious...but sometimes it's just a matter of taking 5 mins to clear DTC and scan.

Many thanks for the replies !

I did a quick inspection on the cables just to se if there was visible damage such as exposed wires or broken connector - nothing like that - cables are properly fixed and no signs of physical damage. I am going to check the cables again and run a second scan with a mechanic to see if they pick any inconsistencies. About clearing DTC, Should I simply clear ALL (including the ones for the ABS/ESP) that may be related to that? I do not need to have them there if clearing DTC could be the way to try now - just want to make sure I do not erase information that may be worth having still logged.

Regarding the Wiring Diagrams (WD), would you say I should check current and fuses? Fuses are definitely easy to check, but for the wiring itself, I will probably need a mechanic or some "how-to" advice that someone can refer to for such verification ( standard multimeter based testing?).

Thanks.

You now have a copy of your autoscan on this thread for reference. You can also copy your scan on VCDS after you scan. Then paste it in your word processor and save a copy on your PC.

You need to clear ALL DTC to see if and what codes return.

I don't think it's a fuse issue due to it just effecting one side.

Hello. I have the EPB J540 module replaced and now I am going to test the car. All DTCs cleared so that I can check if anything shows up again. Anyway, the fault was diagnosed by two people as being the module - at least that was related to firmware version that my model could be affected - for the good or bad, the module I have installed is the "H" module ( not the original "G"), which may be already the updated firmware one. Anyway, new module now for testing. Will let you know if I get anything relevant or if you are curious about this case.

BTW: If this fixed the problem, in my case I saved USD 1500.00 on this just not going to the DEALERSHIP. :) :)
