Yeah, I replaced my EPB module myself with a used one and coded it. Really simple job. Those dealer labor numbers are obscene.

See my thread here for some info and similar troubleshooting (Passenger front ABS sensor was the issue) https://www.audiworld.com/forums/a8-...2961445/page2/

Do a couple things before replacing anything. Check continuity between the wheel sensor wires and the ABS unit (easier to do before repairing the wiring). If you need a wiring diagram message me. If that is good, then swap the driver front wheel speed sensor and rear passenger. they are the same sensors. See if the issue follows the sensor. if wiring is good and issue does not follow sensor issue is in the module.


Then rebuild the ABS module. if you have an 04 I have an extra module what part number is yours? the 04 did not work in my 05, different parts.

Good luck.

I had to go another 6-8" down the loom from this photo. Appears I did not take anymore as I was PISSED.

Hey CU52, I have had this problem for a year now and it bugs the **** out of me. This is my trouble code.

I'm assuming its a faulty wire somewhere. I had the module rebuilt last year. I also changed the brake switch and the wheel speed sensors. I ordered the online manual but I don't seem to understand how to read it. In the service manual, I search for N136 and I come up w the picture attached from the manual. Im assuming this is at the module connector but I can't seem to decipher the page and how to tell which wire is which for the outlet valve. I also attached a picture of the connector from both sides it that helps.


What pins would the rear left outlet valve be?

I would think that the issue might be the actual pump of the ABS system. The ABS electronic portion you had repaired is the brain. That controls the pump / valves that are the block next to the module with all the brake fluid lines. Possible that the system is trying to open or close the valve and cannot. I would think there is a way to test that with VCDS but it is beyond my knowledge.

Thanks. I have had this issue for a year and cant figure it out. it's not only irritating but I had spun out on a rainy day about 2 months ago. I might have to take it to an indy to try and figure it out.
