Brake pad warning will not go out.
 

Hi everyone, apologies for the needy first post but I have the brake pad warning light on and all pads/ sensors etc are fine !
I have had a friend who has just had to replace the wiring loom in his A8 for exaxtly the same reason but Audi UK will not make this common knowledge so I am trying to find a way round by disabling the warning for brake pads.
I have OBD eleven and have just ordered VCDS in the faint hope I don't have to spend £1500.00 with Audi to rectify the problem.
Can anyone suggest a fix or know how to disable the light on my car ?
Many thanks !
( I have checked all sensors with a meter and they are fine, also greased all terminals etc)

Just in case it is the "well duh," are you checking both front and back brakes and sensors?--if you thought wear was on one end. A lot of posts historically seem to end up being the "other" axle from where the focus or brake work first was.

Yes I’ve had all 4 wheels off and checked the lot.. even tracing the wiring up inside the wheel arches !

Got it. Next "well duh" that comes up too. Is fluid level correct; anything wrong with sensor there? I don't recall D4 light set up for pads, but sometimes the fluid related problem seems to get mixed in w/ pads too.

After that, no other easy ones I recall--besides yes, I would scan w/ VCDS to see what is in the brake (ABS) module code wise.

Yep, tried the fluid and if you disconnect the cap it comes up with a 'stop vehicle and check fluid' warning so that's no good...
I think the quickest way is VCDS or find a wiring diagram to close the circuit as close to the control unit/ dash as possible.

It's the harness they fail... I've got an A* with 188k ..I experienced the same issues

Rear brake sensor harness rubs on wheel
 

I had a sensor issue, it was the rear sensor wire which rubs on the wheel and wears through. Mechanic rerouted and cable tied it up out of the way.

I have same problem.
 

Hi did you get it sorted as I have same problem 2013 A8

Same here. 2013 Audi A8. Dealer verified pads and rotors are like new. But then quoted me $3600 to replace all ABS harnesses and sensors! 16 hours of labor. I told them to piss off.

So I'm either going to buy the left rear ABS hardness myself and get another shop to replace it OR I may just figure out how to short the whole thing. I sure wish the light could be turned off with VCDS or OBDEleven, but it cannot for some reason.
