Hello! I've tried the procedure a couple ways, followed the video exactly, and so on, but I cannot get the rear pad thickness warning to go away. I've probably tried it a couple dozen times and that damn chime and little light still haunts me. Someone try to help me figure this out before I go to the only solution I know to shut off this damn light and set the car on fire. :banghead:

Please post an Auto-Scan for context.

Did you measure the thickness of the new pads? What was the measurement? What number did you put in the Adaptation channel?

I don't know, the brake job was done about 9 months ago by my brother when he owned the car, so I've been putting in 10 for the measurement, figuring there is probably at least that much left. The car will need rotors next time, so I'm not to worried about guessing wrong. He could never figure out the reset, and I recently got the car from him.

Can you also post a channel map for measuring and adaptations please. Also, let the car calibrate by parking in P, leave EPB off and shut the car down. The caliper motors should wind in and out a few times.... and they're noisy on the D3 A8.

OK, so you're guessing. ;)

Okay, I've let the car do it's parking brake adaption on its own and forcing it, and in either case, it makes no difference. Oddly, I can clear the codes and none are reported, at least at first, even if the pad warning light is on. I have a scan from a few months ago, when I had to swap out a strut and some fog lights and some other nonsense, it's a different story as to what's with the time gap. At the time of the scan, the brake issue was present and I killed the battery a couple times due to a pair of inadequate chargers.

Audi A8L Rear Pad Warning
Hello! I've tried the procedure a couple ways, followed the video exactly, and so on, but I cannot get the rear pad thickness warning to go away. I've probably tried it a couple dozen times and that damn chime and little light still haunts me. Someone try to help me figure this out before I go to the only solution I know to shut off this damn light and set the car on fire. :banghead:

Pad shims to give the spec you want to offset rotor wear?

Advance the stepper motor to where you want the count manually & by removing & compensating for the offset by reset then reinstalling stepper to do the ADP?

Install new rotors and pads and do a total reset?

Calculate the actual value and input in VCDS then do the ADP?

Get a viable battery charger?

My answers in red! I should note that a few times during the procedure, after closing the parking brake for the end of the job, the parking brake was set, so I was unable to follow the procedure since it already was set.

I did aim low when guessing the pad thickness, figuring putting in a falsely low number would trick the computer into thinking there was more to the rotor, which are due to be changed but not urgently

No idea what a stepper motor is!
Install new rotors and pads and do a total reset?
That really is my last resort, but I'm afraid that even if I did, it will still have the code. Maybe just the rotors?

Could try that, disassemble, measure, and reinput data. I did think that the procedure tricked the car into believing you had done the repair, though.

I've got one now!

Oddly, I can clear the codes and none are reported, at least at first, even if the pad warning light is on.
Light on, but no relevant codes... this may not be an EPB thing at all. That's what you'd get from a traditional brake pad wear sensor setup going open-circuit, as it would if the brake pads were worn down enough to cut the sensor wire, or if your new brake pad sensor connectors were not plugged in, or your new brake pads didn't have sensors at all. That last one is a pretty easy situation to get into.

I looked at your instrument cluster (address 17) label file, and I see a reference to traditional pad wear monitoring in MVB 121. However, I don't see a way to disable brake pad monitoring via coding in 17, which is usually possible. That's unfortunate. Anyway, I'd have a look under the car to see if there is a mysterious disconnected wire hanging from the car next to both of your rear wheels.

I don't think the rears use pad wear sensors; I believe the EPB module can figure out when the rears are too thin.

However, if the OP is indeed mistaking the pad wear light for the EBP light on the dash, then he needs to have a look at the wiring/circuit to the front pads.

Maybe he could post a picture of the warning light in question?

It looks like below, and it says "Service!" on start up with a single long chime.

Is it? What does the one for rears look like? I was going off of the fact my brother told me it was the rears that had needed doing.

I believe rear pads don't have sensors............didn't Uwe already say that too?

What about fluid level......?

All right, here's the video! Better than a picture. Ignore the dying key battery, that's new and I know I just need to get a new battery for it.

The rears have no sensors as far as I have found, the EPB can tell how much pad there is by how much it has to travel to set. Telling the computer the pad thickness is to give it a setpoint so it can account for rotor thickness. Also, I checked the owner's manual and found no differentiation between needing fronts and rears, it indicates that a shop needs to figure out which it is for.

Or you could go inspect the front pads for being run down and wiring or fluid level.......... :rolleyes:

I agree. I think this is either the front pads and their circuit, or the fluid level and that circuit. Both are simple "got continuity?" checks done directly by the cluster.

Circle with half moons


Yellow usually means pads and red brake fluid, switches.

Okay, I'll look into it in a bit and see what I can find. First, I need to do another scan, if I recall, it does keep coming up with the rear brake code after driving a bit.
