Hello all! good day! well i am going thru this issue, which is bothering me alot, i had ordered a set of brake pads for the front and the rear for my Audi A8 2005, just got them installed. everything was done correctly, using vcds/ross tech. now my instrument cluster shows this yellow circle with 3 thingys on each side of the circle, after doing some research i found out that the sensor cable might be loose, but i checked everything nothing seems to works, can someone please direct me to the right track, thank you all. have a great day

Did you code thickness of pads? Did handbrake test does good? Maybe forget to plug in in front pads?

darkchildbati

Thickness was registered, front brakes sensors are plugged in, I don't know where the problem is

Is a VCDS scan showing any codes?

darkchildbati

No codes what so ever

Mister Bally

Are you using the genuine Ross-tech VCDS or a generic tool? Generic tools will not list many VW/Audi specific codes that are not part of SAE standard fault identifiers.

I apologize if you're using the real VW/Audi tool.

darkchildbati

Yes it is an 100% original VCDS, got it done from my mechanic, he told me he hasn't seen anything like that before

My buddy did a brake job on a 08 A8L, using his $20,000.00 Snap On system to open and close the calipers, but came to my house for the finishing touch, it took me a hour +/- to get it right, it just would not take, but after inputting the info many times, all was good.

IIRC I added or subtracted a MM or 2.....

Hi johnny J thanks for your reply, me and my mechanic tried multiple time inputting the thickness of the pads, it would only take 12mm, and all the sensor wires are connected, i ordered quality brake pads, so i have no clue what is going on

Did your guy follow these steps, and did he do the "Function Test" ?
