Hi
Have an A6 4f 2006 with ACC, and these do have extra brake pressure sensors due to the ACC. The problem is not a faulty one in the ABS unit, but that I have somehow gotten an offset between the two sensors. One is fine and strats out at 0 bar, but the other one is starting off at a negative pressure.
No lamps lit in dashboard, but ACC diables due to DTC in ABS. Car brakes with perfect symmetry, so there is no air or anything causing this.
Feels like the VagCom misses a function to just zero these two sensors to 0 bar when no pressure is applied in the circuits.
Or do the sensors get zeroed as part of a procedure I have not found yet?
Have to admit that I suspect that I may have caused this myself from VagCom. Could be that I accidentally snugged the brake pedal while testing one of the functions in the ABS section of VagCom (cramped car, moved position in the seat).
Did'nt notice the issue before afterwards so not entirely sure, can't find a direct way to zero them back, and don't want to fiddle around without asking for some help from you guru's.
Below is the scan + a graph of the two sensors in action, so yo can see: Fully functional, but incorrect offset on one.
