Hello I'm new to Ross-Tech. auto repair support forum. I was looking for some advise on how to use the output test function to verify the auxiliary brake booster vacuum pump operation. I was looking for feedback on how to approach this issue. I initially purchased a new vacuum pump with matching numbers and have installed it with no avail. Further T/S revealed no 12vdc switching the pump any thoughts on this issue?
Troubleshooting:Replaced vacuum pump and relay. Verified fuse circuit was ok,hoping I targeted the correct relay. My hope is that coding is all that is needed. My experience tells me not to erase my problem as I'll lose visibility.
Symptom:brake pedal drops the floor,initially had no code or light failures reported on the instrument cluster. (Since the scanning),I have produced the (ABS) and (ESP).
Suspect Code:P1649 - 35-10 - Missing Message from ABS Controller - Intermittent
Prior work done: I had a used ABS brake module installed and coded by the local Audi dealer. I was told while researching the brake failure that it was possible to lose coding after battery failure? Is this the case?
