Shifter problem Stuck on Park
First thing first. Though I have never posted before, I have been quietly reading your posts and learn a lot from you guys. I thank you for that.
Now, My problem. I had serious flooding in the garage that left my car (1998 A6 2.8) full of water. I had to replace the whole interior (front and real leather seats, plus the door panels). Expensive but at least I knew how to do it. The shifter on the other hand, is an issue I haven’t been able to resolve. I cannot move the shifter from “Park” position, nor can I start the engine on this position. The shifter-lock light (the one that warns you to press the brake pedal before shifting out of park) stayed on even when I stepped on the brake pedal. After some trials, I was able to move the car by pulling the shifter to neutral position, start the car and then put it into drive. But lately it will not move when shift to "drive" position. It feels like the trany does not engage when in "drive" position. But it still fires up in "neutral" position. The shift lock light started to flicker for sometime, and then it died out completely. I have recently changed the brake light switch following the advice here on the board, but to no avail. I am also experiencing difficult removing the key from the ignition, though this does not happen often. From a long search here, I think my next troubleshooting should be the TCU and the shift-lock solenoid. Am away from home, but would return in a week and continue troubleshooting. Any additional pointers/advices will be highly appreciated. |
Did you dry out the TCU after the flood? Checked it with VAG-COM. Time for some basic troubleshooting.

No I did not check the TCU. Honestly, didn't know the TCU existed and has such a major role. I thought most computing were done on the ECU.
So the TCU has been there since the water damage, over 6 months ago! Here is the VAg output, taken when the engine was off (key on "on" position) so 'am not too concern with the other engine fault at the moment: ----------------------------------- Address 03: ABS Brakes Part No: 8E0 614 111 M Component: ABS/EDS 5.3 QUATTRO D31 1 Fault Found: 01203 - Electrical Connection between ABS and Instrument Cluster 03-10 - No Signal - Intermittent Address 02: Auto Trans Part No: 4B0 927 156 G Component: AG5 01V 2.8l5V USA 8509 Coding: 00000 Shop #: WSC 00000 1 Fault Found: 00526 - Brake Light Switch-F 27-00 - Implausible Signal Address 01: Engine Part No: 4D0 907 551 AH Component: 2.8L V6/5V MOTR AT D01 Coding: 06252 Shop #: WSC 02324 12 Faults Found: 18010 - Power Supply Terminal 30: Voltage too Low P1602 - 35-10 - - - Intermittent 17967 - Throttle Body (J338): Fault in basic settings P1559 - 35-10 - - - Intermittent 17973 - Throttle Actuator (J338): Lower Stop not Reached P1565 - 35-10 - - - Intermittent 16684 - Random/Multiple Cylinder Misfire Detected P0300 - 35-10 - - - Intermittent 16690 - Cylinder 6: Misfire Detected P0306 - 35-10 - - - Intermittent 16689 - Cylinder 5: Misfire Detected P0305 - 35-10 - - - Intermittent 18014 - Rough Road/Engine Torque Signal from ABS: Electrical Malfunction P1606 - 35-10 - - - Intermittent 16890 - Idle Control System: RPM Lower than Expected P0506 - 35-10 - - - Intermittent 18034 - Powertrain Data Bus: Missing Message from TCU P1626 - 35-00 - - Readiness: 0110 1101 Address 17: Instruments Part No: 4B0 919 930 B Component: C5-KOMBIINSTR.

I'd check the TCU to make sure it looks OK (open it up and see if it's green inside), clear all the codes, and go from there. You might have a bad brake light switch.
Unrelated, but it looks like your ABS controller has failed. |
Thanks for the help.
I did change the brake light switch - followed the basic installation described here on several post. I left about 1/2 millimeter gap as recommended. Do you think I missed something? The ABS issue started as the infamous blinker (both ABS and Brake light blinking indicating something wrong with the ABS), but it got worse after changing of the seats. I suspect the ABS on the rear seat is not connected properly. I just want to get the car moving for now. |
Pulled the TCM out and boy, it was rusted as hell!
Hope eBay will have one soon, though the shipping cost will kill me :( Will post. |
