Help!! I bought my daughter a used 2005 VW Beetle GLS Convertible w/a 1.8L Turbo engine. When I took it to the mechanic he said there were a couple of Transmission Faults

#01045, Indicating Tripronic Switch (F189), Not a Plausible Signal
#01317, Indicating Control Module In Instrument Cluster (J285) No Signal/Communication, Intermittent.

Recently, her car stick shift has been getting stuck on occasion, not allowing her to shift from Reverse to Park. She has to turn the car on & off a few times to get it to move.

From what I've read online, it sounds like a bad TCU can be causing the problem which produced the fault codes but would this be the source for the sticky shifter as well? No lights appear on the OBD....any help would be greatly appreciated! :confused:

The shifter sticking is most likely caused by a faulty brake light switch. The is a safety built in that requies application of the brake to shift from park. The brake switch supplies the required signal.
Could also be the magnets on the shifter have come loose causing the shifter to hang and the shifter position to be implausible??
