Intermediate gear?
Our 2012 JSW TDI has been flawless for the last 11k miles, bought used in 8/2019 at 132k. Yesterday the MIL came on, scanned w/ VCDS, had P2015 code. Googling somehow turned up this video in German, which clearly shows the inside of the V157 motor.

I thought it would be a good idea to open up the motor to blow the dust out of it and verify its' internal stop is undamaged. That went well, but I now realize the intermediate gear spins in front of a sensor. Does anybody know if the clocking of the intermediate gear matters, or if it's just an RPM sensor to verify to the ECU that the motor is spinning?
Edit: Went ahead and reassembled clean V157 motor with intermediate gear in random position. Fabbed a stopper for arm using a 1/4" shaft collar & stubby screw. Tested with VCDS, worked fine laying on the engine. Installed V157, test ran & restarted engine several times, voltage stays at .760V target when sitting on stop.
To answer my own question: It doesn't seem to matter where the intermediate gear is installed. It just needs to read the RPM of the gear.
When my craptastic spacer fails, I'll be ordering the fix kit from Dieselgeek.
