Some more news, took TB cover off, the potentiometer came a bit unclipped so it didn't move, cleaned the contacts, plugged it up and moved the potentiometer about, the voltages changed, so everything seems good there.
Went to reset the TB with the cover open, I can hear the motor turning but nothing was moving gear wise, now I also got a new error code:
VAG-COM Version: Release 311.2-N
Control Module Part Number: 06A 906 018 CG
Component and/or Version: 1.8L R4/5VT MOTR HS D02
Software Coding:
Work Shop Code:
3 Faults Found:
17967 - Throttle Valve Control part (J338): Fault in basic settings
P1559 - 35-00 - -
17973 - Throttle Actuator (J338): Lower Stop not Reached
P1565 - 35-00 - -
01165 - Throttle Body Control Module (J338)
17-10 - Control Difference - Intermittent
Guessing something is messed up as motor spins but not alignment. Anymore help (like dissembling further?) here or just try and get a new TB?
