On a 2005 Beetle. Bought it for $400 with a transmission error.
17100 - Transmission Input Speed Sensor (G182)
P0716 - 000 - Implausible Signal - Intermittent
Took out the transmission, it was white glove clean and perfect inside, changed the sensor.
While I was in there also changed the DMF, pilot, CVs and most of the front suspension.
Rear main looked perfectly clean and dry so I left it.
Put the thing back together and the transmission error is unchanged, transmission still randomly downshifts and misses upshifts.
I assume at this point I need to change the mechatronic unit?
Is there anything else that could cause this?
