I am working on a 2001 audi a6 2.8l v6 wagon, with auto transmission.
I am having a no-start issue. DTC code 17090 (Vag) ... Issue - the car will not start and the ECM/TCM thinks the car is in 4th gear, even though the selector lever is in park and the car does not roll(it is in park).
Measuring block 11 under auto transmision using Vag-Com indicates the Ecm/Tcm thinks the the transmision is in 4th gear even though the selector lever is in 'P'......Any hints, helps, kudo's will be appreciated greatly...
Just installed a new to car but used engine, and the starter will not engage when the key is turned to start?
Does any one know how to test the wires leading to the transmision range sensor, or how to test the range sensor itself using Vag-com, Multimeter, or LED Test light?
