Love my 2004 Jetta tdi, but frustrating at times! Looking for suggestions.
The car starts like a charm, but when cold, intermittently will have a hard shift- especially between 1-2 and 2-3. There is also a strong exhaust odor at startup. Once warm the problem is gone- exhaust odor gone- still not the smoothest shift from 2-3, but that's a Jetta.
In the last 6 months I have replaced all solenoids, tranny sensor CEL was on so changed that, coolant sensor changed, car was reset at a shop, tranny fluid was checked and is OK.
After reading through this forum, great info by the way, I'm going to take out the battery and clean the grounds underneath. I'm also wondering if it could be a engine temperature sensor? The temp gauge shows the car warms up, perhaps a bit slow, but after a short drive.
Any suggestions as the fumes are quite strong at startup, but can't figure out this issue.
