I have my AHU running in my audi 90. Took it for its first drive, ran great, but then started running a little rough on acceleration.
Not sure what was going on, I brought it into the shop and decided to try and check timing. I switch to 000, basic setting and it runs very rough, but I never get the "TDI timing" button.
I tried it on my ALH car, and got the screen and graph, no issue.
If the timing is WAY off will it not even get the option to go to timing?
Strangly the car ran great at first, but now starts a little hard and runs a little rough.
I am also wondering if a plugged fuel filter could do this. Maybe some left over crap from the gasoline tank got into the filter?
