I am new to the forum. I am glad I found this sight because there arent many good mechanics that can work on an Audi let alone trouble shoot a problem. I have a 1998 A4 2.8

I have two problems. First is the sun roof. It opens by itself while I am driving. No particular reason, just at random.

My second problem is more severe. It seems when the car is warm(after driving awhile) there is a hesitation or bucking at a low
RPM. Sometimes a single buck sometimes a few in a row. Right around 1.5 to 2 on the tac. As soon as you give it gas and get passed the RPMs it is fine.

I have taken it to several different mechanics had computers hooked to it while driving and it seems to random to trigger any codes.

Any help with either question would be greatly appreciated.

Thanks

Dean

 

Search the forum for the phantom, ghost, surnroof. This has been pster several times here or onaudiworld. If I remember correctly it is likely due to a dirty electrical contact in the switch.

for number 2, put it on a vag-com and see what codes are there.
