I just installed (about an hour ago) the 993 TBV in my 200q20v. Go for a
test drive and I am very pleased with the results (no more "bucking" with a
cold engine, no more "bucking" when decelerating, and a normal "whoosh" type
sound). However, one thing almost makes me wanna go back to my normal (and
broken) TBV, I get 1.3 bar boost where I would get 1.7 and 1.8 boost
The last three part numbers (bosche) on the 993 valve is "108" where the
Audi valve is "106". Is there an incorrect way to install the 993 valve? I
am pretty sure that I got 1.7 bar yesterday, and seemed to lose that when I
put on the 993 valve. Sorry for bringing up this issue again, but I don't
know where it could go wrong.
Thanks a lot,
1991 200q (105k)
