Turbo Quattro Coupe Wastegate
am looking for help in two areas.
1.) When I turn off my engine after about 30 minutes of
freeway speeds, it will either 'fart' out the tail
pipe or let out a mighty backfire. Since I have
just had a new turbo installed, I am paranoid
about damaging it. My mechanic, who has gained
a lot of expertise on this car, thinks the cause
is a worn wastegate. Any comments? Does this sound
2.) Where are repair parts (kits?) available for this
repair? My local dealer will gladly sell me a
whole new wastegate for $1200.00 and I am of the
opinion that theree must be a better cheaper way
to do this. A secondary reluctance to part with
my current wastegate is that is has been modified
for adjustable boost. This modification has been in
place for 9 years so I don't think it caused the
problem. When ABT was in Southern California, they
sold 'European' spec. wastegates and their own
adjustable boost kits for way less than $1200.00.
Thanks for any information and it is good to be in
contact with this group again.
