Re: Ur quattro - pinking (sic)
My car is standard apart from the head being ported. It has the standard chip
so it runs at a reasonably standard 0.75 bar boost. Its done 120,000 miles and
has £15,000 of service history. Its an 85 WR engine - not much else I can say:

Phillip, I assume you are experience pinging at medium boost.
You didn't tell us much about your ride. has it been modified,
if so by whom, and to what level, how old, engine history etc.
It could be that you have a failed pressure sensor in the
computer. An open will eliminate boost retard and cause pinging.
