Last night (rather this early morning) I was just about home after a 2 and a
half hour drive from Washington, DC to South Jersey, I started to get a check
engine light only when boost went over 1.0 to 1.1 bar displayed. The car ran
fine other than the light coming on. Any idea's? Would the wastegate freq.
valve through a light? The light would stay on from 1.0 to 1.1 bar all the
way up to 1.8-1.9 bar. As soon as I let off the throttle, the light would go
out. I'll trouble shoot during routine maintenance today. Driving back and
forth between New Jersey and DC put the miles on the car pretty quick. The
car is a 1987 5000 cs Quattro with MC/1 engine. IA chip and an AAN wastegate
for the adjustable spring. The car has 227,000 miles.
