I am currently looking at a '94 9000CSE. Turbo gauge does not work and when given full throttle the turbo feels like it is kicking in out(waste gate?). Car has 117,000,new tires and exhaust,no loud valve noise. Opinions or ideas welcome.

Sounds like wastegate sticking, which occured on my '93 CDE at about the same milage. May be sooted up - in which case a strip and clean (of Turbo side only) needs doing. A full strip down needs a Turbo specialist capable of rebalancing the unit - so go for a PX unit, assuming that you are sure it is the problem.

Try applying a solvent like Plus-gas to disolve deposits from the actuator rod entrance into the wastegate housing first, to clear problem. This is what some Main Dealers do.

Unlikely to be Wastegate actuator, as these are very reliable and are aircraft grade according to the spec I have seen on them.

Not a definitive answer but...

CAn anyne answer this? If the boost guage isnt working, could the problem be a vacuum pipe defunct, causing the boost taper also?
