My 2002 GV has been going into limp mode occasionally and wont rev past 2500. Usually this is come up as a throttle position sensor fault and its usually fine when I clear the code. I suspect this is down to someone doing a bodge job on it since the wires going to the throttle position sensor are clearly not standard.
The other day it went into limp mode again but this time it was turbocharger waste gate solenoid. I cleared that hoping it would come back while driving and I could pin point the cause. No luck with that. No engine light now but the car is hesitating at 3,000rpm and blowing blue smoke if you let it sit at those revs.
I noticed an oil leak that looks like its coming from where the intercooler meets the turbo on the drivers side. The engine seems to be whining more now as you go up through the revs.
Not really sure where to start investigating this. Could the turbo be on the way out and letting oil past the turbine and into the cylinders?
I actually had this same problem about a year ago and it seemed to go away after an italian tune up but no luck this time.
ANy advice much appreciated
