ok this is getting annoying. After an underboost fault code was recorded recently, taken after a cambelt service on my car , and after which there was a huge loss of power and erratic idle. Soon the power less went away, and the car was back to its normal self powerwise ( although still down on power as it turned out the diverter valve was not up to holding the increased boost of the remap). Now I have had the updated 'D' diverter valve fitted, and the power is huuuuge +40 bhp easily now its boosting properly. THEN THIS MORNING FOR F*** SAKE, started the car, took longer to start up then normal, accelerated hard a few times :-D. Then after idling for a long time and pulling away notived there was no turbo action at all, no power :-(. No warning lights however. Then restarted, turbo spooling up now, car rapid as ****. Then a couple more times the turbo just cut out when accelerating, restarting engine fixed the problem. Very similar to the problem on by BORA PD130 when the vanes stuck open. ( or closed was it?) Restarting fixes problem then came back couple times. This NEVER happened before. The minute i drove it away from garage 2 weeks ago, there was a similar lack of turbo, which only returned to 'normal' after 1 hour. Please help, what do you think? im reluctant to leave this garage as they look after me well in the past, but I think they are gonna be cluless when I have to go back AGAIN to fuc*in get this sorted.
