Turbo stopped working, then started again. Why?
On a run down to Kent my car started to misfire/jerk at 70 going past Hemel
I thought it was an alergic reaction to hemel, but whilst queing for the M25 noticed turbo not spinning. On pulling away the car worked but only as a 1.8 QS, not a 1.8 TQS.
I carried regardless and after getting to Kent stopped and turned the engine off. Upon restarting it definately wasn't working so checked the hoses, all seemed fine. Left the car for a few hours and upon restarting the turbo was working again, but kicking in higher up the rev range.
Drove 100 miles home and stuck it on the VAGCOM and got a 'negative boost pressure' warning. Cleared it and everything is back to normal.
Also can the car select to run without the turbo? Wastegate stuck open?
