just had to drive 140 miles with the EPC and the light that looks like the engine both on, by the feel of the car and increased mpg i think it had turned the turbo off itself and the exhaust sounded boomier than norm, norm is quite boomy due to full miltek, any ideas? i'm sick of spending money, just had to spend 700 quid on it for service, 2 tyres and a cracked sump due to a raised man hole in petrol station!!!! :(

I'd start with the usual MAF test, or getting the fault codes read, whichever's easier.
