Hey guys. i have a bit of a problem. i was on the duel carridge way and suddly i lost half my power. idle dropped to 500rpm at rest and it sounds like its about to stall itself. also the exhaust note souds like a morris minor. like i said i have no power and it judders all the way along. any suggestions as to what it might be? BMW say it'll take 2 weeks to even look at it properly and 5weeks for a curtosy car!!!!
