Problem after remap, possible engine dead

<< < (3/3)

GTIEagles:
Sounds the turbo veins stuck, causing an over boost which was probably heightened even more so by the remap and this caused the turbo to blow. New turbo and intercooler flush and you should hopefully be good to go.

Edit: just re-read your post again and as you had problems with the car loosing power before the remap and switching it off and on and would fix it, I would place my money on it being the turbo veins, it's the classic symptoms. My Audi a4 1.9tdi did the exact same thing and mr muscle oven cleaner and a long Italian tune up cured it. But once they start doing it, the turbo is usually past it's best so it should probably be reconditioned anyway. A good tip is if the car has spent all week doing sedate and short journeys, once a week give it a good thrash and this should minimise carbon deposits building up in the turbo and veins.

SiofChester:
Does sound like turbo, but there's a moer concerning part that the engine won't turn over. I'd be getting someone who knows what they are on about to look at it before doing anything else. if the turbo's blown all the oil down the exhaust and left the sump dry, you're looking at a whole world of pain
