Major, major problem with thick white smoke filling the car interior, also coming out of the exhaust and from under the car, also under the bonnet.

This problem has now developed into a major problem where the car will only start up if left for a few hours or longer and when it does there is so much white smoke it's unbelievable. It looks as if the car is about to go up in flames.

A week a go I had the engine codes read, P1570 and P1557. engine ECU blocked and Turbo pressure control repectively. I had been having a problem with dramatic power limitation at 60mph and also irractic accelaration on light throttle. Both of these where intermittant.

Went round the ring road last night and only just got home before it packed up completeley, wouldn't even crank.

The next morning it started, ran a bit rough for about a minute whilst emitting masses of white smoke. The engine will only start once in about 5 hours, presumably the ecu dictates this to help protect the engine.

Can some one please offer an explanation - is this car dying???

My guesses are N75 valve or EGR valve or both? - had codes erased a week ago but have connected a reader since but returns 'no codes stored'

Could it be the head gasket but no visual signs of a leak. There was a whistling type of noise ealier this week.

HELP!!
