:frownfew questions regarding my bm:frown
1) when i hit the gas pedal i leave a cloud of black smoke behind me, the harder i push it the bigger the cloud, when i mean cloud i really mean a cloud, car is always serviced on time at bmw, has full bm history, it is a M47N engine, the engine is a new unit about 20k ago as the old one was totalled from the swirl flap prob, its had a new engine, injectors, turbo clutch, engine mounts etc etc, £13000 worth of bills from bmw for work (got it under warranty except for 2k labour) i have had the turbo breather changed to no avail, it has been remapped also! does anyone else experience this? is it a problem as i am extremely worried about the engine going pop again, so i drive the thing like an old tart now!!
2) i have heard that the egr value gets all gunged up afetr a short amount of driving and causes extra fumes to go into the inlet manifold causing the smoky cloud? is the true? and is there a way of stopping this egr value? and are there any bad side affects?
sorry for my extra long questions
any help would be much appreciated
