What could be causing my BMW 3 Series diesel to smoke under acceleration?
I have a BMW 3 Series Touring diesel automatic bought from new in September 2006. I have had 50,000 miles of excellent trouble-free motoring and arrange regular servicing at the local BMW dealer. Recently I have noticed black smoke emissions from the exhaust when accelerating. Is this an indication of something serious that needs attention? Can you advise please?

Might be caused by a failed turbo bearing oil seal.
