Look around the injectors. If there is soot or a black hard wax forming then there is a burnt injector seat and it's leaking past the injector straight out of the combustion chamber.

I also work in a garage mate and come up against this prob last year. I can tell you now its the flexi pipe just below the cat and they split but you cant see the soot or hear it blowing because it only does it when you put your foot down and the flexi opens up. If you strip out the air box and get a light and a mirror look down on the block side of the flexi pipe and you will see the soot there.

I spent to many hours looking for the fault and the only way i seen it was to strip the air box out and you will see it.

Hope this helps and i am 100% sure thats whats wrong with it

Maybe something with the crankcase breather set up?

Exhaust manifold, my mates E60 530D has been back to the dearler 3 times now with the same problem.

Outside chance of a leak from the spill off pipes from the injectors (the small tubes that connect to them) a slow leak on those may drip fuel onto something hot while the vehicle is motion.

Long shot I know, as I'm not even sure if the BMW has them.
