Not had it looked at yet,was told by a friend of a friend it could be an exhaust filter or something that could be making it burn more oil,but it costs 60 quid to get to it, to check it,im away at the min for 6 weeks when i get back im taking it to main dealers to get checked,my car is mint and has only done 57k which is nothing for a beamer so i want to put it right if i can,when i know what it is i will let everyone know
