Hi all! Sorry, Im from Hungary and speak a bit english 
I have got an M550d (2014,60.000km) I've got problems at about 1000rpm( at 1300rpm every good). When little I give accelerating to the car,it recoils then. the car gets
underway being late. This is not with all occasions so. I think of the
inapposite function of the little turbo. Can you help me? They do not
can in Hungary.
