Bought m135i xdrive the car has had nothing but problems and it has been back to dealership 4 time now and have been on test drives with 3 different technitsoins now and has has played up on these but not of these seem to notice any thing they have all told me that they dont know much about the car so how can they diagnose any issue at all this us puzzling to me the last time the car went un ut was given a update and ut came back driving worse than before so don't buy an m135i xdrive as the gearbox in it is rubbish and does not work properly in this car
