I bough my X3 here, brought my cars here for services too. Recently have my 5 series for service and check out the abnormal loud “whopping noise” on the back of the engine. When I picked up the vehicle, the loud engine noise is still there. The service advisor and the technician confirmed that and want to compare it with other 5 series.
It has been over a month since, the abnormal engine noise getting loud and louder each morning, I try many ways, text, email and voicemail, to follow up with the issue but no response. It is really unprofessional.
Not bring my cars here again
