Hello I would like to send a complaint about some BMW workshops to Munich. But now I don’t know if I should send it by email, in writing or by fax. Do you know the respective address, department or fax number? The problems are that my blower from time to time whistles at low position and 3 workshops argued that it is an airflow noise and the EuroPlus does not pay (I pay it also out of my own pocket WHEN they would be convincing)… Workshop meant it’s okay and late in the evening a call came: “I heard it with them but when I showed the vehicle to the fitter the noise was so quiet that we excluded it as airflow noise” …Great second problem is that when the engine is inserted the engine becomes much louder and thus faster, louder nailed. This is when it occurred after the turbo was replaced. Running quiet measurement should have been ok, the nozzles should have also been rated n and you could not do anything told me several workshop. One said that he has gone too much (85000km should be too much?). I have the nose full and would like to report this simply in Munich and you should recommend me a workshop who know the problem well…. kalle
