So, I bought a nice stock low mile 2007 E60 M5. A week later I had a reduced power code pop up so, I took it back to the dealer I bought it from and they sent it to BMW in Shreveport. It has been there every since. It started with a simple reprogram which turned into a new ECM and PCM, followed by a transmission issue. They have now spent four weeks trying to put a clutch in it and get it to work... So, of the six weeks I have owned the car I have only possesed it for one week. I call and ask what's going on with my car and the RUDE condescending ***** hat service advisor gives me a line of BS. So, I ask for a reasonable explanation as to why it has taken over four weeks and they tell me they've spent that time trying to diagnose it. Really? Over four weeks to diagnose a transmission issue? Anyone else ever have issues like this with a BMW service department or do I just have the worst luck?
