Latest development is that the dealer called saying that the part they are waiting on is the alternator and that there are none in the country, expected time is another 2-3 weeks.

Couldn't believe it, I asked if the dealership had searched or called other dealers to find the part. They assured me that they did and that none were available.

Still didn't believe it so I called a few dealers, all did show none in stock but finally got a dealer to do a locate for the part. He found one in Michigan and one in the BMW warehouse in Illinois, they were nice enough to give me the numbers of both locations so I called and verified they were available, called my dealer back and told them to pick up the phone and get my damn car fixed. Part is now being fedexed and is due at the dealer by Friday....

So aggravated with the dealer, my SA is nice and I'm sure he is just reporting what is told to him but the management behind the scenes needs a few lessons in customer service!
