Engine Clatter
 Bought for my daughter to take to grad school.  In shop in Denver several times for engine clatter. Always told noise was normal and dealer never put on customer list for repair. I even called Denver dealer myself and complained. Told normal every time.  Over 3 1/2 years noise increased.  Now car won't start and noise now sounds like an old diesel truck engine!  I understand having trouble with a car but do NOT understand dealers protecting the BMW name by not completing what would be a very expensive repair while under warranty.  Do NOT buy BMW products.  Get over the looks and demand service.
