The coolant pump failed on my 2011 335is with less than 27,000 miles on the odometer. In addition, the dealer told me my valve cover was cracked (which my indy mechanic confirmed). I realize my car is out of warrantee but shouldn't BMW bear some responsibility for these premature failures? Inoticed that BMW has changed manufacturers for its coolant pumps. The dealer replaced my OEM pump with the new version. Has anyone had experience with requesting a "good faith" repair?
