Excessive carbon build up on engine intake ports at 35k miles. Car purchased new, has oil changes by dealer every 5k miles, and is filled with 92 octane gas. Lots of people posted on internet over last 7-8 years that minis are prone to this issue and bmw hasn't resolved it. When asked if this should be routine maintenance, if this was driving or fuel issues, dealer said none of the above. Yet resolving this issue is about a $600-1000k repair! This either needs to be a routine maintenance, recall or service bulletin put out to owners/dealers. Bmw needs to own up to this issue.
