Nope , warranty was worthless , finally almost broke even , money -wise , with help of a Magnuson-Moss Federal Lemon Law case . Court caught BMW & dealer lying , I kept their own service documents that proved I was correct ! I got the cost of a new engine & ECM , I then sold off the bike "as-is" on E-bay , since Grand Rapids BMW stealer could not be trusted at all . That bike should not have made it past the end of the assembly line in Germany , - so much for quality control !
Still was 2 1/2 years of stress on me though , I never got one pleasant ride on it , what with the predetonation knocking from the start & the later resultant piston slapping before 6 K Miles. ( Not to mention fuel pump failure @ 4 K & then rear-end noise after that ) When I picked it up new , I couldn't hear the knocking at the dealer with all the 4 lanes of traffic going on . Soon as I got home I could hear something not normal in my garage , they kept claiming it was valve noise but valves don't knock like that , ( I had 2 previous BMW twins ) . Idling was extremely erratic because of the constant predetonation . I found out from another guy on the BMWMOA forum had the same problem , it was the ECM not reading the 2 anti-knock sensors & not controlling the ignition advance of the engine correctly , ( defaults grossly advanced ) which trashes the engine . I had it in for service , the same problem 4 times , stealer basically would just blow me off , hopefully to them - past the 3 year warranty period after when at least $6000 , of parts only , would have been out of my pocket !
