I've owned many BMW's including a 2005 GS and now a 2010 GS. I have never experienced any FD failures. The 2005 had 50,000 miles on it when I sold it and the 2010 currently has 40,000 miles. Even if I did have an issue I'd probably fix it in my garage and press on. I do however think that any final drive should last 150,000 miles without a problem. My question is: will the new water cooled boxer be fitted with a more robust FD?
