7 years is extraordinary for a modern BMW. The bell curve suggests 4-5 years, with the newer, electronic-intensive ones falling shorter.
Like I said, 7,5 years for the one in my X3 is phenomenal considering the temperature extremes and option-heavy vehicle (electric everything, heated everything). Then again, the X3 sees mostly highway driving, and I usually don't use the climate control unless needed.
