My loaner 35i that I had driven since it had 2 miles on it told me it would be due for service at 4,500 miles (after putting 2,000 miles on the vechicle). I do a lot of short trips and city driving. What's strange is I am driving my "for keeps" 35i no different than I did the loaner, yet this one is saying my next service won't be due for 13,000 miles and I have 2,000 miles on this one. I keep waiting for it to change but it hasn't.
