I keep waiting for it to change but it hasn't.  |
I remember my X3 seemed to follow the same pattern (i.e.: showing 13,000 remaining at 2,000 miles). I think it must also consider the absolute mileage. It probably projects the maximum possible mileage, assuming you're going to do all highway miles. One it determines you're going to continue with the "short-hops", the "miles remaining" will drop faster.
I also believe the algorithm is different for the 28i and 35i. The oil in the 35i is subjected to higher stresses because of being pushed through the [hot] turbocharger bearings, and the engine is also stressed more, plus there is typically more "blow-by" in a boosted engine leading to oil contamination.
