Anyone had any `staining` of these running boards?
Took the car in to the BMW agent and they washed it, came back with white staining, sort of bleeding out of the small rubber treads, complete with water marks on the gloss black window surrounds. None of these marks will come off !
The BMW agent says `they all do that !` Looked at their X5 demo cars and they`re 10 times worse than mine. I`ve never experienced this on the two other previous X5`s, or my `06 ML.
