Subscribed. I get a pit in my gut every time I think of the sludge I see when pulling the dipstick or removing the 7l0 cap. My wife is the primary driver of the X5, and makes a lot of short, short trips, under 5 miles. The maintenance history that came with the car shows it's sucked oil into the intake at least twice in the past. And I sit on pins and needles...
