Wonder if anybody could give me some advise...My 2003 X5 3.0D just starting smoking heavily and the the dip stick was bone dry. Very confusing because the oil was always on the mark, even after a long trip. The power though seems fine...going to try and refill oil and see...I also have an intermittent problem starting, then I have to move the gear lever from P to D and back a few times and then she starts again.....2003 out of Motor plan so I would need to first confirm the problem before having it repaired...It has only 140 000km (genuine mileage) I checked the history before I purchased the car on 125000km about 6 months ago..
