Everything runs OK but I'm nervous about it being the symptom of gearbox issues.
I've had the car for 12 years and it's only started happening in the last few months.
Any help appreciated.

So the engine revs higher while the vehicle is in motion going up hill but there is no speed increase? If so it sounds like s slippage of some kind. What kind of maintenance have you performed on the X5 in the 12 years that you have had it? By the way is your X a 6 cylinder or 8 cylinder model?
