Thanks to all. I'm new to the X5 range.

I was mislead by the reference to S220 and S226 in the vin decode then. I looked in the owners manual that came with the car and the only reference to self levelling and the error is on pages 99 onwards that is asterisked as possibly a fitted option and that ...

I'm not disappointed, just puzzled that I have the Sel Levelling susp intact message and a blown fuse in the suspension position in the fuse box. 32 amp last one on the right.

I have verified that the car is fitted with the 2 axle self levelling option (I think) from the vin

But reading the manual it shows a set of buttons on the dash for controlling unit (page 99 in my user manual)

This X does not have any extra switch for the self levelling system.

What gives?
