E63 warning light of car with up arrow

[Bron]

Hi guys

I literally had my e63 a few days and all of a sudden a yellow warning light comes on saying malfunction
It is a picture of the car with an up arrow inside the car diagram

This will be booked in during the week but out of curiosity I wanted to know if anyone else has experienced this and what it could be and what it could cost

See one saying Air Suspension but that's a car with both an up and a down arrow

On my previous CLS I used to get that warning, it has detected a fault with the air suspension.

Yes as above, the rear of the car has air suspension so it might have detected a problem.
