Self leveling suspension inactive (missing)

[AechX5]

Bought an X5 E53 in a private sale about a week ago (UK). Not knowing the car very well I didn't think to check the warning on the dash (selflevel susp.Inact). Naively, I didn't even realize it was a warning until I started looking it up a few days ago.

Once I found out what it was and what it was supposed to do I went about trying to get the message cleared. That's when I found out that the whole self leveling suspension system has been stripped out, even the fuses had been removed. The car is level, the ride height is level and it drives really nice so not having the air suspension is absolutely fine by me as it's one less expensive thing to worry about if it were to go wrong, but it's left me with the warning on the dash that I can't get rid of.


Any idea's how to clear that message for good since the system doesn't exist anymore? If that's not possible will this cause the car to be an M.O.T failure?
