SelfLevel SUSP.INACT warning appears...why?

[Patryk1098]

In Addition;

My air suspension system works --except when it gets REALLY cold. My X5 is parked outside and when the temps drop into the teens -or lower- I get a "SELFLEVEL SUSP. INACT." message up on the dash. It doesn't go away when the temps go up or when I restart the car.

I've had the car at the shop for other work, and when the techs clear the error to perform a diagnostic, it doesn't come back. The leveling system works fine again, and all is well.

Has anyone else experienced similar symptoms; the self-leveling suspension system throwing errors in cold temperatures. Would love to know if this is a failing sensor(s) or just a failure in engineering/design?

I don't know what the error codes are, but I'm planning on buying this ECU reading tool to help try to diagnose the problem before temperatures rise on average:

Thanks in advance.

The only thing I can think of with your symptoms is that either the cold is affecting your relay, or the condensation is not coming out of the system, and something is freezing up. I'd check the relay first though.

That sounds interesting. I'll check the relay, but where would condensation build up in the system? Within the compression tank? Is there a way to either prevent condensation from building up, or a way to evacuate it (does the system have a way of doing that itself)?

Thanks for the tip!
