dreaded air susp inactive
 

I got this on monday morning after a new england snow storm and have been reading post in here about it and had a few questions before i brought it to the stealer.
1st some details, 2005 x5 4.8is I was out sunday night and did have some wheel slip, (i saw a posting about that someplace in here)
I checked al the fuses in the rear and in the glove box, they all tested good, swapped the 30a out with another 30a just in case. I also noticed the light on the dash for the height switch is not on,

I also checked inside by the battery to check for any water and it's bone dry...

so my question is before i bring it in, is there anything else i can check or do to reset this fault? I read on another site that if you turn the car on and turn the wheel back and fouth 4 times that would reset, but not to sure about that one, and help here would be appeciated.
