After the cold spell here in alberta my rear end went into off road position. How do I lower it back to normal? I read that some have bled the rear shocks but I don’t know how to do that. Can anyone chime in?

 

Check the 40amp fuse for the air suspension compressor. If it has blown, the suspension may be stuck in a high position mode.

I had this happen a couple of years ago after driving in lots of rain and then having it get cold very fast. The compressor had some moisture condensation in it and was not able to start --- blew the fuse and suspension raised to a "defaults failed" position.

May be a good reason for the initial "nitrogen fill" of the suspension system.

Good luck,

 

This. i've had a few faults in my air system, and each time it was the 40 amp fuse that blew. it's in the trunk next to the battery. For some reason it happens to me only when it's in cold temperatures.
