Hi Folks, hope you guys are doing well

The weather in Alberta was extremely cold roughly minus 45 Celcius degree which probably affect on electrical components? This morning I recognized my car was a bit lower on the left side (looked like accessed height which I've never used) then I start the engine then it raising normal, since the parking lot was bit offset on left side so I thought it should be a reason. After that, a yellow triangle warning light "Air Suspension Faults" while driving around 50km/h, nothing else recommended from message like "normal height only", checked 4x4 info there was no sensor faults at 4 corners and the light just stayed constantly while driving on highway. Fortunately, arriving to the office, completely parked then I checked raising, lowering & normal height which were working like normal :eek:, turned off and the light was gone away. Now I parked my car at a normal surface ground parking lot, left suspension at off-road height, scale clearance height at 4 corners and I will check again after work. So sorry guys since I'm working at a rural area without a GAP tool or a specialist that's why I could not give more information, but I'm really appreciate your advices. Thank you in advance!

P/S: My car just left repair shop yesterday after replacing leaking radiator and water pump :hmpf:

There will be no good advice we can give unless you pull the error codes.

If you want to monitor what it does after it sits for a while, you'll need to pull the EAS fuses when you park it. Otherwise, the suspension can auto-adjust itself, even when it's not running.

Thank you for your advices. So is it still safe to drive until I have a chance to scan it?

If it's not telling you otherwise, it's probably okay to drive.

Chances are it's a compressor or a spring or a valve block. Hard to say without scanning it, and it would cost a lot more to fix all those things than it would to get a scan tool and fix the right thing.
