2018 SQ5 Air Suspension Warning Light
 

In very warm weather I have had the Warning Light come on for the Air Suspension system saying failure call Service Department. This is followed by other systems like Auto High Beams all saying failure.
This seems to happen in very warm weather. Upon turning off the car and restarting everything seems normal. Any thoughts on what to look for?

My 2018 Q5 with air suspension does same thing. About twice a year it will display yellow warning in dashboard with failure message and drive to nearest dealer at no more then 50 kmh. Wait a few minutes and restart and its gone. Not worth bringing it in for the mechanic to tell me there’s no problem. Every morning I get the “emergency location” alarm message saying that its not functioning, usually that just means it hasn’t got my cellphone signal yet. That fixes itself in minutes too. That joins the beeping as I back out of my garage. Its a cacophony of beeps and bops, annoying.

After at least two trips to Service Dept Audi replaced a sensor that they say they could diagnose even though the problem goes away. Recommend you get the sensors checked.
