Hello everyone, I have noticed the green suspension (lowering) light come on for 10 secs after engine startup and come on briefly several times during driving. Is this normal? I've checked for codes and there are none regarding air suspension at all, and the car rides normal/raises up to all four modes. Also, I have not seen any yellow suspension lights at all.

Hello,

If you shutdown the vehicle in "Dynamic Mode" then when you start it, it will illuminate the green light to warn you that the vehicle is in a lowered state, are you driving around in dynamic when you see the green light again, if you are in "Comfort Mode" or "Normal Mode" when shutdown and while driving and see the green light after start up and driving for some time then you may have a leak or worn compressor, UNLESS you are driving at hi-way speeds, then it is normal to see the green light when the vehicle lowers it self at high speed.

Just took a drive in comfort mode and the green light did come on 3 times, each time for about 1-2 seconds. This was not at highway speeds

I have also noticed recently that in dynamic mode, it has been releasing air quite frequently, even at speeds of around 40 mph

Mine does this in dynamic mode on the highway sometimes, and upon startup when I switch to comfort mode from dynamic.

To answer the OP; No, this is not normal.

+1 no not normal. I almost never saw my up or down lights except when I changed ride height or had jacked the car up. When my strut was starting to leak, I saw them at every start. I changed it out before driving it much more. And once again, I don't see any arrow displays except like before.

Sounds like the usual leak suspects--strut or valve block. When you park it for the night, look at it really carefully to see how it is sitting. Next day look for any corner drop.

Yeah that's what I've been thinking. I've checked for codes and there currently are none. I've let the car sit overnight in Jack Mode for 12 hours and I didn't notice any side down. Today, sitting at the red light, the green suspension light came on again for 10 seconds. I didn't notice the car lower itself. Could this be related to the fact I have an old battery?

When the green light comes on can you hear the compressor working? It's hard to tell sometimes, but the telltale is you can hear the compressor relay clicking on and off in the drivers footwell.

Junius

I don't usually hear the compressor running when the green light comes on but tonight I'll check very carefully. If a strut is leaking, wouldn't there be a fault code stored in the computer?
