Good afternoon
I have recently purchased a c6 allroad avant 2008 the rear suspension drops right down on both sides when left for a few hours
When i start the car both the yellow and green warning lights flash and after 1 minute or so they go off and the car is at the correct hight and seems fine
Today i put it in jacking mode and left it for 4 hours but when i came back the suspension was low again
This only happens at the rear
Everything else on the car seems fine
Any ideas
Thanks
