Allroad Suspension - same problem
I have exactly the same problem with my Allroad 51 plate - left parked the front suspension drops and the tyres are left touching the wheel arches - once started up the suspension lifts after 5 minutes, but that's a real pain - and the air compressor under the rear of the car makes a racket whilst pumping up the front.
Ride height indicators show no green lights when first swith on - press up button and they begin to flash - orange dash light also flashes whilst front lifting.
Took the car into my local Audi dealer who diagnosed a leak in the front driver side suspension air-bag - and replaced this at a cost of £576 !! car OK for a week but now front suspension dropping again - both sides - and more frequently than before!!
Dealer suggested replacing the air compressor pump but this would be £1,200 !!
Have no faith in Audi Dealers as fault now worse than before and I'm £576 out of pocket!
Any advice or assistance would be much appreciated
