OSR used to go down if left standing for a week but would level its self in a few seconds when started. Other than that no problems until one morning from both sides were down. Won't lift at all now?? Can you help??

 

Sounds like either a big leak or compressor finally gave in. You can try jacking up the leaky corners then try to get it to hold. Once it's up and supporting itself you can listen for leaking air or use dish soap to find the bubbles. To determine which corner leaks get it up and level then put it in jack mode. Hold both up and down buttons until it starts flashing. The corner that sags is the leaky one. If you still have original bags you should just change them all and the compressor while you are at it. You may still be able to buy a rebuild kit on ebay for the compressor though. Dont bus Audi bags they are crap. I bought Arnot and never had a problem. I was a slow learner on that one and waisted a ton of money with audi bags which all failed just out of warrantee.
