Well I had the air suspension issue resolved. I went the Arnott air spring route.
Fairly straight forward install, if you are mechanically minded and have the tools no issue, DIY.
I decided to replace both sides, I only had one bad air bladder, small hole, the other removed air spring/shock is in good condition (70K kms on it).
Queensway Audi wanted to replace both sides at a cost of $2100 plus (taxes, top kit extra),
I was told that the cost was, "an expected cost to incur".
Ayway, I moved on when I was informed that $2000 plus repair bills should be accepted.
I would recommend the arnott product over the factory dealer alternative any day. I still believe the failure is unacceptable, especially at this point of time in the vehicles operation.
Arnott provides a lifetime warranty on the air spring, something Audi should have and honour.

 

Cool, let us know how they work out for you,....have seen a few other postings on other forums regarding these air bladders,...most people sound quite satisfied.
