    Default Sydney workshop to diagnose secondary Air Injection System error

    Hey guys I have a secondary Air Injection System error on my 2006 Audi RS4, these are particularly hard to diagnose if you don't understand how the system works. Anyone recommend a workshop that REALLY knows their **** when it comes to Audi's of this Era 2003-2010. I don't want a typical workshop burning hrs and hrs AND replacing pumps and solenoid valves when they don't know what they are doing, typically it's just a old leaking air pipe buried somewhere.

    I'd have a chat to Arthur and Mark at Exoticars in North Parramatta and see what they can suggest.

    Try European autotech. I'm sure they have had a few rs4 engines out in their time...

    What’s the problem?

    Can you still hear the air pump run on cold start when car has been off for extended time I.e overnight?

    Not tried to diagnose myself. Starting with if the secondary Air pump has failed would be the best start though.

    Faults are:
