    Hi there, I am new to this site and would appreciate any advice with the following problem:
    I have a 2005 A3 Sportback, 2.0 TFSI Quattro. The Emission Control light and the Engine Management light came on during the week and I am being told that I need to have a new Engine Control Unit fitted. The cost of this piece of kit in Dublin is around £450 (ex labor and VAT)
    The A/C has also not been blowing cold for a while and I am being told that the gas is full but a new compressor is needed at a cost of €720 (ex labor and VAT).
    Is it unusual for a the Engine Control Unit or the A/C Compressor to go in a car of this age?
    Does anyone know what the cost of these items would be in the UK, as I could go up to Belfast to get the work done.
    Any help would be greatly appreciated as I was shocked at the cost.
    Regards,
    Cunamara

    ECU failure is not a common problem, bosch ECU's are reliable enough to assume that failures are very very rare.

    I would do a vagcom scan and see what fault codes come up and then go from there.

    Thanks Robin,
    Got a diagnostic scan carried out on the car today. There was a notification that a software update was available, which, once completed, fixed the fault with the warning lights. There had been a recall on my car relating to this issue, so the diagnostic was carried out under warranty. Happy days!
    Thanks for the suggestion.

    thats a relief! Was it Audi that originally told you that you needed a new ECU?

    Yep, huge relief! It was not an Audi recognised service centre; although they did claim to have the necessary diagnostic kit. Needless to say, I will not be going there again.
