    i.e. if I remove the radio and unplug all the leads, how long is it before the radion requires the code re-inputing to make it function?

    dude, i bought one from a scrapy for 20 quid. left it for at least a year and it still had the code.

    I think it is because they use flash memory these days...

    Thats wht causes the volume problem, too

    As soon as the battery goes flat, the radio requires the code on my car!

    On later CANBUS Audi's it'll never require the code unless it is fitted to a different vehicle.

    I took mine out of the car for 10 minutes and it didn't require the code.
