Apologies, I posted that reply quite late and was safe-to-say quite tired by that point. Although the drive belt can operate the cam, some are also geared or chained within the engine, which I believe it is in most VAG engines so true, changing that is a good idea but changing a drive belt when it's still in good condition.. Matter of opinion, but I like to get my money's worth out of things. Although it's good practice to replace brake fluid, it's not completely necessary.
Only reason why I said that they're trying to eek more money out of you is because they'll probably charge you £300 just to change a drive belt. Services are worse enough at £470 for two oil services and an inspection? But I'm trying to say that you don't need to get this changed or that replaced, it's just that they always charge you an arm and a leg for something that might not really need to be replaced.
