S4 Engine mounts

    So i have recently been getting a progressively more rough idle and have just logged the car and came away with the following left engine mount solenoid valve (n144) error.
    Has anyone ever changed a mount on the S4 and if so how much of a pain is it? I have just had the timing chains replaced as they rattling for at least 30 seconds on start up so another big bill could be a little annoying.

    Just bumping this as I did not realise that the engine mounts are active.
    At idle the fluid inside acts as a damper and allowed to flow through a small hole. Above idle a solenoid valve activates to shut the hole and prevent the fluid escape. In effect "soft" at idle and "stiff" when revs are raised.
