NEED TO KNOW
> A washer pipe runs over the amp in the boot if the Bose sound system is
itted, so watch for leaks – the amp alone costs £1080 from Audi.
> The air suspension can su er from leaks
and compressor/relay failure. Make sure you can manually adjust the ride height in-car, and look for the car sitting at strange angles.
> Fuel tank senders fail, and fuel gauge will show empty. Budget £1k for new senders and pump. > The rear wiper motor often fails, or has a mind of its own. Not hugely expensive at £250, but worth checking.
> Suspension bushes now commonly wear out due to age, mileage and the tough terrain many of these cars will have done battle with.
