thats quite high milage so I'd expect to need a set of shock absorbers if they haven't already been replaced
Other things to watch for are
Gearchange quality varies a lot. Pre-production gearboxes were noisy, but production RHD examples seem to be fine.
1.4 petrol engine is rorty, needs to be revved for performance and can feel sluggish on the motorway when the car is laden.
Emergency spare wheel is an optional extra.
Non opening bonnet foxes some people (front flap opens for checking fluids and revealing clips which allow bonnet to be lifted off).
Up to 2002 MY had terrible MW and LW radio reception. From model year 2002 radios are completely different and reception is OK.
Accident damage and parking dings to alloy body and structure will be expensive to repair, but Audi set up six special repair centres for A8s and A2s. If you have a prang it's essential to insist that an A2 is repaired at one of these centres, not any old bodyshop or one tied to the insurer
Seems to be a problem of turbo failures on the 1.4TDI if the car is not used much. Most reported cases are within first few months of the car's life.
The A2 anti roll bar has had a design change but no recall from Audi UK. There is nothing wrong with the bar itself but rather the 2 plastic collars that prevent the rubber mounts from moving sideways under load. These collars were attached in the factory before powder coating/painting. Corrosion occurs on the surface beneath the collar and eventually it splits requiring the entire bar to be changed and corresponding sub frame alignment. The new bar has metal collars. Audi may agree to pay for the work, costing £485
Colossal cost of A2 specific spare parts, in particular things like the panoramic glass sunroof that may have to be specially made if a batch has not been recently run off.
That is very helpful. I will write to you again if I need further help.
