Definitely get the dealer to do the MOT. Then if they pick anything up they do not have any excuse not to replace under warrenty.
The option of going to a cheaper place is sound advice IF the car is no longer covered, as any issues identified will have to be covered by you anyway.
That said there is an issue with VAG ABS pumps. There is another thread on this forum relating to an ESP fault, which is actually the same. The VAG abs pumps are a real
problem with internal control module failures. You cannot do anything to spot it early, they just pack up and put a fault code out which disables the abs (big safety issue) and lights the dash light. Just google VW abs pump and you'll see that all VAG models are affected (Seat, VW, Audi, Skoda). The big issue with this is the cost - £1500
to replace. The problems actually lie in the electronic control module, but the whole thing is sold as a composite component by VAG, hence the cost. The best protection against this is to extend the warranty if possible, or swap the car.
Everything else is pretty much solid and is only subject to wear and tear - I'm not aware of any other component failures or specific issues, beyond regular niggles, eg. dash rattle, wet windows on the inside etc.
Sorry for the bad news on the abs pump, but at least forwarned is fore armed.
