Lots of little electrical faults. Airbag lights, blowing bulbs etc...
Dual mass flywheel and clutch replaced with solid alternatives.
Front springs broken and replaced.
Front bushes replaced with neoprene bushes; they last longer than the rubber ones.
Both front window regulator cables replaced.
Wiring in both front doors has broken in the A pillar. Had to solder patch wires in to get the central locking working again. Have yet to do the driver's side, as the electric mirrors are no longer working, and I suspect that side.
Starter replaced, as it was turning the car over too slow to start the car when warm.
Have recently tried to claim on the Seat 12 year anti corrosion warranty, as the rear passenger door keeper is rotten at the C pillar. The keeper panel has rusted thin, and the stress of closing the door has now split the metal, and the keeper is flexing badly in the quarter panel. Won't be good if somebody leans against the door, for the keeper to rip out of the panel and the door fly open. Unfortunately Seat don't want to know about it, so the corrosion warranty is not worth the paper it's written on. I thought the days of cars rusting like this were over years ago.
Dash rattles and squeaks can irritate.
Despite the general wear and tear items, it has been a reasonably reliable car.
Not quick by any means, but the 1.9 TDI is reliable enough.
I am sure I've not listed all the faults, but most of them have been just general wear and tear.
Main concern is now the rusting of the rear door keeper; was not expecting that from a VAG brand car. Makes me wonder if there's any more rust I haven't noticed yet. I've seen cars over twice this age without any sign of this rust.
