When I bought the car it came with a VW immobiliser/alarm, but only one remote fob. My local dealer said they manufacturer had gone bust and replacements were not available. After much research on my part I found the place in London that makes the fob. They offered to sell me the fob direct, but would not (understandably) tell me how to program it to work with the car (the cost was £25 including delivery). I then went back to my local dealer who first of all said the part wasn't avaialble, when I told them where to get it they then said it would cost £125 excluding labour! I subsequently bought it directly for £25 then took it to my dealer to be programmed. They then said it couldn't be done so I asked the supplier to FAX the procedure directly to the dealer, the procedure takes 20 minutes and for this I was charged £48 - I think I should have been charging them for the work I had done on their behalf!
Lots of broken trim - ashtray lids, speaker grills, seat belt clips.
Several routine parts required on a regular basis- I am on my third set of brake discs at the front and second at the back. Various suspension members front and back. To be fair some of these are probably just fair wear and tear for the mileage.
I average one blown bulb a month - more than any other car I have owned.
Complete new exhast sytem required after 120,000 miles - inlcuding the down pipe.
Electrical fault recently caused central locking to stop working, when this happens you can lock all doors manually, but not the back door! The footwell lights also started comming on and off on their own. I traced this fault myself to an open circuit in a wire which leads to the drivers door courtesey light. This wire was not chaffed or snapped, but had been subject either sabotage or negligence during manufacture or maintenance - the insulation had been neatly cut through as though by wire strippers, an adjacent wire had been cut similarly, but only half way around the insulation, located about an inch back from the connector between the door and the door frame bulkhead.
The air conditioning has been intermittant for some time now, even after being purged and re-filled.
The roof trim is comming away from the roof above the front window.
Water leaks into the passenger footwell regularly and also the driver's footwell, I have checked the pollen filter and this is OK so I suspect the door or window seals have gone.
