I have had trouble with the lambda sensor and had it replaced in May 2004.
Six weeks later another sensor went, it pushes the petrol through when engine is cold, that stuck on open and made the car judder and stall.
The engine management light comes on when it feels like it (Vauxhall can never find any problems)
My car is now in for repair as the cylinder head gasket has just blown (44,000 miles) (£500 quoted by Vauxhall).
The locks have stopped double locking.
Apart from the above nothing else major has gone wrong with the car.
The car is quick and nippy and generally OK to drive.
I have also got a Vauxhall Corsa 1.0 liter. It is a T plate and was made in 1999. I bought the car in January 2005, and for the first few month I had no Problems with it. Then in November I had to change the disc brakes and pads, when I had only have done 48,000. Then after this I had the engine management light come on because the idle valve went, this cost me £68 to get replace and that did not include fitting. The valve in these cars also go wrong. Then after I got this fixed the timing chain pad went costing me around £20. Part from these the car always starts up when I need it to, so over all the car ain't that bad, but I would not get the same model again though.
