Too much to list on mine. I guarantee that any problems mentioned on this site has at some stage happened to mine (melting fusebox, maf's, coils, clutch pedal snapping, knocking suspension, electric windows etc etc).
Fortunately, I got a lot of it sorted out while it was under warranty. Some bits still need doing, though.
I was thinking of selling it not so long ago due to the reliability problems but I'm thinking that surely not much else can go wrong with it now (famous last words. I'll probably break down on the way home now).
