I've got a '97 Passat (same same really) and it's been a "kinda lemon" .. The drivers side door broke internaly right after I got it, and had to replace the mechanicals inside, then about a week after that the check engine light came on, and shows an oxygen sensor bad, which one? No one knows, and to find out it's gonna cost me $65 for an answer. Needless to say, it's still on, and will remain so until I have to pass emissions testing.
The car is also seeming to nibble a wee too much oil as well. I hear say it's an oil sipper anyhow, but still, my '67 Comet with a built 302 sips a fraction of the oil the Passat's VR6 does.
It's only got 60K miles on it so all these things I've had to catch and fix here and there are a little lemon'ish in my book, it's supposed to be a "nice" car, but so far it's been a money pit. ($12 for a cheap oil filter? YOU NUTS?).
Cheers,
Justin
