They're pretty reliable as long as they've been maintained! my girlfriends 1.8t is on 128k i think and is still going strong. I've only had to change lower arms, front tyres and give it a oil service every now and again. One thing i don't like about hers is that it seems to have gained a few rattles and creaks inside now - compared to my audi, it sounds like the interior will fall to bits any second!
