I have a 2005 Audi TT quattro roadster, purchased new in 2005. Have had dashboard instrument cluster failure - twice - in 2 years! Fuel gauge fluctuations, coolant sensor malfunction (had to replace coolant sensor to the tune of over $400! Just two months ago), radio turns itself on after I've exited the vehicle, etc. First time instrument cluster replaced under warranty. Car now has 50,000 miles and out of warranty. Additionally, intermittent headlight failure. Idiot light comes on, left front headlight out. Turn off lights, 5 - 10 seconds, turn back on, everything is fine. This also happened about 2 years ago, but on the passenger side. Both times, shop replaced headlight. Now new wrinkle - when shifting gears (2nd, 3rd, 4th, and occasionally 5th) up, RPM's rev, engine revs and it seems to whir before catching gears. Only when shifting up, never down. What's up? …
