Timing belt might have broke. Same thing happened to mine. Going to cost ALOT of money to fix.

Don't waste your money on unnecessary sources and unwanted repairs.. get this manual online at www.reliable-store.com u will know whether to repair or not, service it, and how to repair etc

General rules of thumb: Low speed engine on acceleration with smoke in the exhaust plume = worn piston rings High speed engine accelerating (spooled up turbo) with smoke = oil form turbo bearing and/or piston rings Engine on over run (coasting down, foot off the gas) with smoke = oil from valve guides. VW/Audi make good engines with tight tolerances so none of the above should apply at 62K miles; just make sure that the oil (the right oil) and oil filter are changed regularly.

Do not quote me on this one because I do not do much work on audi's but on most of your newer domestic cars the come a safety feature called a rev preventer. This is designed to keep a car from blowing up due to high rpm. I do not know if this is the case with your car, I just figured I would throw it out there. I hope this helps you out.

try ebay or dealership

Yes just remove shaft and old seal and replace new seal with a piece of wood while tapping the wood all around the seal enenlt so you don't damage the new seal. Hope this helps.

Audi recomends intitial replacement at 35,000 then every 40,000 miles. This engine is labeled as an interference engine so be careful. What this means is that if the belt breaks, it could cause engine damage(bent valves).

consult the garage mate, I think you need to stage the torque using a dial guage mate, some thing like 22 ft lb then half a turn but not sure,

replace the thermostat as it is essential for correct operation. Have a pressure test done on the coolant system and check for leaks in the radiator --rear and sides of the engine and in the cabin around the heater core.. Check radiator cap as it may not be operation correctly and allowing the water to be drawn back into the radiator on cooling down. Check the hose from the reservoir back to the radiator cap as if it is cracked or broken the water will not be drawn back to replace what was pushed out when hot. Have a compression test done to check for gasket and head cracks.
