Looking at buying 1st gen/Mk1 TT-what are known issues?

Have owned and maintained a 2008 S6 for last 5 years and a 2009 A4 for 3 years before that.

Considering buying a 2001 TT Quattro coupe 225 turbo 6 speed manual from a trusted friend. He and his family have owned it since new. I know very little about the car at this point, but he is sending me a copy of all maintenance records. We’re also having a PPI done by an independent Audi mechanic.

What inherent, known issues are there with this model? Want to know what I should pay special attention to in the records and PPI.

Thanks.

Those are timing belt cars. Make sure that has been done along with the water pimp. The tensioners and belts need to be changed about every 60k to be safe. some cars went as long as 100k but almost all at that range had timing failers.

The turbos were generally good on the 225 but that will depend on the oil changes. Obviously the same things that you would need to change on your S6 like plugs packs filters are the same. Just no need for a CC clean. Get a compression test. 180+ is a healthy motor.

Great info. Thanks for replying, Justin. Wasn’t sure I was going to get a response over here.

The big issues are the timing belt maintenance and stopping the oil leaks with that engine. The timing belt requires going thru the passenger’s side wheel well and dealing with the side engine mount. The valve cover gasket and the camshaft tensioner seal/half moon tend to leak oil onto other things like the rear coolant flange and ECT sensor causing a coolant leak and killing the sensor. The fuel injector seals also don’t like hot engine oil either. Make sure you change the engine oil often and use a quality oil since those engines had issues with sludge buildup ruining the engine. Generally if the oil pressure light comes on then run away asap.

Since it basically is a VW Golf the chassis has similar issues like the strut mounts collapsing, the struts failing, mounts failing, etc.

Great, great info.
Thanks, Jimmy!

Re: oil change intervals for these cars, do you recommend every 3000, 5000, 7500?

Also looking at an 2002 TT 225. Supposedly has a bad clutch at 132k miles so I can’t road test it. Would the flywheel typically need to be replaced at this mileage or at least resurfaced? Anyway I can get a sense of the drivetrain health? How problematic are these Haldex systems?
