I have a 2009 Audi TT with the CCTA 2.0T TSI. The car runs fine (32,000 miles on the odometer), but I've become paranoid about the infamous timing chain tensioner. I've read horror stories about it failing with zero warning, i.e. no MIL, driveability change, etc. If that's the case, then it seems I should have the tensioner replaced before driving another mile. But is that really the case? Or would I get some warning and at least have time to pull off the road and have the car towed?
Hi there, I bought a 2009 Passat with the CCTS engine from the auction, vehicle was in perfect condition, except the writing on the windshield,
"ENGINE LOCKED". I basically knew it would need an engine or a lot of work. When I picked up the vehicle, I checked the engine, it was locked up.. however there was some play, but it would not turn more than 20-degrees or so.
Here are the fault codes from the vehicle as I received it:

If you notice at the bottom of the 's fault code list, the Readiness, is all [0000 0000] - meaning no one cleared the codes after the engine has failed. So what you see is what the customer would have seen just before catastrophic engine failure.
With a bunch of misfires, I am sure that check engine light was on, saying check me out!!! but they must have just ignored it. Too bad because the vehicle had 100158 miles on it when I got it, just out of warranty.
If you find the P0016 fault code and/or the P0341 fault codes in a chain drive engine, neither one of these fault codes should not be over looked.
Also, if you suspect there could be a timing chain/adjuster issue, please see this Ross-Tech forum post:
Audi Volkswagen - 2.0L Chain Drive - P0016 Cam/Crank correlation check
Hope this helps,

ps.. Yes, that is the broken intake valve that is on top of the piston from that CCTA engine. My son and I fixed the damage to the cylinder head and it has been fine since
