CAM chain tensioners failing..... TSI engines.

[Transporter]

I also laughed at number 7, the engine has exceeded the maximum engine revolutions...... with all the computers in cars these days they wouldnt stand a chance with that either if you had proof that the engine was standard and the ECU was untouched.

This is also something that a second owner needs to be aware of, and they should treat every performance car sold as a second hand as it had/still has the performance tune and even being a low km car still under the warranty, it still could mean, that you have NO warranty.
Basically you're in a mercy of the VW Au and their goodwill warranty if they feel like they want to contribute to the repairs - most likely NOT.

I have 2010 Golf GTI as well as the Tiguan. I havent heard the rattle in my Golf, bought it a couple of months ago second hand.

Wonder what the odds of VW taking a look at it even out of warranty for the tensioner issue.

The fact theyve got a fault number for the Skodas, the more I see this thread, the more I feel a possible recall from vw coming along.

Just a quick update.

Got my Tiguan back after 2 days at dealer. Chain and Tensioner replaced under warranty no questions asked after they also heard the rattle sound on start up.

Sound is now gone completely.

Also - I do not get my car serviced at the dealer, had no issues with warranty.

Finally had time to go under the car and capture that annoying noise. WasteGate Rattle or something more serious?

At the end of the video when I put pressure more quickly, you can hear the bike chain sound.

Have you had the dreaded cam chain tensioner looked at / replaced? A known issue with 2010 & previous that i personally am a victim of...

[Suffolk]

I guess I will have to take it to my mechanic as my warranty just ran out.

[tigger73]

Definitely doesn't sound like waste gate rattle - get it looked at and if it's a known issue you may still be able to get it covered under warranty.

Does anyone know if there is a 5yr warranty on powertrain ? As my 3yr warranty just ran out I'm afraid of the cost to fix this problem.
Also was told maybe the engine may need to be replaced? If it's the chain tensioner.
