Hi All,

Apologies if this has been posted in the past.

I have a 2011 Audi A3 2L PETROL TFSI Black Edition and wondering if it is a cambelt or timing chain? After doing some homework, it seems its a chain to last the life of the car but one garage did a reg check and said a belt. Apparently the checker gives 4 engine codes, but most garages are saying chain. 

Any ideas? Is ringing Audi direct the best choice? I don't get why i'm getting multiple answers :/

Thanks!!

Hi William I'd ring Audi in my opinion. I say this as I know the VAG group had to change from chain to belts as chains were stretching and failing when they shouldn't have been. 

Cheers

The V6 's had chains for life unless the tensioner failed

The others had belts

don't wreck the motor for a belt

2.0tfsi is chain 

Thanks a lot for your help!

Hi

My experience is with the 8P Audi A3 TFSI 2007 this has a cambelt which drives the exhaust cam.

On the other end of this cam is a sprocket (vvt adjuster). 

This has chain which then drives the inlet cam, so has both.

If you have both on your model the chain has a tensioner which on my model can fail. So when you change the belt get the tensioner checked out on the chain.

If it fails - its very very expensive!
