TT-S

[Litcoat]

Alright all,
Just been getting a TT-S after having to let my chimaera go because of health reasons, do these Audi engines have a timing/cam belt or is it a chain? Just trying to sort out as there's no mention of anything being changed in the cars service history.

Cheers Mark

Chain. Keep an eye on the tensioner

As above, it's a chain if it's a MK2 or MK3.
If it's a MK1 then I think it's fitted with the EA113 engine which is a belt.

MK2 is belt.

MK3 (2015 ish on) is chain.

(There is no MK1 TTS)

I thought the TTS were all TFSI engines? FSI (belt), TFSI (chain). OP is asking about a TTS.

My mistake

Yes, she's a 2010 mk 2, so I'm assuming it's chain driven , though I'll say one thing, after having the TVR it's too quiet, there's no rattles and bangs and bits don't drop off, it's just not normal, I take it that's what you get when succumbing to German engineering

Careful.

Oddly enough in the mk2's the 2.0 TFSI's in the standard 2l are EA888 and chain driven.

For some reason the TTS uses the (older) EA113, which is belt-driven, for some reason known only to VAG. The EA888 would easily have been uprated to the 260+hp in the TTS & was newer in design and more efficient. I had a mk2 2.0 l TFSI remapped to 260+ without issue for 4 years.

It was originally called an FSI when un-turbo'd, then the Turbo FSI, then T[space]FSI, before they gave up and called them all TFSI - just to really fk everybody up.

They must have had a pile of them lying around.

2010 is definitely belt driven (I owned a 2009 model for 6 years).

I think the higher powered versions (TTS, S3 etc) stayed with the "old" belt driven engine because it had stronger (possibly even forged) internals and hence handled the power better.

[Litcoat]

Thanks for that, I know the internals were beefed up on this model so I'll get her booked in and get it replaced

FSI (basically) stands for normally aspirated, direct injection petrol engine.

TFSI turbo direct injection petrol engine.

'Fuel Stratified Injection' in its early days was more commonly known as 'Forking Silly Idea' owing to those first engines liking to go wrong quite often.

Early mark 2s use a belt-driven 2.0 TFSI EA113. Later ones did indeed get the 888, chain-driven engine.
