2010 A6 3.0T - Upper Timing Chain Tensioner confusion
#11
If you check the part numbers in www.genuineaudiparts.com, the "Q" suffix tensioner is current from 2008 thru 2017 for both the V8 and V6 (3.2L and 3.0L) engines. The "AH" suffix tensioner is current from 2011 thru 2017 V6 engines only (3.0L), but not Engine Code CCAA. Also, there is a large price difference: 06E109217AH for $83.66 vs. 06E109217Q for $217.25 Given this price differential, there must be a big change in the design and that may not work with your engine. Becasue the TSB isn't applicable to your 2010 and the "AH" tensioner doesn't list your engine code, I would stay with tensioner 06E109217Q.

I’ve been wanting to do this, but not sure if I have the time or interest.
Ive done engine swaps, etc, just at 46, I’m loosing interest in turning wrenches these days lol
How bad was this repair? Just wondering if I should just let a shop do it?

I think it's more likely that plugs and coils will need inspection /replacement if they haven't been already.

If I put a price on not doing it again... No higher than $400 for labor if I have the time(but no motivation), or 600/700 if I truly couldn't make the time for it. But for those costs on an Audi, I would expect truly sketchy work that would probably be regretful. That being labor for one side anyways.
When I removed my downpipes to weld in new Flex pipes, I did notice that to deal with the passenger side(American layout) tensioner, the valve behind the chain cover(AIR system?) must be removed to get the cover off. It's optional on the driver side(it is quite a squeeze though).
As for some kind of update to my story here, still doing great in this engine. Just checked group 93 the other day and was still seeing a small negative correction to keep the cams at target while idling, so nothing appears to be wearing down yet.

For 5000, they had better be planning on dropping the power train to change all 4 Tensioners, chains and guides, along with a complimentary change of everything short of headgaskets.
Not even a dealer should be giving that kind of a quote.

Yes, they said they recommended pulling the engine and replacing chains as well... I said the chains don’t need to be changed yet.
My car has 171,100 km on it
...I’m just not sure of what gaskets I’ll need to replace? I’m assuming you have to pull the SC, so I’ll need at least that one, or two, ?? To the OP, what other gaskets, seals etc did you need for this?
thx

For just the 2 upper Tensioners, the gaskets that should be replaced are the cam/valve covers. The timing covers that house the Tensioners are sealed with RTV. Supercharger doesn't need to get pulled.

still around? Did you lock the crank or just camshafts? Does the exhaust cam gear need to be removed at all?
