It looks like my V6 3.2 FSI engine has a failed chain tensioner (loud rattling). I've ordered a set of upper tensioners for both banks and will attempt to replace them when the parts arrive. Does this link to the DIY section apply to this engine?

If not, is there anything I should be looking for as I have not been able to find a how-to-guide for this specific engine. I've read on other forums that the tensioner failure is common on these engines. I'd like to try just changing just the upper tensioners as Im not looking forward to pulling the engine without a lift to do all the chains.

 

Completely different engine.
You really should bring the vehicle to a European Car Specialist. That is not a engine for a do it your selfer.
BTW that engine has 3 timing chains , 3 tensioners , several chain guides & the transmission needs to be removed for full access.
And yes it all should be done at the same time!

 

Thanks, but I've been working on Porsche/BMW engines since the early 80's. I know my way around but I no longer do that type of work for a living anymore. I have the factory shop manuals ordered and have reviewed parts diagrams, I'm aware of what's involved. And yes in a perfect world it should be done at the same time. But I'm not a shop billing a customer and having to deal with a comeback.

 

I think what M5S5 is trying to warn you of, is the chains can stretch on their own and set off the codes for timing, the plastic guides can get brittle and crack, allowing slack in the chains and/or pieces dropping into the oil pan, and then if the oil changes are neglected you can get gunk in the cam adjusters and then you get timing codes from those parts failures. You might fix the issue you have now and 10k miles down the road get a stretched chain OR broken guide, maybe both. With your background I'm sure you have the know how, might need special tools for this job and I'm not sure if those are rented out by anybody that rents out the more standard 2.8, 3.0, 1.8 etc tools.

 

^ This is why I like my 2.7T.

I won't be saying that when it's time to swap turbos though.

 

To go in there & not do everything is just plain stupid. Do not be penny wise & pound foolish , you will be very sorry. Take it from someone who still make a living fixing European Cars.

 

I absolutely disagree. First, manufacturers moved to chains as the require MUCH less maintenance than belts and they have a considerably longer service life. I raced Porsche 911's, 914's, and a 325I in the 80's and NEVER had a timing chain break. Tensioners yes, chains no. The more likely situation its that I have a tensioner failure or broken guide. My noise is coming from the passengers side upper cylinder bank. If I replace both the upper tensioners and it resolves it then great. If it's the lower guides/tensioners then the motor has to come out anyway. How is it stupid to or foolish as you say to systematically go from easiest/most likely issue to the lets drop $6k to pull the motor route first? If the lower guides fail 10k miles later, then I have to pull the engine. Ok! At least the upper ones are already done. That makes way more sense to me.

 

If you know so damn much why are you asking for help???????????


Go away Monkeygirl!

 

I asked two very specific questions:

1. Does this DIY section apply to the FIS engine
2. Is there anything specific to this engine to look out for

I was under the impression that this was an enthusiasts forum. Audi owners trying to help each other out with their experiences. For example, Pelican parts forum had great tips like failed headlights on 944's were typically caused by failed .99 cent resistors and provided specific replacement procedures.

Instead, here I'm getting responses I'd expect from a Meineke repair shop. When I was a tech, I found out specifically what caused the issue and fixed it. Versus billing my customers for ham-fisted prophylactic repairs.

Nice video BTW, as a certified Audi tech you should probably spend less time googling Jerky Boys and learn your trade. The 3.2 has 4 chains in the timing gearset.

Lol! Go away monkeygirl!?!? What are you 12?

 

If anyone is looking for an actual useful answer, Ive completed the tensioner replacement and the engine is now fixed. The entire procedure has been outlined here:
