Muggy's RS6 Refresh 2020

[Muggy]

I do have a question for any of those that know...how can I test the hydraulic cam followers? This may become very obvious once I pull the cams out for the chain/shoe replacement, but just trying to get my info ahead. Will one be squishy and others still firm after sitting for 4 months now during rebuild process?

Symptoms include on very cold (as in under 35 degrees F) and after several days of sitting, I occasionally get a pretty heavy tapping which sounds like the classic lifter sound. I also have a mild tap all the time, even when the heavy tap subsides after about 60 seconds. Last winter, when I had this issue, I did to an oil change with Amsoil 5w/40 European spec which seemed to help, but still get the mild tapping all the time that I'd like to address if I can make it less noisy.

I also get the clattering sound at 1000-1300 rpms on both up and down throttle...I've been told that this is "normal", but still quite annoying on a modern motor.

Any thoughts appreciated!

That's your cam chain tensioners (de-)activating.
It's actually the chain rattling.

Thanks nubcake...that's what I thought...hopefully new chains and tensioner shoes will help at least a little bit by taking up a slight bit more slack...

Still hoping that I can diagnose the hydraulic follower racket as well, I'm pulling the cams as soon as I have a couple of hours, hopefully this weekend.

Hi Muggy - do you know a good place to get rotors and pads for a 2004 RS6. And do you recommend a certain brand? Thank you

Fortunately haven't needed to do brakes yet....I hear that the Zimmerman rotors are OEM, just without the Audi rings engraved...nistah has a set listed in the FS thread on the forum, not sure if still available but reasonably priced. For pads, I did a little research a while ago, but forget which ones were the go-to's...sorry to be vague, just personally don't have any good info on this.

Maybe someone else will chime in!
