TRespect I wouldn't use any additives. Never used any. The vr6 can handle a lot of heat. I drive mine sometimes to 120. No problem. Next oil change get rid of the additives in my opinion.
In my case I will first replace the bushings and drive test. Then change to higher octane fuel SP98. Then go for the sensors if the marbles don't calm down [emoji1]

Roach2012 Thank you for the Links,
The Shifter Rod bushing could the culprit, i will get some audio/video and post it.

I'm pretty sure its not engine knocking or the sensors.
The engine did have two intermittent codes stored P1696 & P1625 which i think are minor and unrelated. i cleared them and will see in they come back.

So far have only used premium fuel (MON+RON= 91~94 in Canada), but who knows what the last owner used.

One other bit of info is that i put in a NanoTech Oil additive 4 months ago. It has lowered the engine Oil temperature to around 80 (from 90) which i feel is good but still a change in the operating conditions for the engine.

How to measure 3.2 V6 timing chain stretch with VCDS.

There are two other issues I'm investigating regarding this noise: variable intake shift rod bushing and knock sensors. The intake rod will start making a noise if the bushings are bad. The knock sensors can create knock under load. This happens to me when I floor it.
As for vcds timing check there are other things to take into consideration before considering the values you see as indicative of good or bad timing values.
Are you running on low octane fuel? If so try to run on a high octane fuel to see if it makes a difference. I'll be chaning the shifter rod bushing (gruvenparts.com) next week and I'll report back.

Roach2012 Hi i have a 2004 3.2 VR6 Touareg 174,000KM
I can hear the rolling marbles o-death noise from the back of the engine, however when i use the VCDS (OBDeleven) value 208 & 209 are both -4 Deg KW.
could this mean its the tensioner ?

TRespect Update: Rolling marbles are audible when RPM is around 1500 or high load 5000+
I will either get the updated tensioner or the manual one.

TRespect And like I said in the other thread I came across a manual chain tensioner :

If the noise comes back I think I will go for this manual tensioner.

TRespect I just tested the 208/209 measure blocks with vcds. I get -5 on 208 and -7 on 209.

TRespect Pasting a copy of my post in another similar thread:

I finally got to the tensioner. I removed the air duct and was able to locate it. I checked if the tensioner was torqued correctly using a torque wrench. I then removed it. I cleaned it and I was able to empty it completely. It gave in easy, oil was a bit dirty. I did an oil change recently (less than 2000km). I soaked it in oil and pressed it several times untill it was impossible to retract it anymore. I put it back, torqued it to spec (40nm) and surpriiise the rolling marbles noise is almost gone. There is a very faint noise sometimes but nothing compared to how it was before. Some pics of the operation coming later
