Ok so I'm not putting together a step by step timing chain job thread because my projects usually don't follow the same steps as people who need to just fix their timing. Also doing the timing on a 3.6 is complicated job that requires you to separate the engine from the transmission. Some people may chose to pull the engine and transmission while others may prefer to just pull the transmission when touareg people might want to pull the engine. Its really a slippery slope and what needs to be done. Most importantly I want people to understand the process of re-timing the engine. where to get parts and the tools necessary.
The beauty of the 3.6 is that it has remained relatively unchanged since being introduced in 2006. I'm running a 2016 touareg engine on 2006 management.
List of vehicles this might pertain to:
Potential USA 3.6 VR6 Donors
Porsche Cayenne 2006+
Audi Q7 2007-2010
It should be noted that the Facebook page "VW 3.6 VR6 Performance" is useful...sometimes.

Timing Chain Alignment Procedure for 2008+ engines only difference for 2006-2007 engines is the hpfp alignment tool.
This website has an excellent reference including special tools required, locations of timing marks, and torque values but it has so many pop ups and other crap I HATE IT

How can you tell if you need chains/guides/sprockets
Maybe you have a fuel pump check engine light code, a lot of times people will swap high pressure fuel pump, sensors, fuel pump module when itís really just a timing wear issue.
So check vagcom measuring blocks 208 & 209. If out more than +/- 8* you need to pull the engine and or transmission and replace the chains & guides and should change sprockets and even the hpfp sprocket (it suffers wear on the lobe
Here is what Ross-tech says to check: http://wiki.ross-tech.com/wiki/index...3/P1025/004133
P1025 - Fuel Pressure Regulation Valve (N276): Mechanical Failure
Malfunction Indicator Light (MIL) ON
High pitched whining noise from engine when idling.
ECM may also have stored in memory, P0088 - Fuel Rail/System Pressure: Too High.
When found in 2006 to 2009 Volkswagen Passat, Passat CC and Touareg with 3.6L gasoline engines it is possible the HPFP (High Pressure Fuel Pump) / camshafts are out of time.
When found in 2006 to 2009 Volkswagen Passat, Passat CC and Touareg with 3.6L gasoline engines:
Check MVB group  and  with engine idling, if [8 degrees(+/-)] or more the engine is considered out of time.
NAR (North American Region) users can see VW Tech Tip [01-16-05] for exact repair details.
RoW (Rest of World) users may find TPI 2040216/1 helpful.
When found in gas models with a remote battery such as the Q7, P0088 may be stored due to voltage drop issues. TSB 2025746 applies to the NAR market.
