VW/Audi 2.0T Cleaning with Amsoil Power Foam?

[The Critic]

As saaber1 and a few others have posted on here, the VW/Audi 2.0T engines have serious carbon build-up problems due to the nature of a Direct Injection (DI) fuel system.

I want to clean the intake valves and the intake manifold on my friend's 07 GTI. I understand that the BG Fuel Induction service is effective at this task since it slowly mists a cleaner through the air intake tube for 15-20 minutes. The cleaner removes the deposits in the intake manifold and on the valves.

However, would Amsoil Power Foam work just as well? From what I understand, you are supposed to remove the intake tube and slowly empty the can into the intake manifold while the engine is running. And after doing so, you are supposed to shut-off the engine and allow it to sit for a while before restarting.

But couldn't this potentially result in a very difficult restart? I'm afraid to do it since my Saturn becomes extremely difficult to start if I leave any amount of fluid in the manifold.

Thanks!

Seems like all DI engines have this problem. I've read some bad tales about BMW DI engines. Toyota has the solution?? six port and six direct injectors on the same engine, the V6 on the 2009 IS350.

The best stuff i ever used on these type engines is this,its listed as throttle body cleaner but it sure cleans carbon also.

Not sure if its available in the U.S..It comes with a long hose with spray tip to get right down to the far manifold regions and valve areas.
Power Foam is good stuff,maybe you could pick up some tubing and spray it though like the liqui moly.

Leaving it overnight and turning it over with the plugs out seems to be the trick to these type products,always do an oil change after,some does get by the open valves and down into the chambers.
