Excellent - well done! 2009 Passat CC (2.0L TDI) stalled at an intersection and was just dead! Had it towed to a workshop - I believe it was the throttle body (or technically ASV valve) that was stuck shut so no air to engine?! Workshop cleaned it out but said I would need to get a new one installed later - $$$! I understand the circular gear and semi-circular gear in the body of the valve also wear out prematurely (due to turning the flap coated in all that sticky carbon). I noticed that X8R in the UK sell a kit with stronger carbon-fibre reinforced gears for the DIY mechanic - what do you think of this?

There's always going to be carbon build up, but when it's the wrong way it's hot air meeting the inlet air and forming on the throttle. There's nothing extra going to happen. This is the manufacturers recommended rectification, all other of their diesels are facing the inlet.

I need to clean EGR valve (i think it is dirty), i tried to clean "throttle body" myself long time ago but later on i've read that butterfly plate inside is not good to touch or push, and i was pushing and releasing many times while cleaning, it is possible that i damaged my TB ? Also, i noticed engine temperature gauge is reaching 90 deg really slow and if i turn on heating it goes back to 70...60... degree..

But it is actually used now as a throttle during EGR operation to partially throttle the fresh air intake and pull more exhaust gas from the open EGR valve.
