So I want to clean my throttle body
Sometimes when I start the car (DSG) up after it's been cold (often in the morning) it will flutTer the revs slightly in first gear as I'm pulling off before going into second gear.
I want to clean the throtTle body to hopefully cure this, if it doesn't then its something else!
First off, can anyone tell me where it actually is in the engine? Can I clean it without removing it? Thanks
-
It's in the centre in front of the engine block. You'd need to remove it to clean it
-
Is it an easy job to remove rich? Do I have remove anything else to get to it? presumably engine cover
-
Engine cover, lower near side boost hose, throttle pipe, map sensor wire. Maybe some more bits. It's not easy
-
hmm. I'll have to have a deeper look into it. If I do go ahead ill be sure to post a guide

Removing it isn't necessary. The only reason for cleaning the TB is remove the gritty carbon build ups that can form around the spindle area, which can affect the throttle position sensor slightly when it comes back down to the idle position.
I would just pop the intake hose off and give it a clean in said area. Carb cleaner and a cloth and just prop the TB open with one hand, scrub with the other. You'll need a mirror too as the TB faces the floor. Once you've done that, run a throttle adaptation in VCDS and all should be golden again. Oh and do that with the ignition off as moving the TB manually with the ECU on can create problems.
