Cleaning throttle body

[Brad.]

I can't find a guide, seeing as its my first time i don't don't wanna f**k it up.
My car feels REALLY sluggish under acceleration recently, which sucks, only started recently and i've read that this *could* be a cause.

Anyway, i did have one on here, but i can't find it anymore.

Any chance someone could either give me a decent guide or some pictures please.
Hardest bit i've seen to so far is actually getting the air box off etc...

"To clean it without removal:

Purchase some carb cleaner from halfords.
Remove your air box
Spray some cleaner on a rag and wipe the throttle body until visably clean.
Get some to start the engine up and rev it up to around 4-5k, pulsing the pedal. As the butterfly flap opens spray the carb cleaner continuously into the TB. Use around a quarter to third of the can.
Keeping the car running, take it for a good spin after to burn off excess cleaner."

Yep, that's it.

The airbox is never a harder thing to remove, just a few screws.

Incase anybody doesn't know what the throttle body looks like, it's here:

this is what you'll find upon removing the airbox,

And this is a clean throttle body:

ahhh interesting

think i might have to give this a go, keep things tidy

Same.
Only thing i'm worried about is having to re-align the throttle body afterwards because i don't have easy access to VAG-com...

I've done it twice to mine now, and to a mates also. And never encountered the problem.

Disconnect the battery for around 15-20 minutes to ensure all power is drained from the ecu, then re-connect battery and leave the key turned to ignition for around 30 seconds (dont start the engine). You should hear some clicking which basically means the ecu is re-configuring the throttle body, after 30 seconds you can start your engine.

The method NFS has mentioned does not work on all engine though. It only works on a select few engine codes.

As long as you dont touch the butterfly valve it will be fine - use wynns carb cleaner spray on it, which will remove the need to wipe it with a cloth due to the high pressure of the can.

^^^^doesnt work on the engine code AUA, had to have my re-aligned due to cleaning mine, was a right pain in the arse, had to keep disconnecting the battery every 30 seconds due to the car not revving at all!
