Help needed for throttle body clean
« on: 29 January 2010, 14:38 »
Hey Guys,
Done a search about cleaning the throttle body and i'm reading that this is quite a simple operation with a bit of wd40 and old toothbrush.

Being a complete newbie and inexperienced to the whole mechanic thing, was wandering if there was any step by step guides, tips etc knockin around before I attempt it. :undecided:

Kinda nervous that i'm gonna completely bugger summit up.

Ta in advance :smiley:

I'd use carb cleaner rather than WD40, you can buy a big can of it for £3 or so. Toothbrush will do the trick but best method is removing the entire throttle body, it's only 4 screws, 1 at each corner and you need to unplug the switch and an emissions pipe, nothing else. To refit is the same as removal, 4 screws, 1 switch and 1 emissions pipe and you will end up with a far cleaner throttle body  :smiley:

Plus get a new throttle body gasket, the old one might be damaged on removal.

It's definitely worth whipping it right off the engine for what it takes, you'll be able to clean it much more thoroughly and its easier than leaning over the car whilst you're doing it. Wedge the butterfly open by sticking something against the throttle cable stop as well that way you can get inside it properly. I used some ultra fine wire wool and carb cleaner and it was glistening like new after about half an hours worth of elbow grease.

Hi, im pretty new to this kind of thing but did it myself on Sunday on my MK3 8v.
1. Remove the Carbon Cannister hose on the top of the TB
2. Remove the 4 bolts (5mm Hex Key)
3. Remove the 2 water hoses coming from the bottom of the TB
    (Follow the hoses back and undo the clips to give yourself some slack in order to get to get them off easier)
4. Remove the wiring plug (Took a bit of force but be careful not to damage it)
    You can now fully remove the TB, I decided to port mine whilst it was out (Go here - http://forums.vwvortex.com/zerothread?id=2065316)
    Thoroughly cleaned after and re-installed with the original gasket, needed a new clamp on the Carbon cannister hose.
Hope this helps!!

I did mine a couple of weeks ago, really easy to do!

What problems you having? Irregular idle? Thats what mine was doing, also cut out occastionally when dropped into neutral, gave the TB a damn good clean and problem solved  :cool:
