1.2 Throttle body cleaning guide

[shep0706]

This is my first guide so go easy on me

kit i used..

O-ring seal part number - 03E 133 073

Water based degreaser and some white spirit

1x Small screwdriver

1x Old tooth brush

1x Wire Brush ( a small one would have been so much easier )

and some cotton buds

Firstly, remove the engine cover, start at one corner first is the easiest method and just pull the cover up it sits on 4 pegs and they push up inside the rubber grommets.

( dont have pic sorry)

Once pulled off the pegs lift up gently and then disconnect the hoses from the engine leading to the engine cover.

( No pic again )

Disconnect the plug connected to the throttle body. insert a small screwdriver into the hole and push gently to release the plug.

Unscrew the four bolts on the throttle body.

Now lift off the throttle body, it took some getting off my car, nothing a bit of gentle persuation cant take care of

P.S watch out for the 2 locating dowels and be sure to put them back in the intake manifold

Now you will be able to see the extent of the carbon build up..

Clean as you wish to remove the carbon build up.

You shuld end up with something like this...

Before reassmebling i would advise replacing the o-ring seal on the intake manifold.

now re-assemble in reverse

when tightening the bolts back up i tightened each one a little at a time in an "x" shape pattern.

Now reconnect the electrical plug back onto the throttle body

now replace the engine cover, dont forgot to replace the hoses from where they were disconnected from.

Thanks viking ! how did you get the pics up ?

 

[Viking]

You have to click the picture and open it in your imageshack page and then copy the pic location, rather than the preview page which you had linked to.

Does this help solve the lag you get between the time of putting your foot down, to the time the car actually starts revving?
Thanks!

It definatley picks up alot quicker and runs alot smoother !

i done it tonight. it was proper stubborn stuff to clean off was that carbon. but it does feel a bit more lively for it. however, i noticed the inlet manifold was also all caked up inside. has anyone cleaned that out yet or is it not worth doing.

I had a go at cleaning throttle body too, only done 25k so wasn't too bad just used a rag to wipe it off.

I cleaned my inlet manifold as best i could with the rag (as far as i could reach).

Anyone know if there is there any way of cleaning it?

Where did you get the o ring seal from ? And how much?

 

[smithy84]

i never bothered. just re-used the existing one. it wasn't perished or anything & it runs fine still.

I got it from Dave @ SERE on here, search for him hes brilliant and about a fiver i think (cant find email)

 

[Veyron]

Does anybody know where i will find the EGR Valve? May as well give everything a clean

 

[shep0706]

Outlined in red is the egr valve its a sort of goldy color just, one end is bolted under the throttle body and one other end to the exhaust manifold

 

[Jordanwaterhous]

I just undid what looked like the EGR from the diagram above and coolant started p****ng out.

I'm not saying the diagram is wrong or that you are wrong i just want to know what i actually undid there?
