Just cleaned the throttle body on my 1.8T AGU. I must say if yours has never been done it its a must!! 15 min job and the engine is so smooth through the gears now :wink:
Ive got some after pics but forgot to do any before as i got carried away with the cleaning :grin: LOL But believe me it was BLACK and full of deposits!!

Did you put a new gasket on after cleaning the Throttle Body. I think mine needs to be cleaned. Did you disconnect battery before taking it off?

No,Because you dont need to replace the gasket. No you dont need to disconnect the battery as there is only a sensor plug which you just unplug. :wink:

Thanks for the reply richw911. Will have a go on my days off.

They say you need to re-allign the throttle body with vag com after youve taken it off for a clean

If you read the link i put up it says you CAN re allign it using vag-com if you have it, BUT YOU DONT HAVE TO.
Because the ecu will reset itself after 20 miles, Ive spoken to three other people who have also done this without the need for vag com. :smiley:

Great post - and I want to do this very soon. Aiming for this weekend!
Have read the link to the other forum that shows details of how to do this task too and there is some debate over whether you should be able to move the butterfly on a DBW engine, since it is controlled using a stepped motor.
Some say its ok to "force" it in effect, others say to get someone to sit in the car, with ignition on (but engine off) and to press the throttle so that it opens the butterfly so it can be cleaned.
What do you guys think, and I want to do this, but dont want to screw up the throttle body! I have a DBW engine, AUM.

BUMPing this post.
Anyone got any advice on my post above, regarding cleaning throttle bodies on DBW cars? :undecided:
Hoping to do this task this weekend, so any advice would be much appreciated.
Sorry to BUMP it - not trying to resurrect the dead! :evil:

I would get some one to sit in the car and put there foot on the throttle tbh mate. Why force it if you dont have to? Defo worth doing this my car drives soooo much better now :smiley:

any 1 know how to clean throttle bodies on the 1.8 20v n/a plz needs doin!! cheers
-
I did this on my car today and also sorted the boost problem out (turned out to be the chip the tuner put in my ecu)
-
lo lads! i done this on my car today but i dont no if this is normal, When i drive a 2k/3k and take my foot of the throttle it seems to hold the revs and drop very slowly is that normal?
my throttle was black! just want to make sure this is correct or i may have to take it back of again :P

Thanks for the post on the throttle body clean
Cleaned my TB today on 1.8t agu engine. All went well, it was filthy! I don't have access to vag com so I just took it for a drive bout 30 miles hoping to reset however it now idles @ 1400 rpm... sometimes up as far as 1600. Has anyone else had this problem? Theres a major improvement in the smoothness of the drive now just the idle problem still remains :undecided:.
Any suggestions?

Mines an AGU. Have had no probs with it since. The engine will idle higher when cold (im sure you know this :evil:) does it do it all the time?
-
Yea it does it all the time. The reason I cleaned it in the first place was to see if it would stop idling at 1200rpm now its worse :huh: Do ya think it could be the MAF? I may go to a garage n get it plugged into a comp n see if any faults pop up..

I think he want to check for fault codes for a dodgey maf sensor :smiley:
-
Looks like a new throttle body is on the shopping list.. even after realigning with vag com the faults didnt clear. Anyone know what kind of price and wheres the best place to get one?
-
I was quoted £150 from VW.

Im going to try this tomorrow
So its garanteed it wont idle high if i clean it. I dont have VAG.com anymore. Just want to be extra extra sure :evil:

No not guaranteed For some reason some lads had trouble with theres??
Put it this way did mine 1.8T AGU and was so much better after, And had no issues with idle probs at all :wink:
-
Nice one! I dissconnected the battery and didnt need vag.com
It was clogged but nothing to effect the running i dont think. Worth cleaning though.
Alot smoother once I cleaned out the sensor pointed below (cant remember the name)
(http://img.photobucket.com/albums/v104/sat1s1ngh/tb4.jpg)
Used electrical contact cleaner (none flux one) and carefuly cleaned it with a cotton bud. Way smoother :cool:
Engine code: AUM

Good job mate :afro: defo worth doing isnt it!! :wink:

For anyone needing to adapt their DBW TB, open bonet, open drivers door, turn ignition on(but dont start engine). DO NOT TOUCH THE ACCELERTOR! You should hear a high pitched noise coming from the TB for about 30 seconds. Once this stops you are done. No need for VAG COM.
This deff works for my 2000 AUM but I undertand that for some newer cars it doesn't. Seem to be a random thing.....
HTH
