UK-POLOS.NET - THE VW Polo Forum

hi. went to volkswagen today because i had some problems with the revs jumping up and down and acceleration not being normal. VW said i need new throttle bodies and on top need a new pedal box. they are asking for £350 just for the part. any help on where i can get it cheaper????? thanks

Banter with them, you may be able to get the pedal box done as a goodwill gesture, as there was a re-call for all GTis on this part because of a weak weld.

You might be able to. Try the dealership out - its at their discretion as its warranty work

Are we talking about a markIV?

thanks. yeh its a 6n2 1.4 s not a gti. i already tried it they said they only did the recals to a certain period of time and they only did it on gti's. any help on the throttle body????

No chance the throttle body can be cleaned, personally you could do it yourself and change it if need be, ive heard for our throttle bodies best thing to do is soak it in petrol
many thanks

Can of Carb Cleaner does the job

Tim's right. can of carb cleaner did do the trick. now it starts and runs like a dream

Sweet, mine could do with a good clean also actually.

never spray it into the throttle body always put it on a rag and wipe it out as it can f**K the sensor up thats inside

Since when? I've always sprayed it in whilst someone else revved the engine for me to make sure the engine doesnt flood.

hi tim i also want to clean to TB for the first time since i own the car (92000 KM)

i want to disassemble the whole TB any clean it properly
i also have a vag-com cable and laptop

but doesn't sure about how to do this.
1.there is any guide with pictures on 6n2?
2.the polo tb known as a very sensitive tb - it won't cause problems ? after all it's not a cheap part.

what bigger VAG tb can match to my 16V ?

sorry for so many qeusions.

thanks

Well the way i do it is remove the air filter/box whatever you have, exposing the TB.

Give it a wipe down with a cloth soaked with carb cleaner. When it's sparkling start up the engine and get someone to pump the accelerator, peaking to around 5-6k. When the butterfly opens on the TB spray the carbcleaner directly into it. Use like half the can, and make sure the friend keeps pumping the accelerator. Take it out for a good spin after this.

nice before and after pic

but it's now quite clean unless you update the ecu with scanner or vag-com


the TB need to know shes clean
