Why you should use vag-com to re-set the Throttle body

[adam cupra 20vt]

That's the misinformation we (and this thread) are trying to dispel.....

Ahh! It was in the 1st post.....rather than delete my post I'll keep it there so others can see it won't work

thanks for the info. just done this on my 03 leon cupra, and now seems alot more powerful and responsive after a quick 5 min drive.

initial figures were
14.8% 84.8% 0 ADP OK
after vagcom
14.5% 85.2% 8 ADP OK

is this what to expect as a change?
also anyone in chester area need this doing i'm happy to help

Absolutely catagorically yes you definately do need VAGCOM/VCDS to reset the throttle body.

I've just had a nightmare after cleaning the throttle body on my 1.6 16V Leon. All I got was mega rough running after the clean, with fault codes showing for barometric pressure implausibility and throttle body problems.

I did try the ignition on with the door and bonnet open, and that did absolutely nothing.

I then borrowed a HEXCAN from a Briskoda member, and after 30 seconds with the laptop, the car is now running super sweet. All the fault codes were cleared, and haven't returned in the couple of days since I did the job. I only picked up the Leon last month, and from day one I always said the car did not feel like a 1.6. I now realise just how sluggish it was -- the car now feels much crisper and more responsive. I'm just interested now to see what the fuel economy is going to be like!

Ok so your not supposed to do a TBA with the key in the ingnition?

I thought you did the TBA with the ignition on but without the engine running. Could someone please clarify?

 

[LEE69]

Yeah ignition on and then re-set it

Cheers Lee.

I think posts 15 to 17 of this thread covered that

Have a look at Ross Tech's advert for TBA.

key in, ignition on, engine NOT running, and your foot no where near the accelerator

I was refering to the Vag-Com method.

You can reset the throttle body on mine using the snap-on solus diagnostics tool

i assume using a scangauge would have the same effect as vag-com as i mite be getting one for xmas and it says can do it on there?

has anybody used one to do a TB reset with one?

 

[LEE69]

I think that just reads and clears codes, rather than does the TB reset.

 

[lukecupra2001]

ill look into it but im sure i read the manual for it on the website and says you could do a TB reset.
could you let us know if you find anything on yours,as be handy as i dont have vag-com.

cheers

 

[LEE69]

Mines long gone, sorry

 

[lukecupra2001]

nevermind,ill have to make a few phone calls and do some diggin!
why did you get rid if you dont mind me asking?

 

[LEE69]

Just fancied a change and then ended up with a Liquid gauge, and I'm very happy with it.

 

[jamiebennett81]

Think I might give this a try with all the recent changes and improvements....

 

[lukecupra2001]

sorry my mistake im getting confused!i meant the liquid gauge,maybe getting one but the cube version that can mount like a sat nav as theres a few vag cars in the family and when get a new car it be a vag of some sort.

so let me start again,has anybody used the liquid gauge to do a TB reset?thats were i read about it on there site.

 

[LEE69]

Yeah i have easy to do mate

Just buy one, mental bit of kit!
