Calm down dude. No need to get angry over a simple comment.

Caps locks in forums is considered shouting, and some people see it as rude. Was just trying to help out, thats all  :smiley:

engine revs measured in mm.. brilliant :grin:

doesn't sound like it's jumping wildly, most likely throttle body needs cleaning then

Post by: topher on 11 October 2009, 20:07
if its faulty, new one from a dealer is about 200 quid. A used one off ebay might cost you £80 or less. Cleaning it takes about 30 minutes if it's carbd up bad. Wire wool works well... need to adapt it after cleaning though (search!)

could be worth getting it on vag-com to see if you have any throttle fault codes
Title: Re: CAR STATIONRY THE REVS ARE GOING UP AND DOWN AND THE ENGINE DOES TOO????
Post by: Grand Master Patch on 11 October 2009, 22:48
Why don't you just start with giving it a clean and take it from there? Stop worrying
Title: Re: CAR STATIONRY THE REVS ARE GOING UP AND DOWN AND THE ENGINE DOES TOO????
Post by: topher on 12 October 2009, 20:19
it might be really carbd up and sticking, or it might be broken.. you won't know until you clean it
Title: Re: CAR STATIONRY THE REVS ARE GOING UP AND DOWN AND THE ENGINE DOES TOO????
Post by: nottsforest on 12 October 2009, 21:15

Title: Re: CAR STATIONRY THE REVS ARE GOING UP AND DOWN AND THE ENGINE DOES TOO????
Post by: topher on 12 October 2009, 21:30
it's been doing it 2 years? :huh:
 
vagcom will scan for faults, log live data from various engine sensors and re-adapt your throttle body after it's been cleaned.

Title: Re: CAR STATIONRY THE REVS ARE GOING UP AND DOWN AND THE ENGINE DOES TOO????
Post by: topher on 12 October 2009, 21:50
the motor needs resetting to it's zero position if it's been sticking. it will adapt itself over some time, but it needs resetting if you want to see instant results.

If your old man has been doin cars for 40yrs why dont you get him to do it if you dont know how to fix cars ? you really need to reset the throttle though after you clean it - vagcom , snap-on , reflex etc etc im sure your dad will know how to reset etc with scan tools

Post by: snap-on on 12 October 2009, 23:22
clean the throttle body , refit etc and make sure car has no fault codes stored before you do a adaption and as you have a 51 you will have drive by wire so reset body . does your dad have a scanner/code reader ?
Title: Re: CAR STATIONRY THE REVS ARE GOING UP AND DOWN AND THE ENGINE DOES TOO????
Post by: nottsforest on 12 October 2009, 23:23

topher says motor needs settin to 0 postion once its been cleaned
Title: Re: CAR STATIONRY THE REVS ARE GOING UP AND DOWN AND THE ENGINE DOES TOO????
Post by: snap-on on 12 October 2009, 23:35
right this is how i done mine -
1 , check for fault codes first with scan tool as you might find another or different problem/fault . mine has code p1297 turbo/throttle housing pressure loss so i cleared code .
2, remove and clean throttle body as shown in pics in the previous posts and refit it
3, use a snap-on , vag com , reflex etc etc scan tool . i use snap-on , plug in set up and go to functional tests in menu and go to adaption . click yes and the throttle adaption will start which the scanner will open and close the throttle butterfly approx 8 times and reset all its values .
4, start car , job done
Title: Re: CAR STATIONRY THE REVS ARE GOING UP AND DOWN AND THE ENGINE DOES TOO????
Post by: snap-on on 12 October 2009, 23:38
if your dad goes to a garage i would imagine they use snap on as most do , colour graphing , solus , modis etc all do the same

Title: Re: CAR STATIONRY THE REVS ARE GOING UP AND DOWN AND THE ENGINE DOES TOO????
Post by: Rhyso on 13 October 2009, 20:28
why don't you ring a local garage and ask them how much they charge??

Labour rates and charges vary across the country so what one pays will not be the same as someone else
