Idle issue after TB cleaned
« on: 30 August 2009, 17:39 »
Hi, new to here :)

I currently own/drive a 1.8T GTI AGU, heres my problem:

My car was running fine at 800rpm at idle, decided to give the TB a Clean and the sensor that goes to the side of it. After the clean plugged everything back up, let the TB reset the position and now when I start it up it bounces around 1000-1400rpm for no reason, checked on VAG-COM, No error codes, body has been re-aligned, won't be the maf as that was not touch and everything was in perfect working order before the clean.

Any help or advice would be appreciated, many thanks in advance!

How long did you leave vagcom in basic settings to allow the TB to re-adapt?

I did it the manual way, turn the key into idle position, and u can hear the stepper motor on the tb turn and once its done it clicks. Reason for doing this is we tried vag com, but it would not allow me to reset the TB, nor would it allow me to change the value of the idle speed.

I've had varying results with that method of tb adaption on cable operated butterflies.. now i just use vagcom. Will it not let you get into block 098 at all? If certain DTCs are present it wont let you in. Are you using the free version?

Basically what happens is this (running vagcom 3112n):

Enter Bank 098, press GO, voltage comes up, press the "switch to basic setting", then this comes up! "Error Group 98 not available"

Just did a rescan of error codes and got:

17973 - Throttle Actuator: Lower stop not reached
17967 - Throttle Valve Control Part: Fault in basic setting (this one not going away)

if you can't clear that code then you've either put the throttle body back together wrong (missed a plug or something), broken something as you were doing it, or done something else to cause it not to close :undecided:

Plugs are all in, it is in closed position from what I can see, but I don't see how I could of broken it... Its all abit strange that it still does it after the manual method.

i reckon you've snagged a wire then, can you get your hands on a multimeter to check you're getting voltage to the tb?
