Here are the pics of my TB after the clean: Just for the record, I have no issues with idle, take off etc, I just would like to see the adaptation in action and the result showing ADP OK. Maybe my cheapo V-Checker doesn't do this properly? One thing I noticed was the throttle valve angle (on Measuring block 3 - 01 Engine) was around 3% previously and now around 1.9% on idle so seems to have closed up a little more after the clean.Īnyone have any ideas why my adaptation is performing like this? The video above is after I did the clean.

I put the TB back and it still refuses to do the VAG adaptation. (Pics are below if anyone is interested in what it looks like). I cleaned this thing to mint condition, even opened the motor area and made that brand new too. I decided to take the throttle body off today and give it a good clean as it was a bit dirty and a clean throttle body can prevent the adaptation from taking place.

Now, I'm not particularly fussed with this as I do the manual throttle alignment procedure and my throttle seems to be fine (Ignition on, press pedal for 5 secs, ignition off, release pedal, wait 2 mins before taking key out). I took this video of what the butterfly in the throttle body does: 4th field just stays on ADP RUN and won't go to ADP OK. 3rd field should cycle from 1-8 but mine goes back and forth showing only 5 & 2 (5, 2, 5, 2, 5, 2, 5, 2. 1st field shows around 15 and doesn't move much during the process

Using my V-Checker VAG 202 ( ) I tried to do the throttle body alignment as outlined at Ross-tech ( ): I'm having trouble doing the VAG throttle alignment procedure.
