      If 098 says Error, or Not Available you should have a fault code and the TB is not able to be calibrated. This can happen for several reasons, including the T cable is over adjusted, vehicle voltage is too low, the TB is dirty or faulty, the Ecm is faulty or the wiring is damaged.

      Please post the Auto-Scan from this vehicle.

      Hey everyone,

      Total noob question but found this thread after an uber search.

      Have a wee 1997 Audi a3 1.6 petrol that is now idling at 2000 rpm after I cleaned the throttle body with carb cleaner. I don't see an iacv on this model.

      Would the above process have to be carried out after such a simple clean and is this high idle a likely symptom?

      Thanks
      Andy

      That depends on the use of the mentioned Idle Stabilization Valve (ISV) -or- Throttle Body that's controlled by the Ecm. We didn't get the A3 until the newer 8P body and the 1.6 wasn't available in the US on the other (similar) models.

      Can you post the engine code?

      Hi Dana,

      I will indeed when I get it, had to call it a day yesterday so they are driving the car with the higher idle for now.

      I had a good look for an ISV and couldnt see one on the TB housing, just the wire controlled butterfly part and a big plastic housing on the opposite side.

      When i was playing with the throttle and looking at the tb to see what was going on, i could feel it being pulled/clicked or moved by something, thats what led me here.

      Looking at wikipedia, its the following but ill get the exact code tonight.

      1.6 8v
      1,595 cc (97 cu in)
      AEH/AKL/APF
      101 PS (74 kW; 100 hp) @5600 rpm
      145 N·m (107 lb·ft) @3800 rpm
      1996–2000

      Thanks
      Andy

      Hey,

      Ok, tried to connect it to VAG-COM tonight but it wouldnt connect at all. I just wanted to even check for error codes for a start.

      The car is an 8L Audi A3, still dont know the engine code.

      I also took a few pictures to see if it helps to identify the engine but i see we cant upload them here, not too sure where to find the engine code as it isnt on the vehicle document.

      Where would i find the engine code of the car?

      ANy thoughts on not being able to connect?


      Regards
      Andy

      Hi,

      As per the repair manual this Ecm (Simos vendor) supports the TBA in group 098 as shown on the Wiki page for DBC engines.

      Cable-Throttle Engines

      What are the details about the VCDS system you're using? The Interface model (i.e. KEY-USB), VCDS software version and PC details would be helpful.

      Do any other installed control modules communicate with VCDS as listed here: Audi A3/S3 (8L) ?

      Hey Dana,

      Ok, so in theory this wee car should work.

      Its the basic connection thats not working, it just wont connect at all. Any time i try, the wee window in the top left babbles about baud rates etc etc.

      Not sure about versions Dana, its a skanky looking connector tbh.....in fact the USB connector is rusty

      Most certainly does not look like the £200 ones on your site, its transparent blue etc.

      Regarding the software, I think its 4.09.

      Its OOOOOOOOOOOLD but surely should do the job.

      Thanks
      A

      I have a 2000 VW Jetta, 2.0 NON TD. I was just getting ready to spend the money to replace the throttle body but then I came across this forum. How do I know which adjustment to use and how do i do it?

      If this is a US/Canadian 2000 Jetta 2.0L AEG engine code you would use the Cable-Throttle Engines procedure.

      If you aren't sure, post the complete Auto-Scan and we'll see what's installed.

      Hi, i have a 1997 VW Vento, 2.0 petrol AGG engine.

      What blocks do i need to perform TBA?

      Thanks

      Hi, I've been looking at your post about realligning the Throttle body (I changed my battery and it seems to have thrown out the allignment)
      Your post explained everything, except what tool I should use to do the job. what scan tool would you recommend? I don't have one, and would like to buy one, but I don't want to get one that won't work. Thanks

      How about the company which sponsors this forum? That's the company that Dana works for, and the company which created with site in the link that you thanked Dana for posting. That company makes a tool....

      I cannot manage to reset the throttle position even after the pedal was changed and removed the throttlebody and freed up the spring to close the throttle. should i just buy a brand new throttlebody or change the parts from an audi throttlebody i have? could it be the computer, because before i got the car the kid put an aftermarket exhaust on it and he ended up changing the front 02 sensor.

      So here is the $ 64,000 question. How do we keep our cars running nicely like we had just done a TBA without constantly having to do a TBA?

    17. 11-03-2012 09:41 PM #42
      RTFB or find a professional.

      64K will get you some good service.

      Ive removed, cleaned and reinstallel mk4 2.0 2002 jetta throttle body and ecm,and tcm with no adaptation post cleaning and the car ran fine I did disconnect battery prior to cleaning throttle body and ecm and tcm with electrical contact cleaner ....so vagcom not nessasary!

    19. 05-18-2013 04:28 PM #44
      That I can tell you is a completely ignorant and incorrect assumption.

      RTFB says you need a scanner to ADP the TV anytime it is replaced or the battery is disconnected.

      When your trans grenades prematurely for poor learned angles or kick down.
      Please sir you come on back now ya hear?
      Post your scan later when you finally capitulate.

      Happy trails!

      Hi. I don't know if this thread is still active but i'll give it a try.
      I have just bought an audi a3 that seems to have throttle problems so I figured a tba should do the trick. I'm using a friends vcds which should be 4.09 registered on a win xp laptop. When we try to do a tba as per the instructions on channel 098 we get "bin. bit" in the two last boxes and nothing happened. What does this mean? Are we doing something wrong or is the tb busted?

      If you post your Autoscan that'll tell what modules you have, their current settings, and if there's any fault codes stored

      I posted this over on the 2.8 12 v forum but figured would ask here as well.

      I have a VAG-COM and performed the steps for the TBA. All went well. Problem is, it doesn't seem to take hold. Every damn time I turn the key to the accessory position, I can hear the throttle body doing its little dance and performing an adaption which I don't think is normal. Anyone have any ideas as to why this is happening? Vehicle is a 98 GTI Vr6 by the way.

      Thanks for the help!
