    Thread: 98 Beetle Throttle codes

    1. 01-20-2009 12:27 PM #1
      Have a 1998 Beetle 2.0 that I can't clear to codes to calibrate a reman throttle body. Codes are:
      01165
      17973
      17988

      As I try to clear them they come right back and as a result am unable to successfully complete a Group 98 calibration sequence. Have disconnected battery overnight and connected + and - terminals to discharge memorry, but as soon as power is applied, we go straight back to these codes.

      Help!!!

      Tried again and still no luck making it work. Got the CEL off for about 30 sec and then the codes all came back!!

      Please post a COMPLETE AutoScan along with the EXACT procedure you are trying. Clearing faults does not repair the problem that caused them.

      Do you have the full version of vag com? It looks like you may have a faulty throttle body but it might just be dirty. Clean the inside of the throttle body bore with carb cleaner and then run basic setting 98 and see if it passes. If it doesn't pass you probably have a faulty throttle body.

      It is a new TB. The car had been jump started and the termials were reversed! We've replaced the trottle body with a known good one from another 1998 with a matching part number. Using Version 311-2, and using group 98 as it is a cable, NOT drive by wire, car we did the following:

      1. Diconnected battery. Left overnight.
      2. Cleared ECU by grounding battery cables.
      3. Reconnected battery.
      4. Plugged in Vag-Com
      5. Ran adaption group 98

      Adaption failed, but CEL light OFF. Drove car approx 5 miles No CEL. Parked car. Restart about 90 minutes later, CEL back on and same codes. An attempt to clear codes will bring them back almost immediate.

      Since the battery was jumped backwards, most likely the ECM is smoked.

      But verifiy the new/used module is completely clean
      and
      remove the throttle cable from the module (to eliminate the possibility that it may not be at full rest position) and run adapt again, see if it passes.
      also
      battery voltage is important, make sure you are adapting with 12.6V or more.
