Where is the ODB code reader connector on 1995 VW Cabrio?

Answer 1

Yes. Next to the ash tray there is a black slide off plate that reveals the OBD I plug. {1996 and newer can be read with an OBD II reader (read for free at Advance auto or Auto Zone)} Once you reveal this plug on the 1995, you can plug in a single jumper wire (or even a paper clip) in the #4 and #15 pin hole. There are two rows of pin holes, count from the upper left to the #4, then on to #15 (which will be the second to last pin hole). Turn the ignition switch on (motor not running), insert the jumper wire for about 3 to 5 seconds, then remove the wire. The ENGINE LIGHT will flash a hold, then the code, which will go something like this, flash, flash, PAUSE, flash, flash, PAUSE, flash, PAUSE, flash, flash, flash, flash. Then it will repeat the codes if you just sit there and observe it. The code in my example would be a 2214 code.

Below are some code I found on a website. Now I ask that you take the time to answer someone elses question. Lets all share. Good luck, "Peace through power and knowledge"
