    1. 01-25-2009 01:24 AM #1
      When they plug into the car it say error it will not pull the code.
      I dont know what to do sometimes the check engine light is on and sometimes its not. Is there some fuse that could make the port not work or something please help me thanks

      when you say "they" you mean? try another diagnostic device.

      This would be my guess as well, an OBD-II scanner will not work on a 1995 you need to go to a dealer, a VW shop, or use VAG-COM which will be able to read the codes.

      Pull your radio and check if you have a radio wiring harness (Metra, Scosche etc.).
      On the black connector, find pin 3, this a Blue wire, but may be Blue/white.
      This is usually attached to pin1, cut the wire on the aftermarket harness and tape/ crimp a cap on.

      Manche VWs sind einfach schneller als andere.

      Well let's go a little further. If the diagnostic link connector doesn't have power you will not be able to blink codes, because it has no power! Like I said, the power for it runs off the cig fuse. Find which fuse it is and replace it! You take it to a shop and they will most likely charge you too much to replace a fuse. Trust me, I work at a shop and see this happen too much!
      Fuse position 22, pull it and replace it, 10amp

      those BS parts-store scanners don't read 95 VW's even though you have an OBD2-style connector.
      You have to use a proper vagcom diagnostic tool & software. Post a thread in your regional forum asking to borrow one and I'm sure there will be people who can help you out. [IMG]http://*****************.com/smile/emthup.gif[/IMG]

      the 95 jetta is hopeless right now. i plug the jumper in and it resets the CEL light every time i did it correct it treats me so bad right now

      You are going to need to check for power and your going the worng way about it..
      At the end of the plug #16 is power take a test light and see if you get power. Make sure you get ground as well. Then if you are, check behind the fuse box that this wire is connected, its the yellow and gray wire..

    20. 01-26-2009 08:44 PM #20
      defroster button works well my friends

    21. 01-26-2009 09:03 PM #21
      On the side of your rear glass will be to clips one on the left side and one on the right test them and see if you have power.....
      Whats going on with the data link do you see if it is getting power...

      well thats all thats left when they plugged into it. with there machine it did flash so i think it isnt getting power bc the cigarette lighter isnt working

    23. 01-27-2009 06:05 AM #23
      keep in mind that obd data link powers up the scanner. Listen just stick a test light at the of the obd port slot 16 im tellin you have power....

    24. 01-27-2009 08:51 PM #24
      ok i will get a tester light tommorrow and see if it has power for sure. but the cig lighter doesnt work and i think it powers the obd tool as well
