    Thread: 2003 Passat W8 electrical problems

    1. 07-07-2009 02:46 PM #1
      Hey Lads


      I have some trouble with my VW Passat W8 4 motion, 2003.

      When driving I’m exercising electrical fadeouts:

       The top row, where the radio station show, goes blank

       The multi steering wheel (radio volume up/down, change channel and cruise control) stops working,


       Windows up n’ down stops working

       Finally the AC stops blowing cool air. On the display of the AC control units left, the temperature goes --.

      It feels like a loose connection!?

      It will go on and off 10 times during a 20 min ride.

      The easiest way to tell that it stop working is to look at center display in dash. The radio info will disappear and the AC stop blowing cool air and Florida is pretty hot right now

      To top it off my fuel gage doesn’t work. I did buy the car with this defect but the dealer fix it but a few months later it stopped again and all the above came along. My friend has a VAG diagnose and we did a fault search on the car.

      Below is the list.

      I will appreciate any comments!!

      Thank you!!
