oil pressure sensor ?

  1. #1
    right basically on my mk2 vts my oil pressure gauge on the dash right hand side- just sits at the bottom, doesnt move atall. when i first brought the car it did work, but decided to not work after 3 weeks.... 2years later ive decided to change it. just i cant seem to find anywhere that sells them, ive looked on ebay but it comes up with a few things im just not sure what one is the right one, as all i know is that its some sensor on bottom of engine plugged in with 1 wire.. just wondered if anyone knows where to get them from and are they hard to fit- or is it just a matter of unclipping wire unscrew and then fit back ? thanks adam
