URS6 Gauge Cluster Turbo Gauge Retrofit

This project is one of many relating to the interior of my 1995 Audi URS6. The goal of this project is to integrate a vacuum boost gauge into the stock gauge cluster in place of the clock. The clock is a pretty intricate mechanism that is connected through a circuit board to the oil temp and collant temp gauges. This makes it a quite difficult job to do, as it requires bridging of several soldering points and avoiding destruction of several traces on the circuit board.

  • Starting point. Stock block gauge removed from the circuit board.
  • The subject: vacuum boost gauge
  • “guide” for drilling hole 1.
  • hole 2
  • hole 3
  • hole 4
  • holey cow
  • holy moly
  • bored out… dangerous
  • I may have gone too far.
  • When clearancing, I burned up a sanding disk, melting some acrylic.
  • A bit more to clearance from the acrylic face.
  • This side is fine.
  • Nearly there. The finish line is in sight.
  • Yes… It’s more crude than I wanted. I was out of step-bit drill bits…
  • I may fix this by squaring it up.
