Prosport Gauge Install: Air-Fuel (Wideband) and Water Temp in my Audi TT Mk1


Another install!

Isn’t fun to have a car in the garage, winter time, when you’re not rushed to make mods… I can appreciate it! So here’s another mod I added to the TT in the past week: I installed the Prosport Gauges!

I got them by mail as they came from Tampa, FL. I was a bit afraid after reading mixed reviews on the gauge’s quality. It’s true to say that the overall plastic and component quality is not high-end, but then again, for this price what can you expect?

So I ordered two 60mm gauges, one Air/Fuel Ratio (Wideband) and one Water Temp. Water Temp? Yes, apparently this gauge is often faulty on TTs and since I don’t want to blow my engine… I decided to “get one of those”.

I first inserted the gauges in the Osir gauge pod. I decided to rotate them a bit, so the reading will be easier from the driver’s seat. Since the gauges are in the middle of the dash, it makes no sense to install them straight… My 2 cents.

Once the gauges were secured in the gauge pod, I was left with the fun part: wiring the gauges with both electricity out of the fuse box and the gauge sensor. First things first, I needed to find where to insert the sensor wires from the engine compartment, through the firewall to the gauges. Found it! See pics below.

Once the sensors were wired to the gauges, the electrical part was left to do. For that, I needed, ground, constant 12v, headlight and ignition voltage. So I took out the dash and fuse box and wired the gauges. See below.

So that’s that! I connected all the electrical wires to the gauges, made some tests and re-assembled the dash. Here’s the final look.

Hope you like’em. The final touch will be a “TT RS” sticker between the two gauges. I’ll make a video of the gauges in action soon.

Cheers
