Hi, this is how I did the vent mounted boost gauge install for £20. This will work on the A3 8p and S3 8p.
This is a work in progress, so I will update as I finish it. I am posting this now as there has been quite a bit of interest in this mod in a few different threads, so I thought my progress may be useful
First of all, credit goes to Mindak, Muzza80 and smurfworth for the idea and help getting the right parts!
Note: to get the nice OEM look, you will need to butcher your original vent with a dremel! If you are uncomfortable with this (like me), you can buy a spare on eBay for a tenner.
You can do this install with the OSIR vent mount, and I in fact bought one. But I decided against fitting it as I don't think it looked that good.
You will need the following tools: a dremel, a very small flat head screw driver, a larger Philips head screwdriver, a hot glue gun and a drill with a 6mm bit.
You will only need to buy this 60mm gauge, others might work, but this one definitely will http://pages.ebay.com/link/?nav=item.view&alt=web&id=400568539743
I chose a stepper-motor driven gauge so I don't have to run a vacuum line from the engine bay, this also minimises the possibility for air leaks.
First of all remove your vent from the car, it comes out easily by getting your fingers behind the trim ring and pulling.
Next pop the silver trim ring off the front of the vent using the small screwdriver, make note of its orientation as it is important!
Next remove all the fins by pulling them out with your fingers, they should all come out without damaging them.
Next disassemble the boost gauge by undoing the screws, and carefully prising back the front trim ring.
Now hot glue the front plastic onto the gauge, then glue and bend the front trim ring back on.
Now the scary part, this re-assembled gauge is still slightly too big for the vent, so you need to crack out the dremel. You will need to do two things; you will need to make the main diameter bigger for the face of the gauge, note that the face is slightly larger than the silver trim ring on the vent, so it has to sit below it.
You will also have to cut a step into the body of the vent to allow for the circuit board. I messed this step up and went too deep. Fortunately the gears still work as I will be using them later
Once that is done, thread the wire though the hole, plug in the gauge and put it in the vent, then clip the silver trim ring in.
I will also be adding a micro-switch that turns off the backlight when the dial is turned off, I will include details on how to do that in the update
This is as far as I have got, I will be installing it next Friday at the same time as an EGR delete and a remap with Darkside Developments. I will update when it is done
Hope this helps, and any feedback is welcome!
