Thanks Jon! I am still digging here... got a few enquiries running now for custom VDO gauges that match the factory ones as much as possible. If only I knew someone at MMC who could get me more detail on their gauge supplier for Plus 4 GDIs... Anyone know anybody? I am sure there would be a significant demand (me looking for Voltmeter and Oil Pressure gauge).

I am getting closer though. Found the VDO SingeViu 52mm gauges (oil pressure gauge, Voltmeter gauge both with CAN bus and analog electrical connection!) which seem to be the factory ones, and just need a few changes to individualise the looks.

I also found the exact matching chrome bezels - and by the way: those of you who would like to change their bezels to black or gold (both 100mm and 52mm), check out that website!

So all I need now is to find somebody who will "paint" the gauge elements that would then match the factory ones...
