Hello, This will make @GazHyde 's hair stand up on the back of his neck.. lol.. sorry Gary. I am looking at adding some extra gauges to my Z3 2.2i. Does anybody have any experience of fitting sensors to the parts of the engine that might help. Gauges I am looking at installing in the 'M' Console are, 1. Oil Temperature 2. Voltage and the last 3. will be a clock. Is the best way for the Oil Temp going to be a sump plug sensor ? If so what is a good one for the VDO gauges ? The electrical Voltage gauge. Any thoughts on where the best connections would be made ? I know its not everybody's thing, but being old school, I like to see a problem before I have the lights flashing on the dash so I can at least try and stop it before it goes fatal. All help much appreciated.
