This is the VDO 24 volts / 10 Bar gauge that I am using (purchased on eBay). The oil pressure is between 0.5 bar to 6 bar (7 to 87 psi). The original oil pressure switch has a 0.5 bar (7psi) threshold. The thread on it is M10X1K. I found a VDO sender that has a 10 bar max and can accommodate a warning light at 0.5 bar too (model 360-023). I purchased it from www.egauges.com. You will need to run another wire from the sender unit to the oil pressure gauge on the right side of the engine compartment. Connect the existing warning light wire to WK terminal of the sender, and the gauge to G terminal. The oil pressure should be about 3 Bar at idle, 4 at 1500 RPM (choke ON), and up to 6 Bar during driving.
This is the oil pressure gauge (10 bar max).
This is the original sending unit.
