Aircraft type: Messerschmitt Bf 109 E-1, E-3, E-4
System affected: Oil Temperature Gauge
Description of the problem: The aircraft measured the temperature of the oil in two places: where the oil gets into the engine, and where it go out. This temperatures was measured with a combined instrument, in which shows the outlet temperature of the oil, but there is a button (upper right corner) by pressing the inlet oil temperature can be checked. This is missing from the game.
The Oil and Water Temperature Gauge is connected to the A8 switch.
