I don't recall what years have this, but later models have two sensors -- one is the 0.3 bar that illuminates the dash lamp if the pressure is lower than that.  The other is a 0.9 bar that triggers the buzzer if the pressure is too low above 2000 RPM.  I think the 1.9 on WBX the '84 only has the 0.3 bar but not sure about that.

I'm not sure what a 1.8 bar sender would be for.  But I do know that someone had installed a 1.8 bar sender on my 2.1 WBX causing the buzzer to sound unnecessarily; that problem went away when I installed the correct sender.
