Audi 4000 Oil pressure guage and the dual sender unit

[ralexander03@snet.net (Rick Alexander)]

Rolling Roc (10K on rebuilt 1.8 16v with new 2.0 pump) is experiencing this
exact same thing with a dual pressure sender from a Cabbie. I put a single
sender on and the pressures were more what I would want to see. I put the
dual sender back in and am living with it. At least I have a relative sense
of what is going on. No buzzer no worries. I hope! LOL
