Has anyone experienced a malfunctioning oil pressure sending unit?

I had my 3.0 rebuilt back in 2002 by Motormeister in Calif. Have not put that many miles on it since the rebuild . Anyway > when I first crank it up > oil pressure reads normal [1 bar per 1k rpm] when it gets to operating temp though > oil pressure drops. to the point where it reads a tad above 0 at idle. [my right ankle is getting tired rolling over to the throttle and brake in keeping a high idle]..

I was reading on a Mercedes site that oil pressure sending units do go bad - read correctly at low temps, and then fail at higher temps.

I was wondering if this can also be the case with P-car senser units

Bentlys says to check it by removing the sender unit > screwing in a mechanical gauge 22mm threads and using that to determine the oil pressure > I don't have that tool > ergo can not check via the mechanical means >

Should I just buy another sender and check it that way [$56 or so]??

suggestions from the wise-men???
