Oil light above 2000 RPM

The 2007 CRD I just bought has the oil pressure light that goes on and off while driving. Usually it turns on at the highway when revving over 2000 rpm, it stays on while above this RPM and then turns off when I slow down. I didnít notice this while test driving it but I might have been too exited to notice it. oh well!

Took it to the dealer and they are waiting for a new PCV and oil cap. I hope this will fix it. Is there something else that can create this light to come on? What about a sensor?

From another forum I posted at

This potrusion is tapered, with an O-ring boss at the end. When I got my '08 CRD, the mandrel was broken. The tapered extension and O-ring boss wasn't there. My oil pressure light came on above 2,000 rpm, as does yours. A new oil filter cap assy fixed it. CAUTION: that light indicates low oil pressure. It's not lying to ya!
BINGO!! Can't believe the dealer did not checked this!! You would think they would check the basic things like filter the filter, right oil, etc. So disappointed!

I was about to do my oil change and this is what I found!

This is the new oil filter housing cap, part number 5175570AA. This fixed the light issue. No more oil pressure light coming on!
