I have an issue with the Oil Pressure Sensor ('09 c4s 15k), at low rpm's the needle dives to dead and a Warning comes up: Oil Pressure Sensor not Operating. The oil level was fine and there is no issue above 1,500 rpm. Porsche will get the car and resolve the issue.

Any other 997.2 owners have an similar issue ?

 

Hm. Well level and pressure are two different things... you can have plenty of oil in the engine, but the pump isn't able to get it circulated due to a bad pump or sticking plumbing or who knows. Of course if the sensor is just not reading right at the low end of the range, swapping that would be the fix.
