OIL PRESSURE

1999 Porsche 996 • Automatic • 72,000 miles

My oil pressure light comes on at very low, idle rpm.

when the engine is first cranked, cold, oil pressure light is off. After engin heats up, 150 degrees or so, light comes on at idle. Also pressure indicator shows low pressure. But at anything above idle, light goes out and needle shows good pressure. Local repair shop seems plexed?

Check the oil pressure with a mechanical gauge, if normal replace the oil pressure switch. If abnormal could mean oil pump and engine bearings
