2003 530i BMW !Stop Engine Oil Pressure!

Okay I just replaced the oil pressure sensor near the oil filter housing, and I am still getting !Stop Engine Oil Pressure! Prior to getting that message I also get the OIL CAN icon flashing off and on. I also get on occasions Check Oil Level.

Question, could a bad oil level sensor underneath the car cause the message !Stop Engine Oil Pressure?

I did checked the oil level, and its fine.

your next step should be checking the oil pressure with a manual gauge

Level sensor is not to blame. Measure oil pressure by replacing the sensor on the filter housing with an oil pressure measuring device.

Thank you for your responses. However since I do occasionally get "Check Oil Level" warning, is it possible that 1.) I could have a bad oil level sensor, because the oil level is fine when I check it. 2.) Does the BMW oil pump have a bypass valve? 3.) If it does, do they get stuck, and could I clean it with Sea Foam in hopes it gets unstuck? 4.) Are Manual gauges expensive and how much are they? Thanks

+1 on what Edge540 and edjack said.

I has been documented that sometimes a piece of crud get stuck in the passage leading to the oil pressure switch. If this is so, you will give a false reading on an oil pressure gauge too.

The way to clear the crud is easy and messy. You need to remove the oil pressure switch, put a bunch of rags in front of the hole and run the engine for a second or two. Now clean up the mess and reinstall the oil pressure switch. If you still get the oil pressure failure light, you need to get ahold of an oil pressure gauge and check what's going on. If the light stays out, you've gotten rid of the gunk and fixed your problem.

BTW-don't waste your time with the oil level sender. You've already established that the crankcase is full-not over full I hope.
