Question about BMW X5

Messages of "oil level low" and "Oil level sensor defective" show up when turn off the truck and take off the key

My BMW X5 4.4i with a N62 engine has 81000 mile. Everything is fine except for the messages of "oil level low" and "oil level sensor defective". The messages come out sometimes when I drive the truck for around 15 miles, turn off engine and take off my key. These messages and "oil presure low" warning light never come out during driving. I did some inspections: oil dipstick shows that oil is full when motor is not running; oil dipstick is dry when I start engine. When I stop engine again and check oil level immediately, oil dipstick is dry. 1 min later, the oil dipstick shows oil is full. I think that the oil level sensor is good. It seems that the pathway of oil return to oil pan is limited for some reasons. I would appreciate if you have any suggestions.

You need 3 basic principles for your vehicle to start fuel/air, timing and spark. You stated it seems like there is no ignition at all. First, I would pull the easiest spark plug attach the plug wire and set it on the manifold and have someone crank your vehicle with you watching the plug to check for a spark you should have a white/blue spark which denotes a high voltage. Next i'd check for fuel pressure, if you have both i would get a obd (on board diagnostic)scanner and check for trouble codes with koeo (key on engine off) if that doesn't produce any codes check your fuses and most importantly if your oil level on the dipstick was dry its going somewhere whether its a leaking gasket a crack in the engine or blow by figure out where

Try checking the engine oil for correct level, the low oil sensor will disable the ignition if it is more than a quart low

Engine is running fine. Oil level is good. Oil light comes on and off at random. Engine isn't knocking and runs great. Recently changed to GTX extended milage oil. Problem developed

The oil light comes on when the oil pressure sensor detects low oil pressure. The amount of oil has little to with it, although very low oil levels can cause loss of oil pressure. Since you aren't getting knocking, chances are the oil pressure sensor is defective. Replace it and monitor the situation closely. This could be a serious condition if allowed to escalated and it turns out to be an oil pressure issue.

Oil pressure light comes on?

You must immediately check your engine oil level and take appropriate action: unless you have a defective oil pressure sensor, oil pressure light usually indicates that your engine oil is not flowing properly. Some possible issues: low oil level (leaking engine?), blocked oil filter (when did you last get your car service) or defective or blocked oil pump due to excessive dirty engine oil.
Hope it is of assistance.

For 2002 BMW 325I a yellow oil light comes on when engine first starts and sometimes at random times then turns off a few minutes later. All oil levels are good. Not sure what this means and how to fix it?

The oil light does not show that you need oil necessarily. The oil light goes on when the oil pressure is low, not the oil, so it could be a problem with your oil pump or otherwise. Common that it would go on and off, it it were to stay on for very long you'd lose oil pressure and could be in trouble. Have it looked at.

Good luck!

I need sensors (master reset)

Open the DIS [Driver Information System] with the car running. The screen should flash all the annoying messages. Press the "Fuel" button repeatedly until the messages clear and it displays your fuel used. The press the Eng button until it shows your Oil Life, then hold down the reset button for 10 seconds. Then press Eng again till it shows your Transmission Fluid Life, and hold down the reset button for 10 seconds. As for the coolant indicator, make sure the reservoir is filled to the appropriate level. If you still get the Low Coolant message, check to make sure the coolant level sensor is plugged in (its on the reservoir) and if it is, then it may need replaced or cleaned.

Oil fill light

i am pretty sure the oil light comes on when the key is turned to the ON position, then goes out after it starts (providing oil quantity is not low). if it stays on after it starts, then may be an issue with sending unit.

mention it to the dealer when you take it in and they should be able to further diagnose.

BTW, what service is it going in for is oil service was performed 5000 miles ago?
