Hi, I have a 2008 E93 and my oil pressure light comes on after about 30 mins of driving, i've checked that there is no oil leak and the car has plenty of oil, i have had the oil pressure valve replaced but the light keeps coming on, can anyone help at all?

yellow oil pressure light is low level warning, red is pressure warning (the destructive type). id take it to a shop and have the oil pressure monitored with a gauge in place of the oil pressure sensor for the actual reading of it and see if there is an actual issue or if the sensor is bad or theres an actual pressure problem. oil thins as it heats up resulting in lower pressure.

If it's the oil level light it means it's quart low against 7 quarts.
When you say it comes on after 30 minutes that is about the time it takes for the
the oil to warm up before the level will be checked by the computer.
Learn to run the oil Level check from the BC button on the stalk or from
your idrive if you have one.
