I have attached the directions from the PDF E92 M3 manual.
Using this method you can force another oil level reading without
turning off the engine. If stopped on a level surface the updated reading will happen in about 1 minute, faster than shutting down the engine, opening the hood, finding a towel, pulling a dipstick, cleaning the dip stick, and using the clean dip stick to check the level. I would shut off the engine if oil needed to be added or you will have a big mess.
You can add 1/4 quart oil (engine off) then restart and force a Quick Measurement with the vehicle on level ground in about 3 minutes with a warm engine.
I've attempted that in the past but I've come to realize the system is flawed.
It will give you the same reading 3-4 times and then 2 weeks later it jumps up to full.
Since then I've told my tech to drain for 10 mins and add 8.75l and forget it.
