Hello!
I hope that you won't mind me writting in english, because my german is not at it best (reading is so-so, but writting is quite bad).
I have a 2005 320i (N46B20), 110kW, with 197.000km. The car is in very good shape, and it starts and runs very fine, smooth idle and constant acceleration. From time to time, yellow check engine light illuminates (small one in the upper right corner of the display), and it stays on for some time (several days), but it also disapears sometimes by it self. I've bought a OBD reader (Carly Pro).
First time I've got this faults, which I have deleted afterwards:
002EFE
002F17
002F9E
0029F5
After that, I keep getting the following faults (it's a copy paste of a frozen frames - PAY ATTENTION at parameters for faultset 2 and faultset 3):

I'd say, either oil level sensor, or it's wiring is faulty. But, what about that parameters? I know that 524280km is when it isn't able to read km-stand, but 24V suply voltage, and other parameters (temperatures and engine speed)?? I'm a bit confused.
Thank you in advance!
