Hello All,



I have a BMW X6 E71 N57 engine, I have an issue with the engine oil level sensor. It always show full, when you start car and measure the engine oil level, it start then it goes to max.
There are 3 wires Power, BSD and ground to DME.

I did the following
1. change oil to new and put a new Oil level sensor  still same
2. check all wiring from sensor to DME and fuse box all perfect
3. cut all wiring from sensor and direct to DME and fuse box still same
4. put a new fuse 20A still same
5. drain all oil from sump (empty sump) and check (with engine off of course) still same

I already changed the following
1. Heater plug it has LIN communication
2. Battery IBS it has LIN connection
3. Alternator checked at alternator specialist and says all ok.

Any idea what can cause this and how to fix this

Thanks
