After a while living with the error message I took the car to change the oil and tested the wiring of oil level sensor. There is no energy on them.

What powers the DME is the integrated supply module that has some shielded fuses. I can replace the module but I'm not sure if this is the problem because seems that the Fuse F01 also power the oil pressure sensor which is working so far.

on ISTA I can see that the oil level sensor is not present as well.

Maybe some of you guys can guide me on this troubleshooting. I'm trying to figure out if a complete software update can help on this or it's a hardware component error.
