Help needed! for 3' LCi E90 N43 Engine.

Had misfiring. Scanned the next day w/ following errors:

• 0029CE DME: Cylinder 2 misfire.
• 002AF0 DME: Nox sensor, heating
• 002AF2 DME: NOx sensor, lambda probe linear.
• 002AF4 DME: NOx sensor, electric.
• 002AF6 DME: NOx sensor, lamda probe binary.
• 0030C1 DME: Engine oil pressure regulation, static.
• 0030E9 DME: NOx catalyst, aging.
• 0030EA DME: DeNOx catalytic converter, sulphurized.

Assuming NOx sensor is the root cause (148.000 kms). I kept driving as there was no issue at all. In the mean time tried "forced" cleaning using INPA software. Not sure if it helped or not. Then tried to disassemble the NOx sensor. Could not. So disassembled the connector and re-assembled the connector.

Anyway, ordered a original BMW (Contienental) NOx sensor. Before going to the mechanic scanned the car again with my colleague. Scan done, ONLY TWO errors existing. Rest all errors disappeared!!!!

• 0030C1 DME: Engine oil pressure regulation, static.
• 0030E9 DME: NOx catalyst, aging.

Can anyone of you please share if you had similar experience or any experience with these two errors? What could it be?
What should I do? Seems like sensor is OK (connector had an issue we disconnected & then re-connected - it's gone!

THANK YOU so much in advance!
