BMW 320i faulty codes.

[satyakibmw320i]

Hello all,

I have a BMW 320i and I see the below fault codes.
What spare parts do I need to fix these errors:

002B62 - DME Camshaft sensor, intake
004FBD - EGS Ratio Monitoring, gearshift 5-4
002F44 - DME Electronic car immobilization system.

I have attached a screenshot as well.
Please help me on how to get this fixed, and which spare parts do I need to get ?

Thanks,
Satyaki
