E92 New ECU Coding

[bmw9x]

Hi Guys,

I have a BMW E92 and my ECU got flooded. I've bought a new ECU and installed it to the car.
Would someone be so kind and guide me on how to properly program it to the car?
The car starts and drives, but I do have weird issue with it.
I've tried coding with various tutorial, but with no luck..
Currently My lights are working but sometimes flickering and the high beams not working at all, also the driver side window switch doesn't do anything, but passenger side one works just fine(using the key I am able to lower the window up and down).
DCS also doesn't work.
I've tried coding with NCS-Expert and WinkFP but with no Luck.

Thank you in advance,
G
