MT10-SP 2019 o2 sensor 2 [P0050]

Hello everyone.

I am just looking for 2 hours to find the answer but i cant find anything.

I was cleaning my exhtatus dismounted from bike and somehow i prob damaged my o2 sensor which has faulty heating now so i have to replace it.
I was on diagnostic and i have P0050 oxygen sensor 2 heater.

On parts depot i found its part 11 and 12


And thier codes are for

11: BW88592A1000 (nahrazuje BW8-8592A-00-00)
12: 2CR8592A2000 (nahrazuje 2CR-8592A-10-00)

So do anyone know which is number 2 ? I assume its A2000 which means that on the left side but not sure.

Also if someone can provide me any link where to buy any cross part - i wont spend for original 200€, i would rather do ECU flash if both were failure.

Also only for my info what the difference between these two if there is any? I was wondering to buy this.

Thanks for any help!!
Ride safe!
