Fault Codes from o2 sensor change

[T6 driver]

Hi all, I’m at my wits end with codes, I’ve had the bank 1 o2 sensor replaced and have had no luck, these codes are still appearing , any suggestions for help appreciated, thanks in advance

The fault codes actually contain a more descriptive section - copied below:

P2251 >>> Open Circuit​

P0030 >>> Open Circuit​

P0031 >>> Short to Ground (possibly simply no power)​

For now you can ignore P20EE - not likely related.

Wiring problem?

What's the engine code? What year van?
What's the part number? Original VW part?

2016 2.0 , non original part, don’t know part number , its a CXH engine code.
Thanks so much.
