8P S3 Battery Coding (57 plate)

[_a3sport]

I first noticed I have the fault code below not long after changing the car battery (I did not check before changing the battery). I seen a few threads/vids suggesting the battery might need coded following being changed. I ran through the video below and I'm now suspecting the battery doesn't need coding for my car. Does anyone know for sure?

Have 71 battery charger but get no response
Long adaption is greyed out in CAN Gateway

Note I also now have the following fault codes. I've just tightening the metal pipe going into the HPFP now so hoping this what is causing the fuel pressure codes. Also car runs fine.

Not known the S3 8P 07 to need battery coding in at all tbh, so I'm surprised if that's the case.

Note also checked battery terminals for corrosion and ensure were tight.

That' what I've been thinking since I have none of the options suggested in the video. The two codes below maybe suggest a loose connection, I'll check engine bay/fuse box now
