Car is a 2018 Octavia, would I be right in thinking this is the original battery?

Yes

Thank you. Died on us last night, had a good run I suppose 8 years. Have to get a new one 🙁. I know it will need to be coded in, new to vcds, could I trouble you for the procedure please, would be much appreciated.

Couldn't edit the previous post. Did a search, found a couple of youtube videos. So going to 'hopefully' follow those when I get the new battery.

Are you changing to exact same baterry? If new one has the same parameters all you have to do is just put new serial number....You can use obd11, Car Scanner or other obd readers to code new baterry..

Not sure what choice there will be up here, maybe limited.
