    Hi Tony,

    I presume as you have the 1.1 it is key start? The handbook instructions below cover all that is required, no programming is necessary.

    Things to check:

    - "Dud" or counterfeit batteries do get into legitimate supply chains. If you have a multimeter, the new battery should be showing 3.3v. Otherwise you could try another new one of a different make.

    - Obvious thing, are you sure the battery was inserted correctly and the right way up? We've all done it!

    - Batteries nowadays often have safety stickers which can leave a residue when peeled off. Use a solvent to ensure the battery contact areas are free from this and fingerprints, etc.

    The new battery is either 'dead' or it's fitted upside down.

    Is your car a 2021 or a 2023 ? 🤔

    It's probably a late 2021-on facelift model (Mk 8.5) registered in 2023.
