I haven't replaced it yet. Is it likely to cause all these problems, or could there be something else going on?

It is very likely the cause of all your troubles, especially with that specific warning. However, if a new battery doesn't fix it, I would recommend a workshop visit to diagnose the error code.

Thanks for the advice. Changed the battery and that fixed it. Cost me 37€!

Yes, that is quite possibly just the key fob battery. Have you tried replacing it? It is a common issue and the first thing you should check. They're not too hard to change yourself.
