Dealers do seem to trust their diagnostic systems more than their common sense sometimes. They'd rather replace electronic modules (often at the customer's expense) than something basic.

I’ve had it on charge overnight with my brand new CTEK and this morning the battery was showing a full charge. I hope that’s the end of two weeks of heartache.😀

According to the sheet I've seen for this the Jaguar charger seems to have an additional bit of wiring (apart from the +ve and -ve tags) that plugs somewhere on the left side of the battery? Anyone know what this does - is it a feed into the battery management system? Is it necessary?

As far as I’m aware that’s a fuse. The main thing is to ensure that the negative is wired to an earth terminal and not to the battery negative as there is an intermediate battery control module prior to the negative terminal of the battery which monitors the charging current.
