12V battery warning

[Geeman]

On my Cupra Born V3 72 plate I am getting this yellow message after a short while from setting off. '12V supply is currently restricted'.
Manual has other messages but not this one.
As far as I can tell the 12V battery is charged as a battery tester all lights up and battery charger shows its charged. Car appears to drive well and everything seems to work.
Will it keep driving OK?

Any ideas before I go off to the dealer, which is some distance as the local one has just changed brands which is annoying.

Go to the dealer and let them handle it. It could be many, many things and none of them are within the scope of the owner to resolve.

Where is local?

My local one in Letchworth, not actually the nearest but the one I prefer to use, switched to Renault Dacia for Sales and Service about six months ago, but has continued as Service for Seat CUPRA.
