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.

Thanks for the replies.
Local will now be Preston.
As an aside the car was working properly the day before a minor update then not the next day .. coincidence? But yes off to the dealer then wait for a slot to be looked at. Do have extended warranty with it.

Have you got HV battery protection on? Just wondering if the voltage on the 12v had gone a bit low from the update.

I believe battery was charged as when I connected a Ctec charger the battery charge indicator was showing charged. I also did the download, which was fairly quick, with the drive engaged whilst parked.
Went to the dealer who suggested I turn off the battery protection and let the car go to sleep. Earliest they could book it in was going to be January! Left it overnight but it still was a problem.
So decided to do a full factory reset in the car and left that overnight and it seems to have worked. Bit of a pain as you have to reconnect the app and set up the car as to how you want it to function but it is what it is. Pity no simple reboot option. Lets hope it stays this way. Driven it twice to the shops still OK.
