battery 11.8v at rest after draining,jumping and starting

I checked and the frunk light went off

as an update though - I disconnected the battery, connected it to the ctek and the same thing..... lights 1 to 4 go on, 10 minutes later they go off aand light 5 goes on and "i" error light goes on. Surely the battery must be duff even though it is only a few weeks old?

Mine was actually the glove box light so worth a check!!

It's certainly not impossible. Isn't it on warranty?

Thanks to everyone who has contributed - but yes, it does seem that despite being a month old the battery must be a duffer and it will be replaced under warranty. I guess sometimes the obvious answer is the answer even if it seems it can't be! Hopefully replacement will fix the issues but if not no doubt I will report back with yet more fascinating multimeter banter ....
