Parasitic drain on 12V battery

[CarlThom]

If you did decide to go for replacement battery yourself, then maybe go for a battery that offers a five year warranty ?.
The Bosch / Exide units usually do.
This is better than the OEM battery that only comes with a 12 month warranty, which does not hold much faith in the factory batteries at all really .
Although we should even be considering this really on a new car after all !.

Surely, but depends when it was actually manufactured as opposed to registered may have been sitting idle for weeks in China or in your country waiting for orders. That would cause havoc with the 22v battery and may be the root causr

I don't think MG have a clue what's going on, Stoneacre are now entering the 6th week of trying to fix my car now, and still not fathomed out what's wrong with it. In total my cars been in an MG garage for 7 weeks and the car is only 11 weeks old

For anybody who maybe vaguely interested in knowing just how easy and quick it is to locate a parasitic 12 volt battery drain, here is a recent video of somebody who clearly knows what he is doing !.
This should take no longer than a couple days ( not weeks ) to diagnose.
Maybe recommend that the dealer watches this and applies it to your car !.
