Good evening all,
We took delivery of our brand new Piccadilly Blue MG5 in March earlier this year (FL model).
We can honestly say that it surpassed a lot of our expectations both in range and charging speed.
However, in May the car developed an issue where the 12V battery drained more than 0.5V in 24 hrs (as shown in the app). MG Poole (where we bought the car) was informed and the car went in at the earliest opportunity (which sadly was 1 month later so around the 30th of May.
At the same time it was also showing the “U Disk identity Failure” Which was also passed on the MG.
They handed the car back the next day and everything seemed fine.
About a week ago, we got the “U disk identity failure” again and consequently the battery drain came back. Thinking the 2 were related I disconnected the 12V battery (as suggested by this forum). This fixed the problem until yesterday.
After an overnight charge and a 160 mile round trip the car was showing 11.9V this morning which has dropped further to 11.6 this evening.
The car will go on charge tonight as we could not charge it last night due to some issue with the charger (Ohme Pro and not related to this regardless whether it’s connected to the charger).
Has any of you come across this issue before? And does anyone know any solution? I will once again inform MG Poole and hope they will be able to offer a more permanent solution.
Thank you for the wealth of information already available on this forum.
