Hi, I’m not sure if I have a similar problem to that posted by Greek David but my 2011 Meriva battery is discharging. It has had a brand new battery and been in my local garage who coukd not fix the fault. They did put it on the machine and found the following issues:- B1325-03 control module power circuit, and B1520-91Wake up Short to ????? They suggested I go to a main dealer as they were unable to fix. Has anyone an idea of what this could be please, thought I would ask here first! Thanks all
