Hi all ,I have a 2003 sl350 ,I’ve been having an issue where I’m getting a warning on the dash electrical components offline ,renewed agm battery but only seems to keep the warning at bay for 6-7 weeks ,had battery tested all good holding 12.66 on a drop test and is receiving 14.2 volts from the car when it’s running ,there must be a draw on the battery from somewhere but I’m stumped ,if you have any ideas help please ,cheers
