Little update about this mind fkin situation.


Had no time yet to check the fuses, just tried to unplug stuff and leave the voltmeter inside during the day.


So i unplugged the webasto (the 2 plugs on it) because i forgot to try it, and the voltage stopped dropping. Then plugged it back to confirm, there was no more drain...


Also now after driving, the battery is staying around 13v at sleep (drops to 12.7 12.8 when unlocking, then back to 13). Left it overnight, unlocked locked few times meanwhile, now i get 12.97v.

Is it normal to have such voltage or it's not supposed to reach 13v on a 12v battery? Engine on i get around 14.1v.
