Sprinter Battery drain

[ChristophK]

Good evening,
My 2013 sprinter is suffering from
some form of battery drain. After having it not driven for 2 weeks it would not start and I initially thought the kids played with the stereo or I left a light on. Battery charged and outside of the van keeps it charge.
I check today I found a battery drain of initially 1.4 amp and that drops to about 0.75 after 10 seconds. I initially thought of the reversing camera I had installed so checked and disconnected but nothing changed. Nothing else is on, no radio lights etc.

When I initially connect the battery I hear a sound from the dashboard and the instrument cluster needles move briefly which I think is normal.

Has anyone got any idea what might drain the battery at around 0.75 as it will be flat if I don't drive it for a while?


Many thanks for any suggestions

Christoph

Hi,



You’ll find fuses is the passenger footwell and under the drivers seat.

Whilst observing the current draw, start removing and re-inserting the fuses one by one until the current draw disappears.

Identify what that fuse is for in your owner’s manual or report back here for information. That component will be the cause of the draw.
