An auxiliary battery problem on the Mercedes Sprinter

Model: Mercedes Sprinter MK 3, Br910, Br907 - Years 2018-2026
Part: Battery

In this video, we will see what to do if our Mercedes Sprinter indicates a malfunction of the auxiliary battery. This battery is located under the driver's seat, and we access it from the rear seat, as it is contained inside a box covered by a rubber lid. It is not easy to identify the right component inside, as the tangle of wires does not help to move in the right direction, but we must take the red and brown wires and remove this small box, which is indeed the auxiliary battery. We can find it on AliExpress with the code 1005005235571918 at the price of 55.37 euros, with free delivery. We reconnect the pins and put it back in place. We put the rubber cover back in place and turn on the ignition; the warning light has disappeared.
