The Mercedes-Benz Sprinter is a large and luxurious vehicle, but it's common to have concerns due to its reported electrical issues. The electrical system in the Sprinter is not known for its reliability. You may encounter problems with the headlight assembly, instrument cluster, head unit/navigation system, or brake sensor monitors. When replacing any of these components, it's crucial to disconnect the negative terminal from the battery to prevent personal injury and avoid damaging the new part. Neglecting to do so could result in wasted money and potentially harm the new component.
I've experienced the left light going out twice in my new 2020 Sprinter van. Each time, I was able to fix it by removing fuse 69 and then putting it back in to reset the assembly. I haven't seen anyone else talking about this issue online. Just make sure to turn off all electronics in the van before trying this fix.
If your Mercedes Sprinter is experiencing electrical problems, it could be due to various factors. Faulty wiring may disrupt the proper flow of power, a malfunctioning battery or alternator can result in a lack of power, and a blown fuse is also a possibility. These issues can result in certain components not working correctly or failing to function as intended.
