Mercedes-Benz Sprinter (2006 – 2018) Fuse Box Location & Diagrams
This tutorial covers the locations and diagrams of the Mercedes-Benz Sprinter fuse boxes from 2006 to 2018. This article will show you how to locate and identify automobile fuses during troubleshooting or repair.
Electrical fuses
WARNING
If you manipulate or bridge a faulty fuse or if you replace it with a fuse with a higher amperage, the electric cables could be overloaded. This could result in a fire. There is a risk of an accident and injury.
Always replace faulty fuses with the specified new fuses having the correct amperage. Only use fuses that have been approved for Sprinter vehicles and that have the required fuse rating for the systems concerned. Components or systems could otherwise be damaged. The fuses in your vehicle switch off defective power circuits. If a fuse blows, all the components on the circuit and their functions will cease to operate. Blown fuses must be replaced with fuses of the same rating, which you can recognize by the color and fuse rating. Observe the infor mation about fuse rating in the fuse allocation chart. If a new fuse blows again, have the cause determined and rectified at a qualified specialist workshop. The fuse allocation chart and other information on the fuses can be found in the “Fuse allocation chart” supplement.
