this is a very common issue with burned melted wiring at the exhaust flex pipe on the passenger side of the engine.

you will find that most likely the flex pipe rusted or broke and leaked hot gases that melts the wiring and shorts the wiring,

i think I have pictures i will check.

here are some pictures, what happens is the wiring to the front nox sensor gets shorted and blows the fuse.

is there any other place that could cause problem
Mercedes Mechanic: Lou P. master tech, Mercedes Technician replied 22 days ago

yes, that fuse is shared between multiple items for the sensors and the engine module and the adblue module.

but the most common is the front nox sensor, i would unplug the sensor and see if the fuse still blows.

have you checked this wiring yet?
