Maintenance and Service
Diesel engine
Exchange of AdBlue® filter insert:
– Exchange the AdBlue® filter insert every second engine oil change.
– Place a suitable receptacle under the AdBlue® pump and screw out the filter hous-
ing (4). Remove the frost protection membrane (6) and the filter insert (5) from the
AdBlue® pump module.
– The filter insert should be disposed of according to the local regulations.
– Use a new AdBlue® filter insert (ROPA item no. 303019500).
ATTENTION
Use only the supplied lubricant spray from Mercedes-Benz for greasing. Make sure
this lubricant is used extremely sparingly, otherwise it may cause damage to the
AdBlue® system.
– Put the new filter insert (5) in the AdBlue® pump module.
– Put the frost protection membrane (6) over the filter insert.
– Spray thinly the sealing bead on the frost protection membrane and the thread of
the AdBlue® pump module using the provided lubricant.
– Screw the filter housing (4) again on and tighten it with a torque of 80 Nm.
– The AdBlue® system bleeds itself automatically, manual bleeding is therefore not
necessary.
