Diesel engine

Exchanging AdBlue® filter insert:
– Shut down the diesel engine.
– Wait for the AdBlue® pump (3) to stop,
because it generally automatically
drains the AdBlue/DEF hoses. Switch
off the main battery switch and wait
another 6 minutes.
– Place a suitable receptacle under the
AdBlue® pump and screw out the filter
housing (4).
– Pull the frost protection membrane (6)
from the filter insert (5).
– Press the puller (7) included in the fil-
ter insert with the wide side (labelled
Grey) into the filter opening until it
clicks.
– Pull 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. 304004100).
– Put the new filter insert (5) in the
AdBlue ® pump module.
– Put the frost protection membrane (6)
in the filter insert.
– Screw the filter housing (4) on and
tighten it with a torque of 20 (+5) Nm.
– The AdBlue® system bleeds itself
automatically, manual bleeding is
therefore not necessary.
– Start diesel engine . Check function
and check for leaks. Delete fault codes
in the error memory.
