Renewing the reductant fil-
ters
There is always 1 reductant pump with a filter in
the reductant tank (buffer tank). However, there
may be 1 additional reductant pump with a filter
between the main reductant tank and the buffer
tank.
1. Wipe clean around the filter housing to pre-
vent impurities from penetrating it.
2. Remove the filter housing. Use a 46 mm
socket.
There may be a lot of reductant in the filter hous-
ing and it may spill out. Wear protective gloves.
Always rinse away reductant spillage on connec-
tions and other parts with lukewarm water to pre-
vent corrosion. If reductant seeps into electrical
connections or electrical cables, these must be
renewed.
3. Remove the sealing diaphragm.
4. Remove the old reductant filter and fit a new
one.
