Purity
Assuring the purity of DEF is particularly important with respect to avoiding malfunctions in the exhaust gas aftertreatment system.
If DEF is pumped out of the DEF tank, e.g.
during repair work, it must not be returned to the tank. The purity of the fluid can no longer be guaranteed.
Impurities in DEF (e.g. due to other
service products, cleaning agents or dust)
lead to:
- increased emission values
- damage to the catalytic converter
- engine damage
- malfunctions in the BlueTEC exhaust gas aftertreatment system
