We would like to point out that when filling the AdBlue tank it is essential to ensure that only pure AdBlue is poured in.
During the course of inspection, it has come to our attention that pump modules frequently contain diesel, gasoline and/or mineral oil residue. The pump modules and AdBlue hose lines are not resistant to such fluids.
In order to prevent repeated failure of the pump module, the following components must be replaced on vehicles on which the AdBlue tank has been filled with the wrong fluid:
AdBlue tank
All AdBlue hose lines
Pump module
We advise against cleaning the components as residue from the cleaning agents could damage the pump module and the metering device.
Please note that repairs required as a result of filling the AdBlue tank with the wrong fluid are not included in the scope of warranty.
