Concerns: DME control unit
Information: This is to inform you of a voluntary Workshop Campaign on the above-mentioned vehicles. On the affected vehicles with Selective Catalytic Reduction (SCR), there is a possibility that the
fault memory entry P20FE00 "Reducing agentmetering unit malfunction" will be entered in
the DME control unit faultmemory and the Check Engine light will be activated because the
diagnostic setup of the SCR system is too sensitive in the low-temperature range, although the
AdBlue®metering quantity is still set correctly in this temperature range.
