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. |
