Technical Service
PERFORM THE PROCEDURE OUTLINED IN THIS SERVICE INFORMATION ON ALL AFFECTED VEHICLES BEFORE CUSTOMER
DELIVERY OR THE NEXT TIME THEY ARE IN THE SHOP FOR MAINTENANCE OR REPAIRS.
SUBJECT
Service Action: Replace the Selective Catalyst Reduction (SCR) Metering Unit
MODEL
E90 with the M57Y engine
SITUATION
Metering units installed on certain E90 vehicles with the M57Y diesel engine will clog due to crystallization of the DEF fluid. An improved metering
unit has been introduced.
AFFECTED VEHICLES
This Service Action involves E90 vehicles with the M57Y diesel engine which were produced from June 2009 to September 2010.
In order to determine whether a specific vehicle has had this Service Action completed or is affected by this Service Action, first check the B-pillar
label for code number 616. If code number 616 has been punched out, the campaign has already been performed. If code number 616 has not been
punched out, it will be necessary to utilize the "Service Menu" of DCSnet (Dealer Communication System) or the Key Reader. Based on the
response of the system, either proceed with the corrective action or take no further action.
PROCEDURE
Replace the metering unit as described in Repair Instruction RA 18 31 130.

C. Affix the label to the B-pillar as shown.
If the vehicle already has a label from a previous Service Action/Recall Campaign, affix the new label next to the old one. Do not affix one label on
top of another one because a number from an underlying label could appear in the punched-out hole of the new label.
