Technical Service
This Service Information bulletin supersedes SI 18 02 12 dated May 2012.
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.
BMW centers must ensure recalls are completed after having been notified by BMW of North America, LLC (BMWNA) that a safety-related defect
or noncompliance exists in any motor vehicle or item of replacement equipment in the center's possession at the time of notification. In BMW NA's
case, this notification would typically be made by the issuance of a recall notification in the form of a Service Information bulletin (SIB) or
transmission of a Dealer Communication System (DCS) recall message.
Under the National Traffic and Motor Vehicle Safety Act of 1966, as amended, if a recall campaign is announced by BMW NA, centers must ensure
that all recalls on new vehicles and new items of replacement equipment are completed BEFORE delivery to the consumer. This means that centers
may not legally deliver new motor vehicles or new items of replacement equipment to consumers with an open recall.
The Safety Act also prohibits centers from selling or leasing the motor vehicle or item of replacement equipment, unless and until the open recall has
been completed BEFORE delivery. This also pertains to vehicles in the Certified Pre-Owned program, and to items of replacement equipment.

Finally, BMW centers should not sell or use parts that have been recalled by BMW NA. Please follow the specific instructions provided by BMW
NA on the return or disposition of the parts.

SUBJECT
Voluntary Emissions Recall Campaign 11E-A03: Check and/or Replace Emissions Monitoring Components
MODEL
E70 and E90 with the M57Y engine produced from January 2008 to September 2009
SITUATION
1. The Selective Catalyst Reduction (SCR) catalyst has been improved to increase emissions stability over the service life of the vehicle.
2. The SCR mixer has also been improved to optimize the Diesel Exhaust Fluid (DEF) mixture when introduced into the exhaust system.
3. Under certain driving conditions, the High-Pressure (HP) EGR valve may become restricted with excessive soot. This restriction impedes the
emissions performance of the HP EGR valve. This situation may lead to the Service Engine Soon lamp illuminating. An optimized EGR valve
has been developed to limit this soot buildup.
Note:
These improved parts may have already been replaced during a previous service visit. It will be necessary to inspect these components first
before replacement.
4. Reprogramming of the DDE to optimize these improved emissions monitoring components.
AFFECTED VEHICLES
This Emissions Recall Campaign involves X5d and 335d models that were produced from January 2008 to September 2009.
In order to determine whether a specific vehicle has had this Emissions Recall Campaign completed or is affected by this Emissions Recall
Campaign, first check if the "Emissions Recall Campaign Completed" label SD 92-435 is attached to the right (passenger) rear side of the hood in
the engine compartment, close to the windshield. If the label is found, the campaign has already been performed. If the "Emissions Recall Campaign
Completed" label is not present, 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.

PARTS INFORMATION
LABEL INSTRUCTIONS
After the vehicle has been checked and corrected, obtain a label (SD 92-435) and with the indelible marker provided, legibly print the Recall name,
Recall number, and dealer code (5 digits) on the Recall Completion Label (see illustration). An initial quantity of 100 labels will be sent to all BMW
centers. Peel the label from its backing and affix it to the right (passenger) rear side of the hood in the engine compartment, close to the windshield.

For California centers only: it is required by the California code of regulations that an executed orange "Vehicle Emission Recall - Proof of
Correction" certificate (SD92-084, see illustration) be provided to each customer (for vehicles registered in the state of California), once the recall
on his or her vehicle has been completed.
Note: additional labels can be ordered online at BMW TIS.
WARRANTY INFORMATION
Correction
Inspecting the SCR catalyst:
Check the part number of the SCR catalyst (1). If the part number is not 18 30 8 509 753 (E70) or 18 30 8 509 750 (E90), the SCR catalyst will need
to be replaced. Follow Repair Instruction 18 00 020 "Remove and refit complete exhaust system" to replace the SCR catalyst.
Note:
If replacement is necessary, also perform the SCR mixer check/replacement at the same time.

Inspecting the mixer:
Remove the front pipe of the SCR catalyst to gain access to the mixer.
The original style mixer has a multiple fin arrangement (1). This mixer will need to be replaced with P/N 18 30 8 513 445 (E70) or P/N 18 30 8 512
438 (E90).
If the updated mixer has already been installed, it will have one set of fins (2). No replacement is necessary. Reinstall the SCR front pipe to the down
pipe of the DPF.
Inspecting the EGR valve:
Remove the charge air pipe at the throttle (ignition off). Using a flashlight, look through the throttle (1) and inspect the EGR valve.

The updated EGR valve (P/N 11 71 8 517 217 or P/N 11 71 8 512 526) has the valve and seat directly in the airstream of the throttle (1). If this
valve is installed, no further action is needed. Reinstall the charge air pipe.
The original EGR valve has a diffuser in the airstream flow from the throttle (2). The valve for EGR actuation is seated further into the EGR
airstream. Replace this valve with P/N 11 71 8 512 526 (Repair Instruction 11 71 501).
The DDE will also need to be programmed as part of the Recall. If the EGR valve is replaced, the DDE will need to be programmed after the new
EGR valve is installed. This new software package contains the necessary software to adapt to the new EGR valve strategy.
Program the vehicle using ISTA/P 2.46.3 or later.
Note that ISTA/P will automatically reprogram and code all programmable control modules that do not have the latest software.
For information on programming and coding with ISTA/P, refer to CenterNet / Aftersales Portal / Service / Workshop Technology / Vehicle
Programming.
