[NEW] designates changes to this revision
PERFORM THE PROCEDURE OUTLINED IN THIS SERVICE INFORMATION ON ALL AFFECTED VEHICLES THE NEXT TIME THEY ARE IN THE SHOP FOR MAINTENANCE OR REPAIRS.
SUBJECT
Voluntary Emissions Recall 06E-A03: S62, S54 - DME Reprogramming for OBD Communication
MODEL
Z3 M roadster/coupe with S54
E46 M3 coupe/convertible with S54 up to 8/27/04 production
E52 Z8 with S62
E39 M5 with S62
SITUATION
In certain conditions, when the ignition is switched off and on again, the OBD communication cannot be established between the MSS52, or MSS54 DMEs and the generic scan tools. As a result, MY '00-04 vehicles equipped with Motorsport S62 and S54 engines may not be able to pass a state emission inspection where the testing procedure consists of scanning OBD readiness codes.
OBD communication and on-board diagnostic is always possible when using BMW DIS or GT1 testers.
In order to remedy the situation, BMW is conducting a Voluntary Emissions Recall Campaign to reprogram engine control units (DME) on all affected vehicles.
AFFECTED VEHICLES
This Recall Campaign involves MY '01-'03 Z3 M roadster/coupe vehicles with S54 engines, MY '00 -'03 Z8 and M5 vehicles with S62 engines, and M3 coupe/convertible vehicles with S54 engines which were produced from series introduction up to 08/27/2004.
In order to determine if a specific vehicle is affected by this Recall Campaign, it will be necessary to utilize the "Service Menu" of the DCS (Dealer Communication System). Based on the response of the system, either proceed with the corrective action or take no further action.
The Chassis Number Ranges shown are only for informational purposes and are not to be considered as the only deciding factor.
[NEW] CORRECTION
On all affected vehicles, reprogram the DME using Progman 21.2 or higher.
Also, on M3 vehicles equipped with SMG transmission, reprogram the SMG control module using Progman 21.2 or higher.
[NEW] IMPORTANT:
DO NOT PERFORM THE TEACH-IN PROCEDURE AFTER REPROGRAMMING THE SMG.
It is NOT necessary to perform any of the SMG Teach-in Transmission procedures (e.g., "Teach-in clutch valve characteristic values", "Adapt compete transmission", or "Teach-in clutch slip point") after reprogramming the SMG control module. Readapting the complete transmission or clutch characteristic/biting point after SMG module programming may cause harsh shifting or incorrect clutch engagement.
PROCEDURE
1. Connect an approved battery charger and DK diagnostic head.
2. Start a new Progman session and select the appropriate vehicle series.
3. Select "Load Software", and then answer "NO" to the query as to whether any of the control modules have been replaced.
4. Select DME (SMG) from the list of the control modules.
5. Select "Program" menu, and then "Update Software" from the submenu. The measure plan will be determined and displayed.
6. Select "Accept" and "Start" to start programming. After programming is completed, if necessary, determine and clear any faults stored in control modules using DIS/GT1.
The part numbers for DME control module should be displayed in the final report after the reprogramming.
IMPORTANT:
The correct DME part numbers (regardless of the hardware level - MSS54 or MSS54HP) will be selected through the automatic programming path.
Manual determination of the basic and programmed control module numbers should be used only when the DME has already "crashed" during an aborted Progman session.
In such a case, to determine the correct hardware level (MSS54/MSS54HP), use the "New part no. progr. ctrl." printed from the failed Progman Measures Plan; or determine it from the DME label (see illustration) and part numbers provided in this Service Information.
The following part numbers for the SMG control module should be displayed in the final report after the
reprogramming of a M3:
LABEL INSTRUCTIONS
After the vehicle has been checked and corrected, obtain a label (SD 92-323) and with a ball-point pen print your dealer code (5 digits) on the Recall Completion Label (see illustration). An initial quantity of 100 labels will be sent to all BMW automotive 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 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 their vehicle has been completed.
Note:
Additional labels can be ordered on on-line at BMW TIS.
WARRANTY INFORMATION
Covered under the terms of the BMW New Vehicle Limited Warranty.
Reimbursement for this Recall Campaign will be via normal claim entry utilizing the information shown.
