AFFECTED VEHICLES
This Service Action involves E46 (3 Series) vehicles, which were produced from 9/2003 to 10/2003.
In order to determine if a specific vehicle is affected by this Service Action, 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.
VIN specific parts have already been sent to the wholesale or retail BMW center of record as of October 2003. We anticipate most repairs will be performed by that BMW center. Please note the "Parts Information" provided in this Service Information.
The Chassis Number Ranges shown are only for informational purposes and are not to be considered as the only deciding factor.
CAUSE
1. Telematics Control Unit (TCU) missing.
PROCEDURE
1. Access the TCU location in the left luggage compartment by removing the trim. On convertibles, the TCU location is on the left rear bulkhead, accessed via the trunk
[NEW]2. Before installing the new TCU, remove from it one copy of the Electronic Serial Number (ESN) label and place a copy on the repair order for reference during warranty claim entry. You will be asked for the new TCU "ESN" when submitting a claim in DCS net.
[NEW]3. If a second ESN label is available on the new TCU affix it over the existing label on the Owner's Manual insert (P/N 01 49 0 157 963).
4. Install the new TCU and code it with DIS CD36.1 or higher.
5. Reinstall any removed vehicle trim.
6. NOTE:
In order that the TCU replacement is properly recorded, FASTA must be activated in the DISPlus/GT1. For details on activating FASTA, refer to SI B07 07 01. Using DISPlus/GT1, select "Diagnosis" and delete any stored fault codes.
7. Test the BMW Assist service for proper operation by placing a test call using the SOS button.

The MEL button on the steering wheel must not be used.
PARTS INFORMATION
Please order by placing the VIN in the comment/text field of your order. The VIN will be checked against the VIN ranges provided.
You may order this part either on a VOR or a stock order. Only orders for single units accompanied by a valid VIN will be processed. Multiple quantity and non-VIN specific orders will be cancelled.
If you need a TCU to replace a unit in a vehicle that is outside the VIN ranges provided, place the order in the same manner and contact the PCG @ 1-800-272-0202 ASAP. This will prevent your order from being cancelled due to using a VIN that does not appear on the master list.
LABEL INSTRUCTIONS
This Service Action has been assigned code number 378. After the vehicle has been checked, and corrected if necessary, obtain a label (SD 92-215) and:
a. emboss your BMW dealer warranty number in the middle of the label (1);
b. punch out code number 378 (2) printed on the label and,
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.
WARRANTY INFORMATION
[NEW] Reimbursement for this Service Action will be via normal claim entry utilizing the following information.
