SUBJECT
Service Action: Check and Replace TCU
MODEL
E46 (3 Series), E85 (Z4), E53 (X5), E83 (X3).
SITUATION
Low ambient temperatures (below 32锟斤拷F) may cause the TCU (Telematics Control Unit) to go into reset mode. The result is that calls to BMW Assist
or "SOS" calls will not be completed.
Once in reset mode, the TCU will remain in this condition even with the ignition turned off. This could result in a discharged battery.

To minimize customer's inconvenience caused by this service action, pick-up (and deliver after repair) the affected vehicle from customer's home or
provide appropriate alternative transportation.
Customers will be impressed when you return their cars cleaned inside and out and with a full tank of gas. Reimbursement information for the
vehicle fueling and valet costs may be found in the Warranty portion of this bulletin.
AFFECTED VEHICLES

CAUSE
Telematics Control Unit (TCU).
PROCEDURE
1. Read the ESN number from the label in the Owners Manual insert. The ESN is shown immediately above the bar code.
Note:
If the Owner's Manual insert cannot be located, connect the DISPlus/GT1 and perform a "Short test". Select "Control Unit Functions" /
"TCU Telematic Control Unit" / "only US" / "Read ESN number", and press "Display" to read the ESN number.
420
2. Using the TIS website, in the "Bulletins and Measures" section, press the special button marked "TCU lookup".
Follow the on-screen prompts to enter the vehicle VIN and ESN, then press "Enter" to display whether the TCU must be replaced, or not be
replaced. Press the "Print" button and attach the printout to the repair order.
3. For vehicles where the TCU does not have to be replaced, no further work is necessary.
For vehicles where the TCU must be replaced, switch off the ignition and remove the TCU, which is located behind the trim in the left luggage
compartment (on convertibles the TCU location is on the left rear bulkhead, accessed via the trunk).
4. Before installing the replacement TCU, make a note of the Electronic Serial Number (ESN) and copy this information onto the "TCU
Registration Form" attached to this Service Information, and fax the form to the number indicated on the form. This will register the new TCU
to this vehicle.
5. Remove the ESN label from the replacement TCU, and affix the new label over the existing label on the Owner's Manual insert (P/N 01 49 0
157 963).
6. Install the new TCU and code it with DIS CD36.1 or higher (E46, E53) or CIP 10.1 or higher (E83, E85).
7. 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.
8. Test the BMW Assist service for proper operation by placing a test call.
Note:
The MFL button on the steering wheel must not be used.

[NEW] 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

LABEL INSTRUCTIONS
422
This Service Action has been assigned code number 390. After the vehicle has been checked, and corrected if necessary, obtain a label (SD 92-245)
and:
a. emboss your BMW dealer warranty number in the middle of the label (1);
b. punch out code number 390(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.
