SUBJECT
[NEW] 2002 MY Various Electrical Complaints Caused by Software Errors
MODEL
E65, E66 (7 Series) up to 9/2002 Production
SITUATION
Customers may complain of the following:
1. Check Control shows service interval too short.
2. RDC fails intermittently, check control message and tires indicated in MMI are yellow.
3. Control Display and Instrument Cluster settings revert to Metric.
4. Poor FM radio reception.
5. Battery discharged because of increased closed-circuit current caused by door modules.
6. Airbag warning light is illuminated (SIM processor reset FC 93A8).
7. Comfort front seat headrests adjust to a predefined position every time the seat is moved.
8. Rear headrests move up and down on their own (Note: After programming with CIP 4.2 or higher, the rear headrests can be locked using the lockout switch on the driver's door).
9. Rear roller sunblind does not operate at low temperatures.
10. All doors unlock automatically as soon as engine is switched off and the remote is removed from the CAS (only when Drive-away locking is deactivated in VKM (Vehicle Key Memory).
11. The trunk lock button is locked on the 3rd press of the remote unlock button.
12. Total mileage shows 999,999 when ignition is switched on.
13. The Control Display check control symbol (vehicle symbol) is displayed incorrectly (wrong color).
14. The steering column position is not stored to a previously set value when key is changed.
15. Airbag light on, fault stored in SIM "93D9 Overvoltage shutdown".
16. The passenger side mirror doesn't return to its original position after automatic parking function.
17. No voice instructions are given from the navigation system when route guidance is activated.
18. Poor brightness and low contrast in Control Display.
19. A rapid double-click on the iDrive controller while in the "Tone selection" menu resets the sound settings.
20. When the engine is switched on, "Initialize Tire Pressure Control" is displayed.
21. Vehicle settings (for example: the settings for the freely allocated MFL button, Park Distance Control (PDC) screen settings, and the language in navigation menu settings) automatically change on their own.
22. When a vehicle is parked for extended periods exposed to high ambient temperatures, the Control Display may have a delay in startup (screen remains dark).
23. After the DMB was programmed using CIP 7.0 or 7.1 the customer may have driveability complaints, check engine light is on, "Engine malfunction due to driving style" appears in Control Display, multiple faults are stored in DME: misfire detection, manifold pressure sensor, air mass meter, Valvetronic power limitation, etc.
The following software errors were corrected with the release of CIP 8.2 (Target Data Status 6.75A)
1. The airbag warning light is on. The following fault codes are stored in fault memory, STVR 96E2, and STVL 9662 "communication pressure sensor" sets at low ambient temperatures.
2. If a destination was stored in the SVS address book and is recalled, a new destination, which was not previously stored, is adopted and the system initiates route guidance for that destination.
3. The airbag warning light is on. SZL FC 94EA "Steering Wheel Module communication" is stored. If the fault returns after updating the vehicle software using CIP8.2 or higher, replace the "Steering Wheel Electronics" control module.
4. After a brief interruption of the audio system (MOST bus reset), the volume adjustment switches to a louder/quieter setting.
5. Radio stations stored in the Control Display are deleted, moved or replaced by an unknown frequency.
6. The sounds system emits a pop/crackling noise when the vehicle is started at low ambient temperatures. Only vehicles equipped with Logic7 Amplifier.
7. When the auto headlight mode is active, the headlights do not turn off when vehicle is driven from dark ambient light conditions to brighter ambient light conditions (Only affects vehicles updated with CIP 7.22).
[NEW] The following software errors were corrected with the release of CIP 9.2 (Target Data Status 6.76)
1. Hesitation on acceleration from a stop.
2. After placing a telephone call (CPT8000) and leaving the iDrive in the communication menu, the iDrive is ineffective when returning to the vehicle.
3. Emergency transmission program when engine is started, EGS FC 4FB2 internal fault 3 (watchdog).
4. When the engine is switched off the warning "The transmission automatically shifts to P when the engine is switched off. Please consult your BMW center as soon as possible" is displayed. EGS FC 51 AC (CAN ID sensor inserted) is stored.
