B5409072018-12-10. Service bulletin. STRUCTURE:BODY; ELECTRICAL SYSTEM; EQUIPMENT. ?RETRACTABLE HARDTOP STATUS REQUEST SUPPLEMENT. INFORMATION Documents have been developed showing the known correct statuses for all hall sensors and micro switches used to operate the retractable hard top (RHT). This document is intended to act as a supplement to the diagnostic information available in ISTA. Comparing these statuses to the actual statuses of a vehicle with a functional problem may assist in narrowing down which sensor/switch is contributing to the functional problem. For E93, the status request may be found by connecting the car to ISTA and selecting: Control module functions/CTM Convertible top module/Diagnosis Requests ?Sensors/Switches For F33/F83, the statuses should be checked using the applicable test plan as instructed in attachment B54 09 07 F33 F83 RHT Status.pdf. For I15, the statuses should be checked using the applicable test plan as instructed in attachment B54 09 07 I15 Top Status.pd

CAUSE Not enough information is available for BMW NA engineers to assist the technician in diagnosing the root cause.
B6130172018-11-26. Service bulletin. ELECTRICAL SYSTEM. RAIN/LIGHT SENSOR (RLS): OIL LEAKAGE FROM GEL PAD. ??Oil leaking from the Rain/Light Sensor (RLS). Note: This oil serves as a separation medium between the RLS mounting gel pad and the windscreen. The oil ensures damage free disassembly in case of repair. CAUSE The oil that serves as the separation medium of the Rain/Light Sensor (RLS) gel pad and the windscreen leaks out. Expose the Rain/Light Sensor (RLS) and properly clean the area of all oily residue. Note: The separating oil usually leaks only once from the pad at the RLS. Due to the small oil quantity in the gel pad, additional oil leakage is not plausible. Leaking oil does not impair the function of the RLS.

1305142018-11-26. Service bulletin. ENGINE. . INFORMATION To properly diagnose the customer's complaint, the applicable test plan for the misfire faults stored in the DME must be performed to avoid repeat repairs. If a misfire fault is not stored in the DME memory and an engine related drivability complaint is received, follow the path below to manually start the misfire test plan (AT1214_TVD4_MISFIRE_20): 1. Perform a vehicle test. 2. Select "Function Structure." 3. Select "01 Engine." 4. Select "Engine electronics MEVD." 5. Select "Misfire detection." 6. Follow the steps in the test plan and select "Basic check (start)" first. Do not select "Additional check" at this time. 7. If the result of the "Basic check" indentifies a fuel system component failure, replace the identified component. If the result of the "Basic check" test plan was inconclusive, go to step 7. After the component replacement, perform the "Basic check" portion of the test plan again to verify if the diagnosis was correct and the vehicle condition has been rectified.
1229142018-11-26. Service bulletin. ENGINE AND ENGINE COOLING. Reduced Engine Performance. When driving with high outside ambient temperatures, repeated stop and go, or high-load operation over longer distances, the engine performance can be reduced.

One or both of the following faults are stored in the DME: 1A2108: Electric fan, self-diagnosis, interval stage 1: Minor fan fault 241400: Electric fan, diagnosis feedback 1: Fan slightly stiff The Service Engine Soon lamp (MIL) would not be illuminated in these situations. 1. A DME software error in the control of the 600W electric fan over-boost or high speed function 2. The electric cooling fan design was not robust enough for continuous over-boost or high-speed operation.
B6124172018-11-26. Service bulletin. STEERING: STEERING WHEEL/HANDLE BAR; ELECTRICAL SYSTEM. "?STEERING WHEEL BUTTONS DO NOT FUNCTION RELIABLY. ? Sporadic or continuous malfunction of multifunction steering wheel buttons ? CC Message ""Cruise control without function"" displayed ?

6609142018-11-13. Service bulletin. ELECTRICAL SYSTEM; LATCHES/LOCKS/LINKAGES:TRUNK LID:LOCK. Unlocking Trunk with Remote Unlocks All Doors. After programming the vehicle with ISTA/P 2.47.1, unlocking the trunk with the remote changes to unlocking all the doors. An application error occurred after programming the vehicle to the Personal Profile Setting (PIA) in the Front Electronic Module (FEM).
6103142018-11-13. Service bulletin. ELECTRICAL SYSTEM. Check Control Messages Related to Battery Charge During Cold Ambient Temperatures. On cold days with an outside ambient temperature of less than 15F, customers may notice a check control message related to the battery that is displayed on the instrument cluster and the control information display. Under these conditions, the vehicle starts. Various power management faults can be stored: z 213901 - Power management: Reduction or shutdown of individual electrical consumer z 8040BD - Reset or deactivation of Terminal 30F z 8040B9 - De-activation of terminal 30B: Top start capability limit reached z 8020E8 - Reset or deactivation of terminal 30F z 800E89 - FRM: start capability limit reached with lights active during stationary mode z 93076B - Deactivation of terminal 30B: upper start capability limit reached z 93076A - Deactivation of terminal 15: upper start capability limit reached, but deactivation preventer active z 93076C - Deactivation of terminal 30B: upper start capability limit reached, but deactivation preventer or legal loads active z 930769 - Deactivation of terminal 15: upper start capability limit reached Note: When the outside temperatures drop below 46F, the charging system is switch to full charge. CAUSE z The check control message (ID 229) is caused by a heavily discharged battery. z The check control message is triggered when the current state of charge (SoC) of the battery approaches the minimum SoC that is required to start the vehicle (start capability limit). z In low outside ambient temperatures, the start capability limit of the vehicle is higher. Therefore it takes more energy from the battery to start a cold engine. z Without the early warning of the check control message, the current state of charge would drop below the start capability limit and the vehicle would not start. z The vehicle's intelligent power management system actively takes measures to increase the charge of the battery, such as increasing idle speed and reducing or shutting
5131142018-11-13. Service bulletin. EXTERIOR LIGHTING:HEADLIGHTS. Headlight Cleaning System: Functional Operation Change. The customer complains that the headlight cleaning system is not working properly and only works after several actuating attempts. CAUSE The "functional" operation of the headlight cleaning system was changed with integration level F020-14-07-500. The functional changes to the headlight cleaning system's operation will occur only after programming the vehicle with ISTA/P 2.53.0 or higher. INFORMATION The headlight cleaning system is no longer activated with the first stalk activation when the lights are on. The functional programming change now requires the stalk to be activated four times before headlight cleaning is activated. The change prevents automatic activation of headlight cleaning when the customer only wants to clean his/her windshield. This is normal operation and no parts should be changed.
