Service bulletins for the 2014 BMW 535i

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

366 on file from NHTSA, as of 2026-10-19.

6518132018-12-03. Service bulletin. EQUIPMENT; ELECTRICAL SYSTEM. Touchpad Integrated in the iDrive Controller Is Intermittently Inoperative. Intermittently the Touchpad integrated in the iDrive controller is inoperative. * No entries can be made using the Touchpad * Fault code is stored in the touch-box control unit Software error in the touch-box control unit (TBX)
6307132018-12-03. Service bulletin. ELECTRICAL SYSTEM; EXTERIOR LIGHTING. Daytime Running Light Does Not Switch ON. The DRL (Daytime Running Light) is off and cannot be switched on after importing the personal profile from another vehicle. The CID (Central Information Display) display shows that it is active. CAUSE Software error when importing the personal profile from a vehicle which has a different head unit
6122132018-12-03. Service bulletin. POWER TRAIN; ELECTRICAL SYSTEM:12V/24V/48V BATTERY. """Increased battery discharge!"" CC Message upon Startup. CAUSE A software error in the Intelligent Battery Sensor causes an incorrect State of Charge (SoC) to be stored in the DME. The power management system then interprets this as a heavily discharged battery and informs the customer via a CC message. In reality, the battery does not have a problem."
8404132018-12-03. Service bulletin. ELECTRICAL SYSTEM; EQUIPMENT:ELECTRICAL. "TCB: Emergency Call Is Disabled. A Check Control message shows ""Emergency call failure."" When the SOS button is pressed, the call is not made by the TCB (Telematics Communication Box). Fault code 0XB7F33F is stored in the TCB. CAUSE TCB application error"
6102112018-12-03. Service bulletin. ELECTRICAL SYSTEM. Advanced Onboard Battery Diagnostics. INFORMATION Starting with the introduction of the F10 (5 Series), an advanced intelligent battery sensor has been used. This now makes it possible for the vehicle to monitor the condition of the battery in order to determine if the battery needs to be recharged or replaced, along with the remaining capacity of the battery. The analysis and testing of the battery's SoC (State of Charge) and SoH (State of Health) is now performed using ISTA (Integrated Service Technical Application) diagnosis. A separate test using a battery tester is no longer needed.
6206132018-12-03. Service bulletin. ELECTRICAL SYSTEM; ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL. Condition Based Service Due Date Is Reset to 01/2000. The Condition Based Service (CBS) due date is reset to 01/2000 and cannot be updated for: * Oil Service * Check Vehicle Note: No fault code is stored Software error in the Instrument Cluster

B8402142018-12-03. Service bulletin. ELECTRICAL SYSTEM. ?CONNECTEDDRIVE/BMW ASSIST SYSTEM DIAGNOSIS INFORMATION. ConnectedDrive/BMW Assist features are partially or completely inoperative. This Service Information bulletin is being published because vehicles are down for an extended period of time when researching system failures with ConnectedDrive or BMW Assist. This Service Information bulletin will assist you both in identifying the issue and providing technical support. CAUSE Not enough information is available for BMW NA engineers to assist the technician in diagnosing the root cause.
8405132018-11-26. Service bulletin. ELECTRICAL SYSTEM. TCB: Emergency Call Is Erroneously Triggered. An emergency call is erroneously made with no input from the driver. The following fault codes are stored in the TCB: * 0xB7F325 - Emergency call loud speaker: break in circuit * 0xB7F319 - Emergency call button: short circuit * 0xB7F326 - Emergency call loud speaker: short circuit to earth * 0xB7F33E - Automatic emergency call triggered frequently CAUSE TCB control unit error

One or more of the following scenarios may occur: * Unable to activate the parking assistant via the iDrive * When activated, the vehicle does not locate a parking spot * Does not assist with parking the vehicle CAUSE Software error in ISTA/P 2.49.0 programming data
6405132018-11-26. Service bulletin. ELECTRICAL SYSTEM. HV Battery Expansion Valve Sticking. The high-voltage battery is cooled by refrigerant as part of the vehicle's AC system. It is regulated using an expansion valve at the base of the battery itself. This expansion valve can become stuck in the open position, either intermittently or permanently. Fault code 21F107 - Cooling valve: valve couldn't be closed will be stored in the SME. CAUSE 1. Excess material from the manufacturing process can become lodged in the valve, causing it to stick open. 2. The diagnostic software in the SME control unit is not robust enough and can lead to a fault being set when a particular threshold is reached, despite the fact that the valve is not actually sticking.
6138122018-11-26. Service bulletin. ELECTRICAL SYSTEM. "Service Action: Program Control Units (CAS). After programming/coding the vehicle with ISTA/P 2.48.1 or earlier, the Car Access System (CAS) was incorrectly coded. This causes the anti-theft alarm system panic button on the remote control to not function. In order to determine whether a specific vehicle has had this Service Action completed or is affected by this Service Action, first check the B-pillar label for code number 637. If code number 637 has been punched out, the campaign has already been performed. If code number 637 has not been punched out, it will be necessary to utilize the ""Service Menu"" of DCSnet (Dealer Communication System) or the Key Reader. Based on the response of the system, either proceed with the corrective action or take no further action. Important Note: A campaign can be reserved in ISPA Light as ""Pending"" prior to submission of a claim. If you find this campaign reserved, please verify the reason before attempting to perform this repair."
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.
6513132018-11-26. Service bulletin. EQUIPMENT:ELECTRICAL; ELECTRICAL SYSTEM. "Headunit-High: CID Is Blank and ""NO SIGNAL"" Is Displayed. Intermittently the Central Information Display (CID) is blank and ""NO SIGNAL"" is displayed on the CID. ??Fault Code B7F8C3 ""no response from CID (HW error: loss of CID communication)"" is stored in the HU-H Hardware error in the Headunit-High"
6506132018-11-26. Service bulletin. ELECTRICAL SYSTEM. CHAMP2: Integrated Cooling Fan Is Noisy Intermittently. Intermittently, the cooling fan integrated in the CHAMP2 head unit (Radio Professional) is noisy. * More noticeable after the ignition is turned off * The cooling fan runs for approx. 6 minutes (until CHAMP2 enters sleep mode), depending on the ambient temperature Settings of the fan characteristics: the fan keeps running after the ignition is turned off
6506132018-11-26. Service bulletin. ELECTRICAL SYSTEM. CHAMP2: Integrated Cooling Fan Is Noisy Intermittently. INFORMATION Do not replace parts and do not perform a repair attempt! Explain to the customer that this only happens at high ambient temperatures, which keep the fan running after the ignition is turned off. The fan stops running when the head unit enters sleep mode (after approx. 6 minutes). This Service Information will be updated as soon as a solution is available. A software solution is expected to be available with ISTA/P 2.49.0 in March 2013.
