Bulletins, newest first
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.
1701132018-12-03. Service bulletin. ELECTRICAL SYSTEM; ENGINE AND ENGINE COOLING. Service Action: Replace Coolant Expansion Tank. The low coolant level warning may come on in the information display. CAUSE Insufficient contact at the electrical connector for the coolant level sensor causes an inaccurate reading of the coolant level.

The Service Engine Soon lamp is illuminated; Engine Malfunction warning is illuminated; and the vehicle has reduced power output. Various faults related to VANOS operation are stored in the DME. While performing the test plan, the results may appear to be inconclusive because the fault will not clear from DME Fault Memory. The ISTA/D diagnostic test plan does incorporate a VANOS bleed function, but it does not advise the technician to bleed the VANOS system after a VANOS or engine oil supply component replacement. CAUSE This is due to an error in the current level of ISTA/D. The error will be corrected with ISTA/D 2.41.0.
B5110162018-12-03. Service bulletin. EQUIPMENT; STRUCTURE:BODY:DOOR. ?GROANING NOISE FROM DOORS. A groaning noise is heard from any of the doors when driving over rough road surfaces.

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.

B1609182018-11-26. Service bulletin. ENGINE AND ENGINE COOLING:ENGINE:DIESEL. SCR SYSTEM FAULT 805256 STORED IN VERY COLD WEATHER. After the vehicle is exposed to prolonged temperatures under -9°C (15.8°F) and is then driven a long distance when temperatures are above -9°C (15.8°F), the check engine light may be illuminated. The following fault may be stored in the Digital Diesel Electronics (DDE) 805256 - Active tank filling level sensor, signal: echo fault In low temperature under -9°C (15.8°F) a layer of ice may form in the active tank. This can result in an incorrect level measurement after the vehicle is driven.
6504132018-11-26. Service bulletin. EQUIPMENT. Service Action: Real Time Traffic Information Activation. The Real Time Traffic Information (RTTI) is inoperative. ??The traffic information icon is missing from the menu in the navigation map screen.

5202132018-11-26. Service bulletin. SEATS. Front Seat Headrest Height Changes. The left or right front seat headrest can no longer be lowered to its lowest position, and is at a different height than before.
5201132018-11-26. Service bulletin. SEATS. "Front Crash-Active Headrest Has Limited Height Adjustment. INFORMATION This bulletin will help you understand the features of the crash-active headrest and explain the benefits to your customers and center staff. 1. Learn the safety features and operation of the front seat and crash-active headrest. Photos A and B: In the event of an accident, the rear passenger must be able to move the front seatback forward, regardless of the seat position. This allows the rear passenger an easy exit from the rear seat of the vehicle, even if the electrical power source is no longer available. 2. When the seatback is manually moved, the headrest must have free movement throughout the full range of the seatback. Photos C and D: The headrest and seatback must be able to move fore and aft without contacting the roof or sun visor, regardless of seat position. The headrest height will automatically adjust to maintain this clearance, regardless of seat position. 3. In case of an accident, the crash-active headrest will be automatically activated forward to reduce the distance between the occupant's head and the headrest. This results in increased safety for the occupant. Photo E shows the headrest in the normal position. Photo F shows the headrest in the ""active"" position and will not contact the roof. Note: The headrest's chrome bar supports can be seen. "
