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.
1204122018-12-03. Service bulletin. ENGINE. N55: Idle Fluctuates Briefly After a Cold Engine Start. Under certain engine cold starts, the engine idle may fluctuate during the first 10-20 seconds of operation before becoming stable. No faults will be stored in this situation, which will usually only occur at specific engine temperatures, making it difficult to reproduce in the workshop. Unfavorable DME software calibration
B1111172018-12-03. Service bulletin. ENGINE. ?ENGINE LEAK DIAGNOSIS ON TURBOCHARGED V8 ENGINES. When diagnosing an engine oil leak or a coolant leak on turbocharged V8 engines it is necessary to use a borescope to identify if the source of the leak is from under the turbochargers. Engine oil or coolant leaking from the bell housing area or the front timing chain cover area may be caused by the turbocharger itself, a turbocharger oil/coolant feed line or turbocharger oil/coolant return line. Do not remove the transmission and do not dissemble the engine before performing this inspection. If necessary, use engine oil leakage detection dye.
B1108152018-12-03. Service bulletin. ENGINE. N63 and S63 Engine: Valve Seal Replacement. Refer to the following applicable SIBs before replacing the valve seals. * B11 07 11 - Turbocharger Failure: Oil Supply and Return Line Blockage and Proper Repair * B11 07 12 - N63 Engine: Oil Consumption and/or Rough Running Complaints * B11 01 13 - N63 Engine: Engine Oil Consumption, Engine Oil Top-ups and Refill Capacity * B11 03 13 - Engine Oil Consumption (all models) If the valve seals are leaking, one of the following will help determine if the seals should be replaced. * Smoke from the tailpipe when starting or aggressively accelerating and decelerating the engine in addition to excessive engine oil consumption * Spark plugs fouled with engine oil and excessive engine oil consumption * Excessive engine oil consumption All Vehicles: On vehicles, where an excessive oil consumption between services is the only complaint, a complete oil consumption test as described in SI B11 03 13, must be performed first before replacing the valve seals. On vehicles exhibiting reproducible smoking from the tailpipe when hot, additional engine diagnostic steps (e.g. engine compression test, leak-down tests; inspection of the crankcase ventilation lines and turbo intake/outlet tubes for excessive oil accumulation) should be performed and documented prior to replacement of the valve seals, in order to eliminate other possible causes. Refer to the SIBs listed above for important diagnostic tips. Do not remove the intake manifolds to clean the intake valve carbon.
5203132018-11-26. Service bulletin. SEATS. Rattle Noise from Rear Seat Backrest. A rattle noise can be heard from the rear seat area when the vehicle is driven. CAUSE The left and right rear seat backrest locks have insufficient lubrication.

This situation may be more noticeable when driving in a bend in the road or on roads with a rising gradient. Unfavorable EGS and DME software calibration
1307122018-11-26. Service bulletin. ENGINE; FUEL SYSTEM, GASOLINE. N63 and S63 Engine: High-pressure Fuel Injector Replacement Procedures. The customer complains that one of the following scenarios has been encountered while operating the vehicle: * During a cold start in the morning, the engine runs very roughly and the Service Engine Soon lamp is illuminated. * During a hot start, the engine runs very roughly and the Service Engine Soon lamp is illuminated. ??While driving or idling, the engine will misfire and the Service Engine Soon lamp is illuminated. * Various misfire faults are stored in DME fault memory. CAUSE An internal failure of the high-pressure fuel injector can lead to incorrect operation.
1304092018-11-26. Service bulletin. ENGINE; FUEL SYSTEM, GASOLINE. "N54 Engine: Diagnosis of Cold Start Rough Running with Misfire Faults. The customer may complain that during the cold start in the morning, the engine runs very roughly and the Service Engine Soon lamp is illuminated. Various misfire fault codes (e.g., 29CC, 29D2, 29D1, 29D0, 29C0, 29CF) may be stored in the DME control module. The engine rough running complaint can be reproduced on a cold start in the workshop. During the course of diagnosis, the spark plugs, removed from the misfiring cylinders after the problem was reproduced, are found to be soaked (""wet"") with fuel, while the injector tips are covered with a layer of carbon deposit. Possible cause: high-pressure injector failure (leakage or incorrect spraying pattern) due to internal wear or unfavorable stock of tolerances IMPORTANT: For comprehensive N54 drivability diagnostics, always refer to the ""N54 Engine Diagnostic Fault Tree"" file (the current version ""02_14_13"" is found as a PDF attachment to SI B12 55 06)."
1208132018-11-26. Service bulletin. ELECTRICAL SYSTEM; ENGINE. "Service Action: Program Control Units (Auto Hold Response). Based on the accelerator pedal request, the engine's response may not be fulfilled on hills if the ""Auto hold"" function is activated. CAUSE DME software error"
B1101132018-11-26. Service bulletin. ENGINE. N63 AND N63T ENGINE: ENGINE OIL CONSUMPTION, ENGINE OIL TOP-UPS AND REFILL CAPACITY. Customers with one of the vehicles above may complain that the engine's oil consumption is "too high," resulting in engine oil top-ups and workshop visits to address the issue before the vehicle displays an engine oil service as being "due." When the vehicle's engine oil drops to the minimum level, a message will display in the vehicle advising the driver to "add 1 quart of engine oil." After topping up and continued operation, the "add engine oil" message may display again before an engine oil service is required and performed. CAUSE Engines that are fitted with a turbocharger, as part of their normal operation, will consume engine oil at a higher rate than a naturally aspirated engine (non-turbocharged engine). In this case, a "turbocharged" engine could require topping up of the engine oil more frequently.

0703142018-11-26. Service bulletin. EQUIPMENT. Diagnosing Stored Fault Codes to Help Avoid Repeat Repair Visits. Analysis of FASTA data and repeat repair visit reports indicates that there are many fault codes that are stored in the above vehicles, but they are not diagnosed to identify their root cause. Fault codes that are not diagnosed to find their root cause can lead to a repeat repair visit to the workshop by the customer. Where diagnosis (vehicle or short test) with ISTA has already started, it is important to diagnose the fault code(s) listed below (when they are stored in the vehicle) during the current workshop visit. This will help lead to a reduction in workshop repeat repair visits and higher customer satisfaction.
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.
