BMW NA will not provide warranty coverage to any Settlement Class Member's vehicle containing modifications or alterations to the turbocharger or its wastegates (software, hardware or otherwise), or evidencing other conditions not normally covered under the original New Vehicle/SAV Limited Warranty or applicable emissions warranty. Modifications excluded from warranty coverage include any aftermarket parts that affect the turbocharger system, or if there are other conditions that would normally exclude it from warranty coverage."
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.
2403132018-11-26. Service bulletin. ENGINE; POWER TRAIN. N52T/N55 with 8HP45: Delay in Engine Response. When slowing down to lower suburban road speeds and then accelerating, a delay in engine response may be experienced. 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.
1101132018-11-26. Service bulletin. ENGINE AND ENGINE COOLING. MService Action: Replace the Coolant Pump. Coolant is leaking from the coolant pump. CAUSE The coolant pump may develop cracks in the plastic housing. These cracks may result in a coolant leak.
2403132018-11-13. Service bulletin. POWER TRAIN; ENGINE; ELECTRICAL SYSTEM:SOFTWARE. A customer may complain of a delay in engine response after decelerating at low road speeds and then reaccelerating. This can occur when the transmission remains in a high gear due to a delay in the transmission downshifting. This situation can be more noticeable while driving on roads with slight turns or with an increasing gradient. Unfavorable EGS and DME software
1307122018-11-13. Service bulletin. ENGINE; FUEL SYSTEM, GASOLINE; FUEL SYSTEM, GASOLINE:FUEL INJECTION SYSTEM:INJECTORS. 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.

1106142018-11-13. Service bulletin. ENGINE AND ENGINE COOLING. INFORMATION This bulletin outlines the Customer Care Package program that has been designed exclusively for BMW vehicles with the N63 engine. Vehicles with the N63 high performance engine are engineered with EfficientDynamics that provides fuel economy without compromising on its "class leading" power and performance. To ensure these engines keep delivering the ultimate performance, we have designed this Care Package that includes a 6 point check, and if necessary, the replacement of one or more of the following powertrain components: ? Hot-Film Air Mass Sensors ? PIEZO High Pressure Fuel Injectors ? Engine Vacuum Pump ? Fuel System Low Pressure Sensor/Feed Line ? Fresh Air Intake Turbo Seals ? Crankcase Ventilation Lines (Hoses) This engine care package also includes a multi-point inspection of the vehicle, including tire pressures, fluid levels, safety and convenience features. The procedure described in this bulletin should be completed in conjunction with performing SI B11 16 14, N63 Engine: Check the Timing Chain. Perform all recommended, due or qualifying "time-based" maintenance service tasks as directed by the Key Reader/ISPA Light application. Note: The procedure in SI B11 16 14 includes an engine oil and filter change. When applicable, also perform the procedure described in SI B61 30 14, 12-Volt Battery Replacement under the BMW Maintenance Program together with performing the N63 Customer Care Package. After completing all necessary repairs, vehicle needs to be test driven for up to 30 minutes to assure the highest standard of performed repairs.
0104142018-11-13. Service bulletin. ENGINE AND ENGINE COOLING. External Engine Oil Leaks and Repairs. During the vehicle's operational life, normal engine oil seepage or sweating, in addition to accumulated road dust, dirt and grime in the engine compartment can cause the appearance of a more severe oil leak. This is further exaggerated by residual oil that remains on the engine assembly after maintenance services are performed, e.g., oil filter changes, "engine oil top-offs," etc. If this visual appearance of accumulated oil on the engine assembly as an "active leak" is misinterpreted, unnecessary gasket repairs/replacements will result. Specifically, our analysis of the claim-related data for vehicles equipped with the engines noted in this bulletin is showing an above-average number of engine gasket repair/replacement claim submissions. The purpose of this bulletin is to provide your workshop with information and a procedure that will help in identifying engine oils leaks that do and do not require a repair.
