B0703142018-12-10. Service bulletin. ENGINE; STEERING; ELECTRICAL SYSTEM; EQUIPMENT. This Service Information bulletin supersedes SI B07 03 14 dated October 2015. Diagnosing Stored Fault Codes to Help Avoid Repeat Repair Visits. Fault codes stored in vehicles being serviced are not being diagnosed, leading to repeat repair visits (source- Analysis of FASTA data and repeat repair visit reports). INFORMATION 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) to find their root cause during the current workshop visit. This will help lead to a reduction in workshop repeat repair visits and higher customer satisfaction.
1217132018-12-03. Service bulletin. ENGINE; POWER TRAIN. N55: Engine Difficult to Start at Cold Ambient Temperatures. The complaint may include any of the following symptoms: * The engine stalls immediately after a cold start before driving away * The engine may run roughly or misfire after a cold start * The engine does not start cold or may take several attempts * To assist starting when cold, the accelerator may need to be depressed slightly and the idle speed raised for a few seconds so the engine does not stall This can occur most frequently at outside ambient temperatures between -15°C and + 15°C. It is possible that the Service Engine Soon (MIL) lamp is on with misfire fault(s) stored, but it is equally possible that there will be no faults stored in the DME. Unfavorable DME software Cold start or idling problems may arise due to poor fuel quality. The use of summer fuel during cold outside temperatures may also lead to such problems.
1216112018-12-03. Service bulletin. ENGINE; POWER TRAIN. N55 Engine Failsafe - FC 120308 Boost Pressure Control, Plausibility: Pressure Too Low Stored in DME Fault Memory. INFORMATION The customer complains the SES is illuminated and the engine has reduced power (engine failsafe mode).
0102122018-12-03. Service bulletin. ENGINE; EQUIPMENT; EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL. "BMW NA has agreed to extend the emissions warranties of the turbocharger's wastegate to: ??8 years or 82,000 miles, whichever occurs first, as determined from the vehicle's original in-service date select the ""Vehicle Comment"" button to display the extended coverage information. The terms of the original New Vehicle/SAV Limited Warranty and applicable emissions warranty still apply. 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."
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)."
1205132018-11-26. Service bulletin. ENGINE. Service Engine Soon Light Flashes with Throttle Adaptation Faults Stored. The EML light flashes with a check control message for reduced power output and/or the Service Engine Soon lamp (MIL) flashes. During the throttle valve adaptation (teach-in limit run), faults may occur due to signal voltage oscillations. This could lead to a termination of the teach-in routine or an incorrect value taught in at the lower limit. The following faults can be stored in the DME memory: E82, E84, E88, E89, E92, and E93 BN2000 vehicles * 28D0: throttle valve, adaptation: Initial adaptation, lower limit not taught in * 28D4: throttle valve, adaptation: Subsequent teach-in, lower limit not taught in * 28C4: throttle valve, adaptation: Emergency air position not adapted * 28A0: throttle valve angle - Intake manifold absolute comparison: pressure too high ??3166: Tank-ventilation system: fault F01, F02, F06, F07, F10, F12, F13, F30, F31, and ALPINA B7 BN2020 vehicles: * 101408: throttle valve, adaptation: Initial adaptation, lower limit not taught in * 107AE0: throttle valve, adaptation: Subsequent teach-in, lower limit not taught in * 101402: throttle valve, adaptation: Emergency air position not adapted * 101F01: throttle valve angle - Intake manifold absolute comparison: pressure too high ??190F08: Tank-ventilation system: fault Sensitivity of the throttle valve sensor (only affects parts installed during this production period)
1215142018-11-13. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION; ELECTRICAL SYSTEM:SOFTWARE; ENGINE. N55 with Double-Clutch Transmission: Idle Fluctuates when Stopped. A customer may complain that after coming to a stop, the engine speed intermittently fluctuates from about 500 RPM to 1,100 RPM. This situation can be more noticeable when the air conditioner is on. Unfavorable DME software.
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.
1238142018-11-13. Service bulletin. FUEL SYSTEM, GASOLINE:FUEL INJECTION SYSTEM; ENGINE. SUBJECT N20, N26, and N55 Engines with Injector Electrical Faults. Any of the following symptoms could occur simultaneously with injector electrical faults stored in the DME: z After the engine is turned off for a short time, it can no longer be started; however, the starter motor turns. z The engine starts but immediately cuts off. z The engine runs erratically or lacks power. z The Service Engine Soon light (MIL) may be on with several poetential faults stored. The DME has malfunctioned due to an internal fault.
1204152018-11-13. Service bulletin. ELECTRICAL SYSTEM; ENGINE. SUBJECT DME Internal and Valvetronic Faults Set at Cold Ambient Temperatures. The Service Engine Soon light (MIL) can be illuminated with the erroneous internal and Valvetronic faults stored in the DME. The MIL will only come on if the fault has been detected on two (or more) consecutive drive cycles. The following fault codes may be stored in the DME: E Seriesz 36AE - DME, internal fault, Valvetronic: Current implausible One or more of the following secondary faults may also be stored: z 2DE2 - Valvetronic, actuation, voltage phase: Line disconnection z 2DE3 - Valvetronic, actuation, volt phase: Line disconnection z 2DE4 - Valvetronic, actuation, volt phase: Line disconnection F Seriesz 1F0905 - DME, internal fault, Valvetronic: Current implausible One or more of the following secondary faults may also be stored: z 135B10 - Valvetronic, actuation, voltage phase: Line disconnection z 135B11 - Valvetronic, actuation, volt phase: Line disconnection z 135B12 - Valvetronic, actuation, volt phase: Line disconnection Engine performance and driving characteristics are not affected.
