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.
1201132018-12-03. Service bulletin. ENGINE; POWER TRAIN:AUTOMATIC TRANSMISSION. MN16 Engine: FC 2D9B Knock Sensor, Signal Is Stored in the DME. Certain areas of the US experience extremely cold climate conditions during the winter months, which can cause the Service Engine Soon lamp to illuminate while the engine temperature is increasing to full operating temperature. The following fault may be stored in the DME: ??FC 2D9B Knock Sensor, Signal CAUSE Unfavorable DME knock sensor diagnostic at outside ambient temperatures below -5° C
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.
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).
1215132018-12-03. Service bulletin. ENGINE. N20 and N26 Engine: Various VANOS System Faults Stored in DME. 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.
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)
