Service bulletin 130409

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

"N54 - 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)."

B1102082020-10-19. Service bulletin. Power Reduction, FC2A82 Intake VANOS and/or FC2A87 Exhaust VANOS Camshaft Fault: The ?Service Engine Soon? (MIL) lamp is illuminated and engine power reduction is perceived. This situation can occur after driving for some time with the engine at full operating temperature. If theignition is cycled, the engine then usually performs normally.
B1306192020-01-21. Service bulletin. SERVICE ACTION: N54T ENGINE - INSPECT AND REPLACE INJECTOR(S). The piezo-type fuel injectors may cause a rough running at start-up or rough running while at idle.

The Service Engine Soon (MIL) lamp could come on with one or both of the following faults stored in the DME: * 29F4: catalytic converter conversion - bank 1 * 29F5: catalytic converter conversion - bank 2 DME software diagnostic error.
1212102019-07-10. Service bulletin. "Engine Idle Speed Dips Too Low While Braking at Lower Vehicle Speeds. The engine speed may drop too low when slowing to a stop, braking at low road speeds, or while parking the car. This occurs intermittently, but can be more apparent when the automatic transmission selector lever is in the ""Sport mode"" position. Unfavorable DME software application"

E70, E71, E82, E88, E90, E92 and E93: 2D5A - VANOS, intake: control fault, camshaft sticking 2D5B - VANOS, intake: control fault, position not reached 2D60 - VANOS, exhaust: control fault, camshaft sticking 2D61 - VANOS, exhaust: control fault, position not reached 2D9F - camshaft input sensor: signal implausible 2DA1 - Camshaft exhaust sensor: signal implausible 300C - Camshaft input sensor: signal high 300D - Camshaft input sensor: signal low 300E - Camshaft exhaust sensor: signal high 300F - Camshaft exhaust sensor: signal low F07, F10, F12, F13 and F25: 130104 - VANOS, intake: control fault, camshaft sticking 130108 - VANOS, intake: control fault, position not reached 130304 - VANOS, exhaust: control fault, camshaft sticking 130308 - VANOS, exhaust: control fault, position not reached 130E11 - Camshaft input sensor: signal implausible 130F11 - Camshaft exhaust sensor: signal implausible 164020 - Camshaft input sensor: signal high 164021 - Camshaft input sensor: signal low 164030 - Camshaft exhaust sensor: signal high 164031 - Camshaft exhaust sensor: signal low CAUSE One or both (intake and/or exhaust) of the VANOS gear assemblies have failed; the attaching bolts may have also loosened and/or broken.
1102082019-07-09. Service bulletin. "Power Reduction, FC 2A82 Intake VANOS and/or FC 2A87 Exhaust VANOS Camshaft Faults are Stored in DME. The ""Service Engine Soon"" (MIL) lamp is illuminated and engine power reduction is perceived. This situation can occur after driving for some time with the engine at full operating temperature. If the ignition is cycled, the engine then usually performs normally. The following faults are stored in the DME: * 2A82 VANOS intake - stiff; jammed mechanically * 2A87 VANOS exhaust - stiff; jammed mechanically * 130108 VANOS intake: control fault, position not reached * 130308 VANOS exhaust: control fault, position not reached For the N54 engine, the following secondary faults may also be stored: * 120408 Charge-air pressure control, cut-out: Boost pressure accumulation blocked * 3100 Boost-pressure control, deactivation - boost-pressure buildup prohibited CAUSE The VANOS faults can be caused by an insufficient oil pressure supply to the inlet VANOS adjustment unit. To effectively move the camshafts to the target positions in the specified time and under all engine conditions, sufficient oil pressure supply to the VANOS control pistons must always be available. If engine operation requires the VANOS system to quickly advance or retard the intake or exhaust camshaft, faults may be stored if the camshaft is ""late"", or does not reach the target position. In this situation, engine power may be reduced and a check control message is displayed. The consequential fault 3100 or 120408 can also be set in the DME fault memory as well."
