Service bulletin SI-B12-22-10

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.

A rattling noise can be heard from the engine compartment; the engine has a loss of power; and the Service Engine Soon lamp is illuminated. One or more of the following faults may be stored. 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.
110208	2019-07-09. 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."
170209	2018-12-17. Service bulletin. "Oil Leak from Turbocharger Charge Air Hose. The customer may complain of an oil leak from the engine area. The ""Service Engine Soon"" lamp may also be illuminated with fault code ""4674 - FMO injection quantities-observer"" stored. CAUSE The molded seal in the charge air pipe may have been cut by debris abrasions, causing an external leak of air and oil in the charged air system of the turbocharger. An improved seal has been developed to correct this issue."
