B611305	2020-11-16. Service bulletin. Discharged Battery Energy Diagnosis Must Be Performed: The electrical system of BMW vehicles has been subject to an ongoing development process over the last few years. This has led to increased demands being placed on the battery. This document covers important information for the dealer on how to handle "discharged battery" complaints. In order to properly repair the vehicle the first time in the workshop, it is very important that the diagnostic test plans are performed to completion, with all results taken into consideration. Without performing the energy diagnosis test plan, the root cause of the discharged battery cannot be identified. This increases the chances of a repeat repair.

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."
