Service bulletins for the 2007 BMW Z4

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.

B1102082020-10-19. Service bulletin. ENGINE AND ENGINE COOLING. 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.
1102082019-07-09. Service bulletin. EQUIPMENT; ENGINE. "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."
B1106162018-12-10. Service bulletin. EQUIPMENT; ENGINE. N51, N52, N52K and N52T Engines: Various Eccentric Shaft Sensor Faults stored in the DME - Diagnostic Hints This Service Information bulletin and attachment supersedes SI B11 06 16 dated April 2016.. The customer may complain about one of the following: Rough engine running Engine cannot be started (crank no start) Check Engine Light illuminated One or more of the following faults may be stored in the DME: 2A37 - Valvetronic, eccentric shaft sensor plausibility 2A47 - Valvetronic, eccentric shaft, signal plausibility 134E08 - Eccentric shaft plausibility (on F10, F25 vehicles only) CAUSE The VVT eccentric shaft sensor connector, and/or DME connector may have oil contamination due to oil leakage at the VVT sensor gasket.

The customer may complain about one of the following: Rough engine running Engine cannot be started (crank no start) Check Engine Light illuminated One or more of the following faults may be stored in the DME: 2A37 - Valvetronic, eccentric shaft sensor plausibility 2A47 - Valvetronic, eccentric shaft, signal plausibility 134E08 - Eccentric shaft plausibility (on F10, F25 vehicles only) CAUSE The VVT eccentric shaft sensor connector, and/or DME connector may have oil contamination due to oil leakage at the VVT sensor gasket.
1109072018-12-03. Service bulletin. ENGINE. Intermittent Hydraulic Valve Adjuster (HVA) Noise. An occasional ticking or rattling noise from the camshaft hydraulic valve lifters (HVA) may occur during cold engine starts, due to frequent short-distance driving, or the noise may occur for an extended period of time even though the engine is at operating temperature. Improved parts were phased into production beginning on 10/1/2008 and fully implemented on November 31st 2008.
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.
