VDO Gauges S119566001Z Valvetronic Eccentric Shaft Sensor

The VDO S119566001Z Eccentric Shaft Sensor is a critical engine management component designed for BMW vehicles equipped with the Valvetronic variable valve lift system. This sensor monitors the position of the eccentric shaft and transmits precise angle data to the engine control unit (ECU), enabling optimal valve timing and efficient engine operation.

Key Features:

• OEM-quality sensor manufactured by VDO Continental, a leading supplier of original equipment automotive electronics
• Monitors eccentric shaft position to ensure proper variable valve lift operation
• Dual sensor design for redundancy and accuracy verification by the ECU
• Direct replacement for BMW OEM part number 11377527017
• Helps prevent engine misfires, rough idle, hesitation, and hard starting conditions

Common Failure Mode:

This sensor is a commonly failed component due to oil contamination from a deteriorated valve cover seal. When oil leaks into the electrical harness, it can cause Valvetronic system faults, trigger the check engine light, and result in poor engine performance or limp mode operation. If you notice oil inside the sensor connector or on the valve cover near the sensor, replacement is recommended along with a new valve cover seal.

Installation Note:

The eccentric shaft sensor is mounted to the cylinder head beneath the valve cover. Replacement requires valve cover removal for proper access to the mounting fasteners.
