Actuator Camshaft / VVT Solenoid – Porsche Cayenne 955 S /
Turbo (2005>>)
OEM ref: 94810530407
This camshaft actuator (variable valve timing / VVT solenoid) controls the oil flow to the camshaft adjuster, allowing the engine ECU to advance or retard cam timing. On Porsche Cayenne 955 S and Turbo models from 2005 onwards, a healthy actuator is essential for smooth power delivery, good fuel economy and clean emissions.

Why these should be replaced
Over time the original actuator is exposed to hot engine oil, varnish deposits and general wear. This can cause the internal valve to stick or slowdown, which means the cam timing can no longer be adjusted correctly. Replacing tired actuators:
Restores correct camshaft timing and engine performance Improves throttle response and mid-range torque Helps cure rough idle and hesitation under load Can reduce fuel consumption and emissions Prevents further damage to camshaft adjusters and associated components
On many Cayenne V8 engines, Porsche and independent specialists recommend replacing faulty VVT solenoids in pairs (one per cylinder bank) to ensure balanced timing and avoid repeat labour costs.
Common issues / symptoms of a failing camshaft actuator
Typical signs that this part needs replacement include:
Check Engine Light with camshaft timing faults (e.g. “camshaft position – timing over-advanced/retarded”) Rough idle, misfires or stalling, especially when hot Flat spots or loss of power in the low–mid rev range Poor fuel economy compared with normal Rattling / ticking on start-up if the timing cannot be adjusted correctly Fault codes relating to Variable Valve Timing (VVT) solenoid / camshaft actuator
If these symptoms are present and other basic checks (oil level/quality, wiring, connectors) are OK, the camshaft actuator is a prime suspect.
