Audi Engine Variable Valve Timing (VVT) Adjuster - Kolbenschmidt 50056003

Product Information

The engine variable valve timing (VVT) adjuster is a precision component mounted on the camshaft that regulates the timing of valve opening and closing to optimize engine performance. By adjusting camshaft phasing, the VVT adjuster improves power output, fuel efficiency, and emissions control under varying driving conditions. Typically controlled by oil pressure and an electronic solenoid, it plays a critical role in maintaining smooth engine operation and responsiveness.

• Rough idle or reduced engine performance – caused by improper valve timing control.
• Illuminated check engine light (CEL) – often accompanied by diagnostic trouble codes (DTCs) related to camshaft timing.
• Rattling or knocking noise from the engine – a sign of worn or failing adjuster components.
