JL 06L-109-257F Variable Valve Timing VVT Camshaft Adjustment Solenoid Valve

The JL 06L-109-257F is a replacement Variable Valve Timing (VVT) Camshaft Adjustment Solenoid Valve — also known as an Oil Control Valve (OCV) — designed to restore proper camshaft timing control on compatible VW, Audi, Skoda, and SEAT engines. This solenoid is a direct-fit replacement for OEM part number 06L 109 257 F.

The camshaft adjustment solenoid works by directing pressurized engine oil flow to the variable valve timing actuator on the camshaft. The engine control module (ECM) sends a signal to the solenoid to advance or retard camshaft timing, optimizing engine performance, fuel efficiency, and emissions across all RPM ranges. A faulty or failing solenoid can trigger diagnostic trouble codes related to camshaft position and timing, resulting in rough idle, reduced power, or poor fuel economy.

Key Features:

• Direct OEM replacement for part number 06L 109 257 F
• Controls camshaft timing by regulating hydraulic oil flow to the VVT actuator
• Restores proper variable valve timing operation and eliminates related fault codes
• Compatible with select VW, Audi, Skoda, and SEAT vehicles equipped with 1.8T and 2.0 TFSI engines
• Manufactured to meet OEM fit, form, and function requirements

This solenoid is an essential engine management component. When replacing, ensure the engine oil is clean and at the correct level, as contaminated oil is a leading cause of OCV failure. Professional installation is recommended.
