Purpose and function in the timing system

The described solenoid control valve operates within the camshaft phasing control area in 1.5 TSI and 1.5 TFSI engines used in models such as the VW Golf SV and Audi A3 8V. Its task is to precisely dose oil to the variable valve timing mechanism, which enables smooth adjustment of the camshaft position relative to the crankshaft.

A functional component of this type contributes to:

• stable idle speed and reduction of engine vibrations,
• proper dynamics during acceleration across the full rev range,
• efficient use of the air-fuel mixture, which supports economical operation,
• maintaining engine operation in accordance with the engine control unit (ECU) maps.

Construction and technical characteristics

As a component from the Camshafts group, the camshaft solenoid control valve works directly with the oil system and the engine controller. The design features an integrated body with a hydraulic part and a control section, which allows for rapid response to signals from the ECU and stable maintenance of the set camshaft adjustment angles.

The solution used by Volkswagen OE ensures:

• precise fitment into the cylinder head socket without the need for modifications,
• appropriate oil flow characteristics for 1.5 TSI/TFSI engines,
• compatibility with factory engine control software.

Condition of the component and installation aspects

The offered camshaft solenoid control valve is in used condition, meaning it has been removed from a vehicle and is intended for users looking for an economical solution while maintaining the manufacturer's original specifications. This type of component is particularly useful for timing system repairs when it is necessary to restore the correct operation of variable valve timing without investing in a new part.

During installation, it is recommended to:

• apply the appropriate tightening torque in accordance with the service documentation for the specific model,
• check the cleanliness of the oil channels in the cylinder head before installation,
• verify the condition of the engine oil and adhere to its change intervals to ensure proper valve operation.

Benefits of using an original Volkswagen solution

Using a camshaft solenoid control valve compliant with Volkswagen OE solutions allows for maintaining the factory operating parameters of the 1.5 TSI/TFSI unit. In practice, this means:

• maintaining proper engine refinement across the entire rev range,
• reducing the risk of ECU errors related to incorrect camshaft position,
• better repeatability of diagnostic results when using service testers,
• consistency with other components of the timing and lubrication system.
