06L-109-259-D Genuine VW/Audi Camshaft Adjuster Magnet

Genuine VW/Audi Camshaft Adjuster Magnet

06L-109-259-D is the electrical actuator used at the camshaft adjustment valve on selected Volkswagen and Audi gasoline engines. It converts an engine-management command into movement at the camshaft control mechanism, supporting the engine's hydraulic valve-timing adjustment. Order by the exact engine and original actuator revision: similar-looking engines can use different valve locations, connectors and sealing arrangements.

Technical Details and Operation

The camshaft adjuster magnet is the external electromagnetic actuator. The hydraulic control valve and mechanical camshaft adjuster are separate components. The archive photograph shows the round actuator housing, mounting holes, electrical connector and Genuine VW/Audi packaging labeled 06L-109-259-D. This listing supplies one magnet; the required quantity and its intake or exhaust location depend on the engine.

• Part number: 06L-109-259-D.
• Manufacturer: Genuine VW/Audi.
• Function: electromagnetic actuation of the camshaft oil-control mechanism.
• Quantity supplied: one camshaft adjuster magnet.
• Revision information: public factory catalogs list 06L-109-259-A as a replaced reference. Earlier 06J-109-259-A installations can require both the updated magnet and connector housing 4H0-973-702-A.

Important Connector and Application Notes

When replacing an earlier actuator, inspect the existing electrical connector before installation. The published conversion from 06J-109-259-A calls for the newer magnet together with connector housing 4H0-973-702-A where the vehicle has not already been updated. That housing is sold separately. Do not force an incompatible connector onto the new actuator. Match the original valve location and sealing arrangement, and verify any production-date split against the vehicle identification.

Common Reasons to Replace

Replacement is appropriate when testing identifies an electrical actuator fault, damage to the housing or connector, or a failure of actuator operation. Timing-control faults may appear as a check-engine light, slow camshaft response, hesitation or unstable engine operation. These symptoms do not identify the magnet by themselves: wiring, engine oil condition, the separate control valve and mechanical timing system can also cause a commanded-versus-actual timing error. Inspect the surrounding seal if oil leakage is present, because a seal repair may be required alongside or independently of the actuator.

Detailed Fitment Table

Each row retains its confirmed engine, year and body restrictions. An engine code applies only to the years and configurations in that row. Where the catalog identifies the engine family without an engine code, compare the original actuator and confirm the installation by VIN. This part is for the specified gasoline timing-control applications; a model-name match alone does not establish fitment for diesel, hybrid or other engine variants. Connector conversion requirements above apply wherever an earlier actuator is being replaced.

Installation and Verification

Use the factory repair procedure for the exact engine and actuator location. Keep the control-valve area clean, inspect the receiving surfaces and replace any seals or fasteners required by the procedure. Use the specified tightening sequence and torque. After installation, inspect for oil leakage, verify the connector is secure and check commanded and actual camshaft operation as directed by the repair information. A separate spool valve, camshaft phaser, connector conversion housing, wiring harness and service seals are not included with this individual magnet.
