Camshaft Solenoid Valve – Audi A8 D4 S8 – 2010-2018 – 06E109257T

This direct-fit VVT camshaft valve position sensor (variable valve timing solenoid / camshaft phaser solenoid) restores smooth variable valve timing and full engine performance on the Audi A8 D4 (2010–2018). Built to OEM specification and matching part numbers 06E109257, 06E109257T, 06E109257S, 06E109257N and 06E109257M. Also fits equivalent Volkswagen models.

Common signs of failure

A failing VVT solenoid or oil control valve typically triggers the check engine light with codes P0010, P0011, P0014 or P0017 (intake/exhaust camshaft position and actuator circuit faults). Drivers report rough idle, hesitation under acceleration, reduced power, a distinct rattle from the top of the engine on cold start that fades as oil pressure builds, poor fuel economy, and in some cases the vehicle dropping into limp mode. Ignoring the fault can lead to timing chain wear.

Fitment notes

Plug-and-play installation, no diagnostic coding required. The solenoid controls oil flow to the camshaft phaser, so a worn or clogged unit causes the cam timing to lag — producing the symptoms above. Replacement is typically a short job: drain a small amount of oil, undo the retaining bolt, swap the solenoid, refit and clear codes. Standard 2 pin connector.

Frequently asked questions

Can I drive with a P0010 or P0011 fault code?

Short distances yes, but extended driving with a failed VVT solenoid will accelerate camshaft and timing chain wear because the cam timing is no longer optimised. Replace the solenoid promptly to avoid much costlier repairs.

Do I need to use OEM oil after fitting?

Use the engine's specified oil grade and change it on schedule — VVT solenoids fail most often because of dirty or sludged oil. Fresh oil at the correct viscosity is essential.

Will it fix a rattle on cold start?

Yes, if the rattle is caused by delayed phaser engagement due to a faulty solenoid. If the rattle persists after fitting, the camshaft phaser itself may also need replacement.
