What It Is Used For

• Restoring variable valve timing control when the original solenoid is failing
• Addressing cam timing-related fault codes on Audi engines
• Correcting rough idle or drivability issues tied to VVT operation
• Supporting proper engine response during acceleration and load changes
• Replacing a worn or electrically faulty VVT solenoid

Installation Notes and Tips

Verify connector style, terminal count, and engine application before installation. This part uses a 12V electromagnetic design with a female connector and blade terminals, so matching the OE connector and engine code is important. Inspect the sealing surface and related oil passages during service, since no gasket is included. Confirm fitment for your specific Audi A3, A4, A5, A6, Q3, Q5, or Q7 by year and engine notes before ordering.

Quality Assurance

Standard Ignition supplies replacement engine management components for service applications, and VVT857 is built to match the electrical and connector requirements of the listed vehicles. Use the confirmed fitment data to select the correct part for your Audi variable cam timing or variable valve lift system.
