Detailed Description

Use the Spectra VTS1146 when servicing variable valve timing systems on compatible Audi and Volkswagen vehicles. This solenoid is designed to regulate oil flow for cam timing adjustment, which is critical for smooth engine performance, drivability, and emissions control. This part cross-references Standard Ignition VVT214 for the same application.

Compatible With 2013-2017 Audi Q5, 2012-2015 Audi A6 Quattro, and 2011-2015 Volkswagen Touareg, with additional coverage for select Audi A7 Quattro, A8 Quattro, S4, S5, S6, S7, S8, SQ5, RS3, RS7, and Q7 applications. Spectra VTS1146 is also listed for several 2016 cylinder-head valve-only applications on Audi models.

What It Helps Address

• Rough idle caused by inconsistent cam timing control
• Check engine lights related to VVT solenoid performance
• Reduced fuel economy from improper valve timing operation
• Emissions concerns tied to timing system faults
• Engine hesitation or poor throttle response during acceleration

Installation Notes and Tips

Verify the OE part number and engine configuration before installation. On some Audi applications, fitment is limited to valve-only use in the cylinder head, so confirm the notes for your exact vehicle. Inspect the connector, oil passages, and surrounding timing components during service to help ensure proper operation after replacement.

Quality Assurance

Spectra builds its VVT solenoids with controlled manufacturing and quality checks to support reliable engine performance and consistent operation in daily driving conditions.
