Detailed Application Overview

The Vaico V10-4821 is used in variable valve timing systems to regulate oil flow to the actuator circuit, helping the engine management system control cam timing as commanded. For Volkswagen Jetta and Volkswagen EuroVan service, this OE-grade solenoid is a direct-fit style replacement identified by the V10-4821 part number and related OE references. If you are sourcing a Volkswagen Jetta VVT solenoid or a Volkswagen EuroVan oil control valve replacement, this part number is the key match to verify.

This part cross-references Dorman OE Solutions 918-137 for the same application.

What This Part Helps Address

• Check engine light related to variable valve timing control
• Rough idle caused by inconsistent cam timing control
• Loss of power from delayed or incorrect valve timing response
• Oil control valve or VVT solenoid fault codes on Volkswagen engines
• Driveability issues tied to exhaust-side timing control on EuroVan applications

Installation Notes and Tips

Verify the part number, OE reference, and engine application before installation. Confirm the connector style, mounting location, and system layout against the removed component, especially on 2002-2003 Volkswagen EuroVan exhaust-side applications. Clean the mating surfaces and inspect the oil passages and electrical connector for contamination or damage before installing the new solenoid.

Quality Assurance

VAICO OE-grade parts are built for European vehicle service and application-specific replacement. The V10-4821 is listed with OE reference coverage and fitment data for Volkswagen Jetta and Volkswagen EuroVan models, supporting accurate parts selection for engine timing control repair.
