• Loss of factory-style turbocharger performance on listed vehicles

Installation Notes and Tips

Verify hose routing, connector style, and mounting location against the original solenoid before installation. This unit uses three 0.25-inch hose connections, a blade terminal, and no wiring harness, so the existing vehicle harness and vacuum lines must match the OE layout. Confirm application details by year, make, and model, especially on Audi A4, A4 Quattro, and Volkswagen GTI or Jetta variants where multiple engine configurations may exist.

Quality Assurance

Dorman designs this boost solenoid to match original fit and function on the listed applications and to provide reliable performance and durability in turbocharged systems.
