Think TechSmart First: Direct Replacement

The Problem: On certain Audi and Volkswagen vehicles with 2.0T engines, a faulty wastegate frequency control valve can cause the vehicle to enter limp mode or develop zero boost, severely effecting drivability.

Our Response: TechSmart’s Wastegate Frequency Control Valve is a direct replacement for the failed OE part. Once installed, the valve will help resolve boost pressure and drivability issues. It covers more than 600,000 VIO.

TechSmart Tip: Before you put on a new valve, check the attached rubber hoses for leaks.
