Reinforced 316 Stainless Steel Wastegate Actuator Arm for Alfa Romeo Giulia / Stelvio 2.0T (All Model Years)
This component is a direct replacement for the original actuator arm, which is not sold separately by Alfa Romeo.
The most common reason for replacement is the widespread issue associated with DTC P0299 (Turbo Underboost Condition). This is often caused by wear in the factory wastegate arm, which can lead to slack, oval-shaped mounting holes, and a weakened connection between the actuator and the turbocharger. As a result, the wastegate may not fully close, causing a loss of boost pressure and reduced engine performance.
This upgraded actuator arm is precision-engineered for a secure fit and smooth operation that meets or exceeds OEM specifications. Manufactured from 316 stainless steel, it offers exceptional corrosion resistance and long-term durability.
Key Features:
Compatible with Alfa Romeo Giulia / Stelvio 2.0T (All Years)
Made from high-strength 316 stainless steel
Designed to resolve one of the most common causes of DTC P0299
Helps restore throttle response and boost stability
Important: While replacing the wastegate arm does not guarantee resolution of all causes behind code P0299, it is a highly common and effective fix. It is recommended to inspect the actuator-to-turbo linkage for slack or play before replacement.
