EGR System Vacuum Radiator Actuator – VAG 1.6 TDI / 2.0 TDI | OEM 03L131512CF
The vacuum radiator actuator controls the EGR cooler bypass valve on VAG 1.6 TDI and 2.0 TDI engines. When it fails, the EGR radiator bypass stops working correctly — causing EGR fault codes, incorrect exhaust gas temperatures, and reduced EGR efficiency. This direct replacement actuator restores correct EGR system operation.
Fits OEM #03L131512CF.
