VNT actuator KP39A BEW vw jetta golf 1.9 tdiNew replacement actuator for 2004 2006 1. 9tdi BEW engines equipped with KP39A turbo. This is a puller vacuum actuator with position sensor. When a check engine light and limp mode affects your ride, this part is the culprit. The diaphragm inside fails and VNT stops moving. For years, a replacement actuator wasn't available so the only solution was a complete new turbo. Now you can replace only what's broken and save!
