Yes, Revive is extremely effective at removing sooty carbon deposits from variable geometry turbochargers (VGT). However, it cannot compensate for split vacuum pipes, mechanically worn or seized components. Prior to making a purchase carry out some basic diagnostic tests: 1. Scan for diagnostic trouble codes to identify the fault area. 2. Check for vacuum leaks in related solenoids and actuators. 3. If you are unsure seek advice from an ASE certified technician. Your shop may recommend trying Revive first, rather than going down a more expensive repair route.
