Variable Geometry Turbo (VGT) Repair in Hyderabad
Specialists in variable vane turbocharger diagnosis and repair
Variable Geometry Turbos (VGT), also known as Variable Nozzle Turbos (VNT), feature adjustable vanes that optimize turbo performance across the entire engine RPM range. This technology eliminates turbo lag while maintaining high-end power, but the complex vane mechanism requires specialized service. At Metre Per Second, we are Hyderabad's VGT specialists with extensive experience on Garrett VNT, BorgWarner VTG, and other variable geometry systems. Common issues include stuck vanes from carbon buildup, worn vane bushings, and actuator problems. We provide complete VGT services from ultrasonic vane cleaning to complete turbo reconditioning. Proper VGT function is essential for performance, fuel economy, and emission compliance.

Frequently Asked Questions — Turbo Repairs in Hyderabad
Why do VGT vanes stick?
Soot and carbon from combustion accumulates on vanes, especially in diesel engines. Short trips and excessive idling worsen buildup. Regular highway driving helps keep vanes clean.
Can stuck vanes be cleaned without turbo removal?
Sometimes yes, using cleaning sprays or solvent flush. However, severe sticking requires turbo removal for thorough ultrasonic cleaning.
How often should VGT be cleaned?
We recommend inspection every 60,000 km. Cleaning may be needed depending on driving patterns and engine condition.
Is VGT delete a solution?
VGT delete eliminates variable geometry but results in turbo lag and may cause emission compliance issues. We recommend proper repair instead.
