Turbocharger For Mercedes Benz ML GL GLE 802774-5008S A6420901686 AL-0073

Premium Electronic VNT Turbocharger for Mercedes-Benz ML, GL, GLE | Garrett GTB2060VK OM642

Restore the smooth, effortless torque, high highway fuel economy, and refined acceleration of your luxury SUV with this premium Variable Nozzle Turbine (VNT) Turbocharger Assembly. Specifically engineered for Mercedes-Benz's widely acclaimed 3.0L V6 OM642 diesel engine platform, this high-precision forced-induction assembly fixes issues like low-end engine lagging, chronic oil smoke emissions, and electronic actuator faults.

This complete component features Garrett's advanced generation variable geometry architecture and serves as a direct drop-in factory replacement matching Garrett manufacturer part number 802774-5008S (including variations like 802774-0004, 802774-0005, and 802774-5001RS), Mercedes OEM cross-reference A6420901686 (or A6420901186), and market stock reference AL-0073. It comes equipped with a pre-calibrated electronic rotary actuator that continuously adjusts internal vane angles via the ECU to match throttle depth seamlessly.

• Part Cross-References: 802774-5008S | 802774-5004S | 802774-0005 | A6420901686 | 6420901686 | A6420901186 | 6420901186 | AL-0073.

• VSR High-Speed Balanced: The core rotating assembly is precision balanced on standard Vibration Sorting Rigs (VSR) to guarantee quiet cabin operation and prevent premature fluid dynamic bearing wear.

• Advanced Thermal Metallurgy: The turbine casing and variable nozzle ring are cast using premium high-nickel alloys to endure extreme exhaust gas temperatures (EGTs) without vane sticking.

Critical Benefits for Your Mercedes 3.0L V6 Diesel

The OM642 V6 diesel engine relies on precise coordination between its mass airflow sensors, EGR loops, and electronic turbo actuator. If the internal variable vanes get clogged with carbon or the electric actuator gear breaks down, the car will suffer from severe lag under 2000 RPM, fail emissions tests, or drop into a restrictive "Limp Home" mode. Upgrading with this VSR-calibrated turbocharger ensures:

1. Immediate Power Recovery: Re-establishes factory-spec transient boost targets, maximizing low-end pull and high-speed highway overtaking capability.

2. Excellent Fluid Containment: Employs premium internal piston ring seals to safeguard against engine oil pushing past the shaft and fouling your front intercooler or DPF exhaust filters.

3. Perfect ECU Synchronization: The integrated electronic actuator aligns flawlessly with original factory settings, avoiding diagnostic trouble codes (DTCs) related to boost variations.

4. Flawless Drop-in Fitment: Built to strict original blueprints to bolt directly onto the central exhaust manifold collector V-mounts, intake paths, and factory plumbing lines.
