Turbo Wastegate Repair Kit - BMW N63 4.4L V8 - MGT2256S

This repair kit is for the turbocharger wastegate mechanism on the listed BMW N63 4.4L V8 twin-turbo applications. Wear in the pressure-relief flap and linkage can affect boost control; inspect the turbocharger and wastegate before selecting the repair.

Applications

• BMW 550I, 650I, 750I, X5 and X6 with N63 4.4L V8 twin-turbo engine - 2008-2015.

Turbocharger Selection

Turbocharger designation: Garrett MGT2256S. Additional listed designation: GT2256S. Match the marking and wastegate mechanism on the installed turbocharger.

When to Inspect the Wastegate

• Rattling from the exhaust manifold area.
• Increased fuel consumption or reduced acceleration.
• Low-boost faults during sustained hard acceleration above 90 km/h, sometimes without a Check Engine light.
• Low-boost-pressure faults.
• Misfire faults at high engine speed.

The mechanism can show wear around 100 000 km, but mileage alone does not establish its condition. Diagnose these symptoms and inspect the linkage before replacement.

Repair Scope

The product is a wastegate repair kit, rather than a complete turbocharger. Heat cycles and contamination around the rods are reasons to inspect the mechanism for wear.

Important Before Ordering

Compare the original part number, marking, shape and mounting design before ordering. A model name alone does not confirm the required version.
