Turbocharger Wastegate Repair Kit - BMW X5 M E70 / X6 M E71 S63B44 - 11657848115

The wastegate mechanism controls exhaust bypass flow through the turbocharger on BMW X5 M E70 / X6 M E71 S63B44. Wear in its shaft, bushing or lever can cause play, rattling, sticking and unstable boost. This kit addresses the mechanical wastegate fault when the rest of the turbocharger remains serviceable.

Selection and Repair Limits

Compare the installed turbocharger number. The same engine can use different turbocharger and wastegate versions. Inspect the turbo housing, bushing seat, shaft, lever, actuator and bypass flap before repair. Mechanical wear can be repaired separately from the complete turbo only when the remaining components are serviceable.

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.
