BMW N20 / N26 Turbocharger - 11657635803 (Used, Tested, 99,000km)
Overview
Used BMW N20 / N26 Turbocharger - 11657635803 — genuine OEM Mitsubishi-built TD04LR6 turbocharger fitted to the F-chassis 2.0L turbo petrol cars. Tested working before removal from a running vehicle at 99,000 km. A common wear item — N20 turbos are known for wastegate rattle, oil seal failure causing blue smoke on start-up, and reduced boost / limp mode after high mileage.
Important — production date: This is the pre-07/2012 pneumatic wastegate version. From 07/2012 onwards BMW switched to an electronic wastegate which uses a different turbocharger (not interchangeable). Please verify your vehicle's production date before fitment.

Condition
This is a used genuine OEM part. It has been tested working before removal from a running vehicle with 99,000 km on the clock. Standard wear consistent with a unit of this mileage — the shaft has been hand-spun and checked for excessive play. New oil feed gasket / seals and a fresh oil change are recommended at fitment, and we strongly recommend cleaning the oil feed banjo strainer and inspecting the oil return line before installing any used N20 turbo.
