Land Rover Part Number: LR128703 - Turbine Shut Off Valve Kit
LR128703 is a Turbine Shut Off Valve Kit fitted to the right-hand secondary turbocharger on specified 3.0 V6 diesel engines. The kit contains components that control exhaust flow through the secondary turbo, reducing backflow and aiding staged turbo operation by closing or modulating the turbine inlet when the secondary stage is not required. Correct operation of the valve helps maintain expected turbocharger behaviour and consistent boost characteristics; technicians will replace the kit when the valve fails, sticks or develops leaks that affect turbo response. Follow standard workshop procedures when removing and refitting turbocharger-related assemblies, observing manufacturer guidance for cleanliness and sealing of mating surfaces.
