BMW 120d 320d 520d X3 2.0d Turbo Core

This is a turbo cartridge (CHRA), not a complete turbocharger

A cartridge — also called a CHRA or turbo core — is the centre section of a turbocharger: the shaft, the turbine and compressor wheels, the bearings and the centre housing. It is the part that wears out.

Buy a cartridge when your existing housings and actuator are still in good condition and only the centre has failed. Fitting one means transferring your own housings across and having the assembly balanced and set up correctly — this is workshop work, not a bolt-on replacement.

If you would rather fit a complete, ready-to-go unit, see our complete turbochargers.

Make sure it is the right one. Do not order a cartridge from your engine size alone — the same engine was often fitted with more than one turbocharger. Find the number stamped on the plate on your existing turbo and check it against the part numbers listed on this page. If you are not certain, send us the number and we will confirm it before you pay.
