Used BMW 6 Series Turbo

The BMW 6 Series (F06/F12/F13) ran from 2011 to 2018, with a facelift in 2015, and whether a turbo crosses that facelift boundary depends heavily on the engine code rather than the year alone — ancillary fittings and mounting points can change mid-production even within the same engine family. Supply your engine code (found on your V5 or via a VIN check) to the breaker so they can match against their donor car rather than relying on year alone. Never assume a pre-facelift turbo drops straight into a post-facelift car without confirming with the breaker against your registration.

Both the 640d and 630d use diesel engines, but they are different states of tune and in some cases different engine codes entirely, so the turbo units are not automatically interchangeable even though both carry the 'N57' family name. The engine code on your V5 is the single most useful detail here — give it to the breaker so they can check the donor car's code is a genuine match. Fuel type and exact engine code matter far more than the badge on the boot lid.

M Sport, SE, and Sport are trim designations on the F12/F13/F06 6 Series and relate to cosmetic and chassis-options differences such as body kits, suspension tuning, and interior finish — they do not determine which turbo is fitted. What determines the turbo is the engine code, so a 640d M Sport and a 640d SE with the same engine code will take the same turbo from a breaker. Be aware you may receive a unit pulled from a car with different cosmetic trim, but that has no bearing on mechanical fitment.

The 635d designation spans across the 2015 facelift, so a 2014 car sits in the pre-facelift generation and a 2016 car in the post-facelift — these can carry the same engine family but ancillary and mounting changes mid-production mean you should confirm with the breaker against your registration rather than assuming a straight swap. Share your engine code from your V5 or a VIN check so the breaker can compare it directly to the donor vehicle's code. The engine code is a far more reliable guide than the model year alone.

The gearbox type itself does not directly determine which turbo is fitted to a BMW 6 Series — the engine code and fuel type are the primary factors. That said, certain engine and gearbox combinations were only offered together on this model, so your gearbox type can help a breaker narrow down which engine codes are plausible in your car. Always confirm against your specific engine code rather than relying on gearbox type alone.

If the engine codes are genuinely identical, the core turbo unit may well be the same part, as BMW used shared engine families across the 5 Series (F10/F11) and 6 Series (F06/F12/F13) of the same era. However, whether ancillary fittings, pipework connections, and mounting brackets are compatible is something you must confirm with the breaker against your registration, as these details can vary even between cars sharing an engine code. Give the breaker both vehicles' engine codes and registrations so they can advise properly before you buy.
