BMW 6 Series Crankshaft Replacement Parts

The BMW 6 Series spanned two main generations: the E63/E64 (2003–2010) and the F12/F13/F06 (2011–2018), so a 2010 and a 2014 car sit in completely different generations with different engine families and different crankshafts. The critical detail is the engine code, not the model year — even within a generation, different engine variants use different cranks. Confirm both engine codes with a VIN check or your V5, and give them to the breaker before ordering.

The 640d and 630d are both diesel variants of the F12/F13/F06 6 Series but use different engine tuning states, and whether their crankshafts interchange depends on the exact engine code rather than the badge. Some BMW diesel variants within the same family do share rotating assembly components, but you should not assume this is the case here. Give the breaker both engine codes — found on the V5 or a VIN check — and let them confirm compatibility before you commit to buying.

Body style makes no difference to crankshaft fitment — the crank is entirely determined by the engine fitted to the car, not whether it is a Gran Coupé (F06), Coupé (F13), or Convertible (F12). All three body styles were available across the F12/F13/F06 generation from 2011 to 2018, and if two cars share the same engine code they will share the same crankshaft. Focus on matching the engine code exactly, and ignore body style entirely when sourcing this part.

Trim level — for example SE, Sport, M Sport, or M6 — has no bearing on crankshaft fitment whatsoever. What matters is the engine code, fuel type (petrol or diesel), and the generation of the car. The one exception worth noting is the full M6, which uses a dedicated high-performance engine with its own crankshaft specification entirely different from standard 6 Series units, so always confirm the engine code via your V5 or a VIN check.

The E63/E64 generation ran from 2003 to 2010 and received a facelift in 2007, but whether the facelift brought any internal engine changes that affect crankshaft interchangeability depends on the specific engine code involved. In many cases the same engine codes carried across the facelift with no crankshaft change, but ancillary or mounting changes within a production run are something you should confirm with the breaker against your registration rather than assume. Supply both registrations or engine codes to the breaker and let them verify before purchasing.

The single most useful piece of information is your engine code, which you can find on your V5 logbook or by running a VIN check — this tells the breaker exactly which rotating assembly your engine requires. You should also confirm your fuel type (petrol or diesel) and the model year, as the E63/E64 generation (2003–2010) and the F12/F13/F06 generation (2011–2018) use entirely different engines. Body style, colour, and trim level can be ignored for this part — engine code is what drives fitment.
