BMW 8 Series Sump Replacement Parts

The 8 Series in its current generation runs from 2018 onwards, so it is worth knowing that even within that generation BMW made running changes to engines, and the engine code is the detail that matters most here — not the model year alone. If your registration straddles a mid-cycle update, the sump mounting face or oil pick-up position may differ, so always confirm the exact part against your registration with the breaker. Supply your engine code from your V5 or a VIN check and the breaker can match it precisely.

The engine code matters above everything else for a sump — two 8 Series cars built in the same year can have completely different bottom-end architecture depending on whether one is a 630i, 840i, M850i, or M8, because those badges represent entirely different engine families. The year narrows things down but it cannot replace the engine code, which you will find on your V5 logbook or through a VIN check. Give the breaker both the engine code and your registration and they can confirm the correct part straight away.

Yes, fuel type is a fundamental fitment factor — a petrol sump and a diesel sump are not interchangeable even if the cars look identical from the outside. The 8 Series was available with both petrol and diesel engines in the UK, and each engine family has its own sump design, oil capacity, and mounting arrangement. Always state your fuel type and engine code when requesting a quote from a breaker.

No, these are different engines entirely — the 840d is a diesel and the 840i is a petrol straight-six, so their sumps are not interchangeable despite sharing a badge series and body. Mechanical parts follow the engine, not the badge, and the sump is no exception. Always quote your engine code to the breaker to make sure you are matched to the correct unit.

M Sport is a trim and styling package, not a different mechanical specification, so it does not alter the engine or the sump required — what matters is the engine code, which is the same regardless of whether the car is badged M Sport or not. You may find that a car described as a breaker has different exterior trim or interior details, but those cosmetic differences are irrelevant to sump fitment. Confirm the engine code matches yours and the breaker can advise on compatibility.

The sump is determined by the engine, not the body style, so if two cars share the same engine code the sump is likely to be the same regardless of whether the donor car was a coupe, Gran Coupe, or Convertible. That said, ancillary mounting details can occasionally differ between body variants, so confirm the match against your specific registration with the breaker rather than assuming it is a straight swap. Supplying your engine code gives the breaker everything they need to check this properly.
