BMW 4 Series Turbo Replacement Parts

The F32-generation 4 Series ran from 2013 to 2020, with a facelift in 2017, so a 2014 and a 2016 car are both pre-facelift and broadly the same generation. Fitment depends primarily on the engine code rather than the year, so if both cars share the same engine code — found on your V5 or via a VIN check — compatibility is much more likely. Confirm with the breaker against your registration before purchasing, as ancillary mounting details can vary within that window.

The F32 4 Series facelift arrived in 2017, and while the underlying engine codes often carried across that boundary, whether a specific turbo unit interchanges between a pre-2017 and post-2017 car is something you should confirm with the breaker against both registrations. Supply your engine code — printed on your V5 or available from a VIN check — as that is the most useful detail for the breaker to match. Do not assume year-to-year compatibility across the 2017 facelift without that check.

Yes — the 420d and 430d use different diesel engines with different outputs, and the turbos are matched to those specific engine codes rather than the badge on the boot lid. Always quote your engine code to the breaker rather than just the model number, as two cars wearing different badges will need different turbos. A VIN check or your V5 logbook will confirm your exact engine code.

For a mechanical part like a turbo, trim level — whether that is SE, Sport, or M Sport — makes no difference to fitment; the turbo follows the engine code, not the trim badge. You may find that an M Sport car from a breaker has different body panels or interior parts, but the turbo itself will be the same as on an SE car running the same engine code. Confirm your engine code with the breaker to make sure the unit is the right match.

No — the 428i and 420i are different petrol engines with different engine codes, and the turbos are specific to those codes, not interchangeable across the range simply because both are petrol. Quote your exact engine code to the breaker, as this is the single most reliable way to ensure you are quoted the correct unit. Using the wrong engine code as a reference is one of the most common causes of buying an incompatible turbo from a dismantler.

Yes, the F32-generation 4 Series ran through to 2020, so a 2019 car is still within that generation — the G22 successor did not arrive until 2020. Turbo fitment on your 2019 car is still driven by the engine code above all else, so supply that code to the breaker rather than just the year. Confirm with the breaker against your registration to rule out any late-production ancillary or mounting variations.
