Fitment questions
Will an alternator from a 2020 BMW 8 Series fit my 2019 model?
The current G-generation 8 Series launched in 2018, so a 2019 and a 2020 car sit within the same generation and share the same engine families — if the engine codes match, alternator fitment is very likely. Engine code is what matters here, not the model year, so check your V5 or run a VIN check to confirm yours before approaching a breaker. Always confirm the exact part number with the breaker against your registration to be certain.
Does an alternator from a G15 Coupe fit a G14 Convertible or G16 Gran Coupe?
The G14 Convertible, G15 Coupe, and G16 Gran Coupe are all part of the same G-generation 8 Series family launched from 2018, and body style does not affect alternator fitment — the alternator follows the engine, not the roofline. Provided the engine codes match across those body styles, the unit should be the same, but confirm with the breaker against your specific registration to be sure.
I have an 840d — will an alternator from an 840i fit?
The 840d is a diesel and the 840i is a petrol, and fuel type directly affects which alternator is fitted, so these are not interchangeable even though the badge numbers look similar. Always match on engine code rather than badge name, and quote your exact engine code to the breaker so they can pull the right unit.
Does the M850i need a different alternator compared to a standard 840i?
The M850i uses a different engine (the S63 twin-turbo V8) compared to the 840i (the B58 straight-six), so they require different alternators — trim level itself is not what changes fitment, but in this case the trim reflects a genuinely different engine. Give the breaker your engine code rather than just the model name, and they can match the correct unit to your car.
Will a pre-facelift 8 Series alternator fit a post-facelift car — for example, a 2021 versus a 2023?
The G-generation 8 Series received a facelift for the 2022 model year, so a 2021 car is pre-facelift and a 2023 is post-facelift. The engine codes within each variant largely carried over the facelift, so if the codes match the alternator may well interchange, but ancillary and mounting changes can occur mid-production — confirm with the breaker against both registrations rather than assuming.
Does it matter whether my 8 Series is an automatic or manual when buying a used alternator?
Gearbox type can influence ancillary components in some BMW applications, so it is worth mentioning to the breaker, but the alternator is primarily determined by engine code and fuel type rather than gearbox choice. Quote your full engine code and registration to the breaker so they can cross-reference and confirm the correct unit for your car.
