Cheap BMW 8 Series Seat

The current G15 8 Series ran from 2018 onwards, so a 2019 seat and a 2022 seat are from the same generation and should be compatible in principle, but confirm with the breaker that the trim level and side match your car before ordering.

No — the E31 8 Series (1989–1999) and the G15 8 Series (2018–present) are entirely different generations with no shared interior architecture, so seats are not interchangeable between them.

Yes, trim level matters — the 8 Series is offered in grades including M Sport and individual higher-spec options, and seat style, upholstery, and heating or massage functions can differ between them; confirm the trim of the donor car matches yours, and be aware there may be cosmetic differences even within the same generation if the spec levels differ.

Engine makes no difference for seat fitment — what matters is the generation (G15), trim level, and that the seat is nearside (left-hand, driver's side in a UK right-hand-drive car), so don't rule out a part just because the donor car had a different engine.

Side-impact airbags built into seat squabs are safety-critical items; they are single-use and must never be refitted if previously deployed, and professional fitting is strongly recommended to ensure correct connection to your car's SRS system. You should also confirm with the breaker that the airbag module is compatible with your specific SRS setup against your registration, as this is not something that can be guaranteed universally.

The G15 8 Series received a facelift during its production run, and while the generation name is the same, interior trim and seat fixings can change at a facelift point — name the exact year of both your car and the donor car to the breaker, and ask them to confirm compatibility across that boundary before purchasing.
