Cheap BMW 4 Series Starter Motor

The BMW 4 Series F32 generation ran from 2013 to 2020, with a facelift in 2017, and starter motors in this generation are primarily matched by engine code rather than year — so an N20, N47, or B47 engine should take the same unit across much of the run, but ancillary mounting details can change mid-production without a badge change. Name the generation boundary you're crossing and always confirm the specific part number against your registration with the breaker before buying.

The BMW 4 Series G22 (coupé), G23 (convertible), and G26 (Gran Coupé) all share the same G-generation platform from 2020 onwards, and the starter motor fitment is driven by the engine code — so a B47 or B58 engine should pull from the same unit regardless of body style. Body style itself makes no difference to starter motor compatibility, so don't let the coupé versus convertible difference put you off — confirm the engine code with your V5 or a VIN check and verify with the breaker.

All petrol and diesel variants of the BMW 4 Series use a conventional starter motor, so the part genuinely exists across the range — this includes the four-cylinder and six-cylinder engines in both the F32 and G22 generations. The only exception is the BMW 4 Series plug-in hybrid (430e), which uses an integrated starter-generator rather than a conventional starter motor, so if you have the 430e you should tell the breaker explicitly as you need a different type of unit entirely.

No, trim level makes no difference to starter motor fitment on the BMW 4 Series — SE, Sport, M Sport, and xLine are cosmetic and interior packages that don't change the engine hardware. What matters is the engine code (for example N47, B47, N20, B48, B58), which you can find on your V5 logbook or via a VIN check, and whether you have a manual or automatic gearbox, as the starter motor mounting position can differ between the two.

The BMW 4 Series shares its engines and many drivetrain components with the contemporary 3 Series — for example, a B47 diesel in an F32 4 Series is the same engine family used in the F30 3 Series — so cross-model compatibility is genuinely possible. However, ancillary fitment and mounting details can vary between platforms, so match on engine code first and then confirm with the breaker against both registrations before purchasing to avoid a wasted trip.

The starter motor itself is driven by the engine code, not by whether your car is rear-wheel drive or xDrive, so the drivetrain layout doesn't directly change which unit you need. That said, if xDrive variants have any differences in engine bay ancillary positioning, the breaker can check this against your registration — give them both your engine code and your xDrive or RWD spec to be certain.
