BMW i4 Timing Chain Replacement Parts

No – the BMW i4 is a fully electric vehicle and has no internal combustion engine, so it has no timing chain, cambelt, or any other valve-train drive component whatsoever. The drivetrain consists entirely of electric motors, a single-speed reduction gearbox, and associated power electronics. If you are searching for a timing chain for this vehicle, it is possible you have the wrong model noted down – double-check your V5 or run a VIN check to confirm the exact vehicle.

It is almost certainly a mistake or a misunderstanding, as the i4 is a pure electric car with no combustion engine and therefore no timing chain exists on any variant of this model. A breaker quoting you one may have confused the i4 with a petrol or diesel BMW of a similar name, such as the 4 Series Gran Coupé on which the i4 body is based, which does have combustion engine variants with timing chains. Go back to the breaker with your exact registration or VIN to make sure you are both looking at the correct vehicle.

No trim level of the BMW i4 has a timing chain, because every single variant – including the eDrive35, eDrive40, xDrive40, and the high-performance M50 – is fully electric with no combustion engine. Trim level makes no difference here because the fundamental drivetrain architecture is the same across the range. If you need a mechanical wear part for an i4, the components to consider would be things like the single-speed reduction drive unit rather than anything from a conventional engine.

Because the i4 uses electric motors rather than a combustion engine, there is no timing chain, timing belt, or camshaft to drive. The equivalent high-wear or replaceable mechanical components on an electric drivetrain are parts such as the electric motor assembly, the reduction gearbox, drive shafts, or wheel bearings. Speak to a breaker who specialises in EV or BMW electric vehicles and give them your full VIN so they can identify the correct drive unit variant for your specific car.

This question does not apply to the BMW i4 because no timing chain was ever fitted to this model in any production year – the i4 launched in 2021 as a fully electric vehicle and has remained so, with no combustion engine variant at any point in its production run. If you are researching a different BMW model that shares the i4's body style but has a petrol engine, that would be the combustion-engined 4 Series Gran Coupé, and a breaker would need your engine code and registration to confirm timing chain compatibility across model years for that car.
