Cheap BMW i4 Ignition Switch

No – the BMW i4 is a fully electric vehicle and has never been fitted with a traditional ignition switch on any variant. Instead of a key-operated barrel, the i4 uses a push-button start system combined with a BMW key fob or digital key; there is no ignition switch assembly to source from a breaker. If you are hearing a fault related to starting, you may be looking for the start/stop button, the EWS (electronic immobiliser module), or a key fob – a BMW-specialist breaker can advise which component is actually causing your issue.

The start/stop button is the closest equivalent on the i4 to a traditional ignition switch, but they are entirely different components – the i4 was never built with an ignition barrel or switch at all. The push-button itself is what you would be sourcing from a breaker, and it is worth confirming your exact model year and trim with the breaker so they can match the correct part to your car's specification. Searching for an 'ignition switch' will not return a usable result for the i4.

No – because the i4 was never designed around an ignition switch, there is no mounting point, wiring loom connection, or compatible housing for one in the vehicle. The i4's starting system is fully electronic and managed through its EV platform, which is fundamentally different from combustion-engined BMW models. If you need a starting-system component, speak to a breaker and describe the specific symptom you are experiencing so they can identify the correct part.

Depending on your fault, the parts most likely to be relevant are the start/stop button assembly, the key fob or comfort access module, or the EWS immobiliser unit. The i4 (G26 platform, launched 2021) is a single-generation model at the time of writing, so confirm your exact build year and trim – whether eDrive35, eDrive40, M50, or M60 – with the breaker to ensure any electronic component is correctly matched. A breaker who specialises in EVs or modern BMWs will be best placed to diagnose which part you actually need.

Trim level – such as eDrive35, eDrive40, M50, or M60 – does not fundamentally change the start/stop button specification, as this is a platform-level component across the i4 range. However, cosmetic differences in finish (for example, a higher-spec interior may have a differently styled surround or ambient lighting integration) may mean the visual appearance varies between trims, so confirm the part's appearance against your own car before buying. Always verify the part number with the breaker against your registration to be certain.
