Buying a used BMW i4 lambda sensor: what matters
Fitment on a used lambda sensor varies by vehicle, so a bit of detail goes a long way. Our request form covers what breakers need to know, so every quote you get back is for the correct part:

Fitment questions
Does the BMW i4 have a lambda sensor?
No — the BMW i4 is a fully electric vehicle and has no internal combustion engine, exhaust system, or emissions control equipment of any kind. Lambda sensors (oxygen sensors) are part of a petrol or diesel exhaust system and monitor exhaust gases to control fuelling, so they simply do not exist on the i4. If you are looking for a lambda sensor, it is worth double-checking that your vehicle is the i4 and not the 4 Series (G22/G26), which shares a platform and some visual similarities but uses conventional combustion engines. A UK breaker will be able to help you source the correct part once you confirm your actual model.
I searched for a BMW i4 lambda sensor and got results — are these listings correct?
Almost certainly not matched to your vehicle — the BMW i4 is fully electric and has never been fitted with a lambda sensor in any variant or trim level. Listings appearing under i4 searches are likely the result of catalogue errors or sellers using broad search terms that overlap with the combustion-engined 4 Series range. Always quote your full registration to a breaker so they can confirm the exact model before purchasing any part.
Could I need a lambda sensor for my BMW i4 eDrive40 or M50?
No — both the eDrive40 and M50 are fully electric variants of the i4; neither has an exhaust, catalytic converter, or lambda sensor. The lambda sensor is purely an exhaust-system component used on petrol and diesel engines to manage fuel mixture and emissions compliance. If your i4 has triggered a fault code relating to emissions or sensors, the fault will be something entirely different — an EV-specific sensor or control module — and a BMW specialist or dealer would be the right starting point for diagnosis.
What part might I actually be looking for on my BMW i4 instead of a lambda sensor?
That depends entirely on what fault or symptom you are trying to address; common electrical or sensor-related issues on the i4 are more likely to involve high-voltage battery management sensors, temperature sensors, or inverter components rather than anything exhaust-related. If you have a specific fault code, quoting it to a breaker or BMW specialist will help identify the correct component. It is also worth confirming via your registration that your car is genuinely the i4 and not the conventionally engined 4 Series, as the two are sometimes confused.
