BMW i3 Oxygen Sensor Replacement Parts

No — the BMW i3 is a fully electric vehicle (BEV) and the range-extender (REX) variant uses a tiny two-cylinder petrol engine primarily to generate electricity, not to drive the wheels in a conventional sense. Neither version uses a traditional exhaust oxygen (lambda) sensor in the way a petrol or diesel car does, because the i3 BEV has no combustion engine at all, and the REX's simplified two-cylinder unit does not use a conventional closed-loop lambda feedback system with a standard fitment oxygen sensor. If you think you need an oxygen sensor for your i3, it's worth double-checking the part you actually need — you may be looking for something else entirely, or you may have the wrong vehicle listed.

It's very unlikely. The i3 REX (range extender) uses a small two-cylinder engine that is not managed in the same way as a conventional petrol car, and a traditional upstream or downstream oxygen sensor is not a standard fitment on it. It's possible a supplier has misidentified the part or applied a generic search result — we'd strongly recommend checking with the breaker directly, quoting your full registration, to confirm what you actually need. There may be a different emissions-related component on the REX that has been confused with a lambda sensor.

The i3 BEV has no exhaust system at all, so neither a catalytic converter nor a DPF applies. The i3 REX does have a small exhaust system to handle emissions from its range-extender engine, and whether it carries a catalytic converter or related component is something you should confirm with the breaker against your exact registration, as interchange specifics for REX exhaust components are strong confirm-with-breaker territory. Do not assume a part from another BMW model will fit.

Trim level makes no difference here, but in this case that's because no variant of the BMW i3 is fitted with a conventional oxygen sensor — trim, colour, and interior specification are all irrelevant. The only variant distinction that matters for exhaust-related parts is BEV (pure electric) versus REX (range extender), since only the REX has any combustion engine or exhaust at all. If you are sourcing any exhaust-related part for a REX, always quote your full registration to the breaker rather than relying on trim name alone.

This question doesn't apply to the i3, because no version of the car — early or post-facelift — uses a conventional oxygen sensor. The i3 was launched in 2013 and received a notable update around 2017 (introducing the 94Ah battery and later the 120Ah), but these differences relate to battery and electric drivetrain technology, not to exhaust lambda sensing. If you are sourcing any exhaust component for a REX variant specifically, confirm with the breaker using your registration, as REX exhaust parts across these production periods may differ.
