Cheap Mercedes-Benz EQE Oxygen Sensor

No — the EQE is a fully electric vehicle with no internal combustion engine, so it has no exhaust system, no catalytic converter, and no oxygen sensor whatsoever. Oxygen sensors are only fitted to petrol and diesel engines to measure exhaust gases and manage fuelling, none of which applies here. If your EQE has a fault code or warning light, the sensor involved is almost certainly something else — perhaps a temperature sensor, a high-voltage battery sensor, or a position sensor. A Mercedes specialist or dealer with the correct EV diagnostic equipment is the right starting point.

It is almost certainly a mistake or a miscommunication, as the EQE has no combustion engine and therefore no oxygen sensor. The term 'sensor' covers many components on an electric vehicle, and it's possible a workshop or parts adviser has used the wrong terminology when describing what's needed. Check the exact fault code or job description carefully, and clarify with the repairer what specific sensor is actually required. Once you know the correct part name, a breaker specialising in EV or Mercedes parts will be better placed to help.

It's possible the part has been described loosely or confused with a sensor from a petrol or diesel Mercedes sharing a similar name. The EQE does carry various sensors — including those related to the thermal management system, inverter, or drive unit — but none of these are oxygen sensors in the exhaust sense. If you have a part number from a diagnostic report, share that directly with a breaker so they can identify it correctly rather than searching under the wrong description. Fitting the wrong sensor could cause further faults, so getting the correct identification first is important.

Breakers dismantling EQE vehicles may be able to supply components such as speed sensors, temperature sensors, radar or camera sensors, and other electronic modules, though availability of used EV parts is still limited compared to combustion vehicles. The EQE was introduced in 2022 as Mercedes-Benz's dedicated electric executive saloon on the EVA2 platform, so salvage examples are not yet common in the UK. If you know the specific sensor description or part number needed, it's worth contacting a breaker directly to check whether they have a suitable donor vehicle. Always confirm the part number and build-date compatibility with the breaker against your exact registration.
