Cheap Mercedes-Benz EQC Oxygen Sensor

No — the EQC is a fully battery-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 gas composition and control fuelling. If your dashboard is showing a fault that a garage has described using lambda or O2 sensor terminology, this may be a misdiagnosis or confusion with another vehicle — worth going back to the garage for clarification. You may want to search instead for the specific sensor or module relevant to the EQC's electric drivetrain, such as a temperature sensor or high-voltage system component.

It is almost certainly incorrect — the EQC is a pure electric vehicle launched in the UK in 2019 and has no combustion engine, exhaust, or lambda sensors of any kind. An oxygen sensor quote for an EQC suggests either the wrong vehicle has been looked up or there has been a miscommunication about the fault. We'd recommend double-checking the registration and the fault code with your garage before ordering any part. If you drive a different Mercedes model such as a GLC or C-Class, those do have oxygen sensors and we can help you find the right one.

Because the EQC is fully electric, any fault code referencing an oxygen or lambda sensor is likely being misread or has been generated by diagnostic equipment not fully calibrated for electric vehicles. There is no exhaust or emissions-control hardware on the EQC for such a sensor to connect to. A Mercedes-specialist garage or franchised dealer with EQC-specific diagnostic tools is the best port of call to correctly interpret the fault. The underlying issue may relate to a battery management, thermal, or drivetrain sensor that has nothing to do with exhaust emissions.

Because the EQC is a battery-electric vehicle, the sensors available from breakers will relate to its electric drivetrain and thermal management systems rather than anything exhaust-related. These can include components such as temperature sensors, wheel speed sensors, and various modules associated with the high-voltage battery and electric motors. When contacting a breaker, always provide your full registration so they can confirm exact compatibility, as sensor specifications can vary. Bear in mind that high-voltage EQC components may carry additional safety and handling considerations that a good breaker will be aware of.
