Cheap Mercedes-Benz EQE Lambda Sensor

No — the EQE is a fully electric vehicle with no internal combustion engine, no exhaust system, and no catalytic converter, so it has never been fitted with a lambda sensor at any point in its production. Lambda sensors exist solely to measure oxygen in exhaust gases and feed data back to a petrol or diesel engine management system, neither of which the EQE has. If your EQE has a fault code or warning light, it will relate to a different system entirely — your Mercedes dealer or an EV-specialist independent is the right port of call.

Almost certainly yes — no variant of the EQE, whether the EQE 300, EQE 350, EQE 43 AMG, or EQE 53 AMG 4MATIC+, has ever been fitted with a lambda sensor, because every version is battery-electric with no combustion engine or exhaust. It's possible the quote was generated in error, or that the vehicle's registration was confused with a combustion-engine Mercedes such as the E-Class. Go back to the dismantler with your registration and clarify exactly which vehicle and fault you're dealing with.

No — oxygen sensors, NOx sensors, and lambda sensors all serve the same fundamental purpose of monitoring exhaust gases, and none of these apply to the EQE because it produces no exhaust gases whatsoever. Sensors you might legitimately need on an EQE relate to the high-voltage battery system, thermal management, or electric drivetrain rather than anything exhaust-related. If a diagnostic tool has flagged a sensor fault, have the specific fault code interpreted by someone familiar with electric vehicles before ordering any parts.

No — trim level makes no difference here, because the absence of a lambda sensor is not a trim-level characteristic but a fundamental consequence of the EQE being a fully electric vehicle. Whether you have a standard EQE 300 or a top-specification EQE 53 AMG 4MATIC+, none of them have an exhaust system of any kind. If you were hoping trim level might explain a parts discrepancy, the explanation is simply that this part category does not exist on this model at all.

The EQE has no exhaust system — no downpipe, no catalytic converter, no DPF, no lambda sensor, and no tailpipe — so none of those parts exist for this vehicle. If you have a genuine mechanical or fault-related issue, the relevant components are more likely to be within the battery thermal management system, the electric motor assembly, or associated control units. Speak to a dismantler who specifies in electric or Mercedes-Benz vehicles and give them your exact registration so they can identify the correct part category for your fault.
