Mercedes-Benz GLC Oxygen Sensor Replacement Parts

Yes, but only on petrol-engined GLC variants — the 200, 250, and AMG 43/63 petrol models all use lambda (oxygen) sensors as part of their exhaust management system. Diesel GLC variants (the 220d, 250d, and 300d) do not use oxygen sensors in the same way; diesels rely on NOx sensors and other emissions hardware instead, so if you have a diesel GLC you are almost certainly looking for a different part. If you are unsure which engine you have, check your V5C or the plate under the bonnet for the engine code before ordering.

The GLC X253 ran from 2015 to 2022 as a single generation, with a facelift arriving in 2019 that updated styling and infotainment but retained the same core engine family. Fitment of the oxygen sensor is driven by the engine code and emissions standard (Euro 6 applies across the X253 petrol range), so a sensor from the same engine code on either side of the 2019 facelift may well interchange — but you should confirm the exact engine code match with the breaker against your registration, as sensor position and connector type can vary. Never assume a sensor will fit purely because the generation name is the same.

No — trim level does not affect which oxygen sensor your GLC needs. AMG Line, Sport, and SE are specification packages covering interior, wheels, and cosmetic items; they do not alter the engine or exhaust system. What matters is your engine code and fuel type, so focus on matching those rather than the trim badge.

The 250 and 200 petrol engines in the X253 GLC are different units — the M274 2.0-litre turbo used in the 250 and the later M264 2.0-litre used in the 200 are not the same engine family throughout the production run, so the sensors are not guaranteed to interchange. Always match by engine code rather than engine displacement or power output, and confirm with the breaker using your exact registration to be sure.

The GLC Coupe (C253, 2016–2023) shares its petrol engine codes with the standard GLC (X253), so sensors from the same engine code in the same emissions era are likely to be the same part. However, it is always worth confirming with the breaker that the engine code and model year match exactly, as minor running changes can affect connector types or sensor calibration. The body style difference between the SUV and Coupe does not in itself affect the oxygen sensor specification.

The M274 engine was used across several Mercedes-Benz models including the C-Class and GLC, and in principle the oxygen sensor specification follows the engine rather than the body. That said, exact sensor position, harness length, and connector can differ between model applications, and emissions compliance must match — confirm with the breaker that the donor part number and engine code match your GLC's registration before buying.
