Mercedes-Benz GLC Parking Sensor Replacement Parts

The Mercedes-Benz GLC runs in two clear generations: the X253, built from 2015 to 2022 (with a facelift around 2019), and the X254, which launched from 2023 onwards. A sensor from a pre-facelift X253 (2015–2019) and a post-facelift X253 (2019–2022) may share the same physical fitment, but connector pinouts and coding can differ across that 2019 facelift boundary, so confirm with the breaker that the donor car's registration matches your side of that line. Never assume a part will plug straight in without checking.

Trim level — whether SE, Sport, AMG Line, or any other — does not change which parking sensor is fitted to the bumper; the sensor itself is the same part. What you may notice is a colour difference if the donor bumper sensor was painted to match a specific finish, but the sensor unit underneath is interchangeable across trims within the same generation. Just confirm the sensor count matches your car (some trims added rear sensors only, others had front and rear as standard or optional).

The GLC X253 typically came with four rear parking sensors as standard across most trim levels, with front sensors available as part of an optional parking package on higher specifications. The X254 generation from 2023 broadened standard fitment further, so the number of sensors on a donor car can vary. When buying used, confirm with the breaker how many sensors the donor vehicle had so you are sourcing a matching set.

No — the X254 (2023 onwards) and X253 (2015–2022) are different generations with different bumper designs, wiring harnesses, and PDC control units, so sensors from one will not cross over to the other. Always source your sensor from a donor car within the same X253 generation as your vehicle. Confirm the exact donor registration with the breaker to be certain.

Engine type has no bearing on parking sensor fitment — the sensors sit in the bumper and are entirely independent of the drivetrain. A sensor from a diesel 220d donor will physically and electrically match the same position on a petrol 300 of the same generation. Focus instead on generation (X253 or X254) and which facelift phase the donor car belongs to.

In most cases you can replace a single faulty sensor, provided you match the generation, the pre- or post-facelift phase, and the colour code if the sensors in your bumper are painted. Front and rear sensors on the GLC are not always interchangeable with each other, so make sure you specify to the breaker whether you need a front (NS or OS) or rear sensor. Confirm the part number from your existing sensor with the breaker where possible to get the closest match.
