Mercedes-Benz SLK Parking Sensor Replacement Parts

Yes, parking sensors were available on the SLK across its generations, typically as an optional extra or fitted as standard on higher-specification variants — so not every SLK will have them. If you are sourcing a used sensor, it is worth checking whether your car was originally built with the system by looking for the sensor holes in the bumper or checking your build sheet. A breaker can also confirm whether the part they have came from a sensor-equipped car.

The R170 and R171 are distinct generations with different rear bumper designs, so parking sensors from one will not directly swap to the other — the physical sensor diameter may be similar, but the bumper housing and wiring connector are unlikely to match. The R171 was facelifted in 2008, though the bumper-mounted sensor setup remained broadly consistent across that generation. Confirm the exact part and connector type with the breaker against your registration before buying.

This is the key boundary to watch: the R171 facelift in 2008 brought styling updates that may have affected bumper design and sensor fitment points, so parts are not guaranteed to interchange across that divide. The sensor body size is often consistent within a generation, but connector and control-module compatibility can differ. Route this question to the breaker and give them your registration so they can check the exact part number.

Within the R172 generation (which ran from 2011 and received a mild refresh around 2015–2016), sensors from cars of the same bumper configuration are generally more likely to be compatible, but the late refresh may have introduced changes to bumper design or sensor specification. Always confirm with the breaker using your registration to make sure the sensor count, connector type, and control module match your car.

Trim level and engine choice do not fundamentally determine the parking sensor hardware — what matters is which bumper the car has and whether the sensor system was fitted, either as standard or as a factory option. An AMG Line car may have a different bumper styling to a standard car, which could affect the sensor aperture or finish, so it is worth checking cosmetic differences even if the underlying sensor specification is the same. Confirm with the breaker that the sensor came from a car with the same bumper style as yours.

SLK models with parking sensors are typically fitted with rear sensors only, usually four, though some configurations may include front sensors depending on the options specified on that individual car. You do not necessarily need to replace all sensors at once, but if one is faulty it is worth checking the others for wear, and the replacement sensor should match the specification and colour of those already fitted. Ask the breaker whether they can supply individual sensors or a full set, and confirm the sensor matches your bumper colour or can be painted.
