ATE ABS Wheel Speed Sensor for Mercedes-Benz CLS-Class and E-Class (2010–2018)

The ATE 360663 ABS wheel speed sensor measures the rotating speed of one wheel and reports it to the anti-lock brake system on the Mercedes-Benz CLS-Class and E-Class models shown in the fitment table. It reads a reluctor wheel or magnet located near the wheel hub, and the same signal gives the traction control and stability control systems their reference points. Every car with ABS uses four of these sensors, one at each corner. ATE builds this sensor in Germany, and it cross-references to Mercedes-Benz numbers A2129053303 and A2129050701.

ATE parts sold by PMB carry a 24-month or 24,000-mile warranty.

When a speed sensor fails, the ABS stops working, and traction and stability control usually drop out with it. The typical signs are an ABS warning light on the instrument cluster, traction and stability control that no longer respond, and anti-lock braking that does not engage. A worn wheel bearing can also set an ABS fault, because on some designs the reluctor is part of the bearing, the hub, or the axle. For that reason, a full diagnosis of the ABS system and the parts around it should come before replacing the sensor. ATE traces its history to 1906, when Alfred Teves founded the company, and today it belongs to AUMOVIO, the former automotive division of Continental AG.

Common Questions

Will a failed sensor affect traction control?
Yes. A failed wheel speed sensor shuts down the ABS and will likely disable traction and stability control as well, since both rely on wheel speed readings.

Could the wheel bearing be the real problem?
It can be. A bad wheel bearing can cause an ABS fault, so check the whole ABS system and its related parts before ordering a sensor.

Which Mercedes-Benz numbers does this sensor match?
It cross-references to A2129053303 and A2129050701, which is a handy check against the number on your old sensor.
