Genuine Renault Front Left ABS Sensor (Speed Sensor) - Megane 4 RS

The risks of a faulty ABS sensor on your Megane 4 RS

Ignoring a failing wheel speed sensor on a Megane 4 RS is an error that can be costly. Without precise data sent by this front left ABS sensor, your vehicle instantly loses the use of its active safety systems. By not replacing this part, you expose yourself to the loss of ABS and ESP, and also trigger a "limp mode" for the 4Control system (four-wheel steering), making your handling unpredictable and dangerous on both track and road.

Why demand Genuine Renault Sport parts?

The braking system of a hot hatch with over 280 horsepower tolerates no compromise. Unlike cheap aftermarket sensors that often cause communication errors with the ECU, this genuine Renault ABS sensor guarantees perfect impedance and optimal resistance to the high temperatures generated by Brembo calipers. It is the only logical choice to maintain the electronic integrity of your premium vehicle.

Symptoms of a failing wheel speed sensor

Several signs indicate it is time to intervene:

• ABS/ESP warning light illuminated on the dashboard.
• Unstable or stuck speedometer reading.
• Malfunction of the cruise control or emergency braking system.
• Abnormal behavior of the electronic limited-slip differential.
