Genuine Renault Rear ABS Speed Sensor - Megane 4 RS

Why a malfunctioning rear ABS sensor affects your driving dynamics

On a high-performance hot hatch like the Renault Megane 4 RS, the wheel speed sensor does far more than just calculate speedometer readings. It continuously transmits crucial data to dynamic control units. Driving with a defective or fouled rear ABS sensor exposes your vehicle to significant performance and safety issues:

• Electronic assistance deactivation: Dashboard warning lights (ABS, ESP, Hill Start) trigger safety limp modes in assistance systems, depriving the driver of fine-tuned traction management.
• Loss of 4Control steering: On chassis equipped with four-wheel steering, a missing speed signal from the rear axle disrupts or disables rear-wheel dynamic steering, severely reducing cornering agility.
• Restricted drive modes: Inability to select performance modes (RS / Race modes) or loss of telemetry data displays.
• Impaired braking stability: Risk of unwanted rear wheel lockup under hard braking or on slippery surfaces, compromising rear axle stability.
• Roadworthiness test failure: An illuminated ABS or ESP warning light on the dashboard results in an automatic inspection failure.

The Guarantee of Genuine RENAULT OEM Quality
