**Premium Used ESP Control Unit for Citroën DS5LS – Fully Functional & Original OEM Part**

Ensure the safety and performance of your Citroën DS5LS with this high-quality, original equipment manufacturer (OEM) ESP Control Unit. Sourced directly from a donor vehicle, this is a genuine used part, offering a reliable and cost-effective solution to restore your vehicle’s vital Electronic Stability Program (ESP) and Anti-Skid systems.

This compact but crucial module acts as the brain for your car’s stability control. It continuously processes data from various sensors, including the integrated yaw rate sensor (gyroscope), which monitors the vehicle’s rotation and tilt. By working in harmony with the wheel speed sensors, it can detect loss of traction or the beginning of a skid. In such critical moments, it automatically intervenes by selectively applying brakes to individual wheels and can adjust engine power to help correct your vehicle’s path and maintain stability, especially on slippery roads or during abrupt maneuvers.

**Extremely Important Installation Note:**

**Please be advised that this part requires a specialized calibration procedure after installation.** Simply plugging in the unit is not sufficient. To function correctly and extinguish the ESP/ABS warning lights on your dashboard, a professional **ESP System Calibration/Initialization** must be performed using specialized diagnostic software. This process is typically done by a professional mechanic or a workshop with the appropriate diagnostic tool. We strongly recommend arranging for this service prior to or immediately after installation to ensure the system operates safely and effectively.
