ABS System Repair | ABS, ASR & ESP®

.

The service explains how the main car safety systems work and ensures they are tested and repaired correctly by a Bosch Car Service expert.

• ABS (Anti-lock Braking System): Prevents wheel lock-up during hard braking so the vehicle remains steerable. During service, the ABS control module, sensors and hydraulic unit are tested and repaired if needed.
• ASR (Traction Control): Regulates wheel slip when accelerating to maintain traction and stability. The service identifies faults in the ASR module and restores correct operation.
• ESP® (Electronic Stability Program): Helps keep the vehicle under control if it begins to skid, especially during sudden manoeuvres or sharp turns. The ESP system and its sensors are checked and calibrated.

With Bosch diagnostic technology and OEM-quality parts, Bosch Car Service in the UAE provides reliable ABS system repair, ESP module repair and complete safety system diagnostics to keep your vehicle stable and safe on the road.

During the inspection, the workshop performs full safety system diagnostics to test the ABS control module, ESP system, traction sensors and hydraulic unit. Fault codes are read, components are measured under load and the calibration of the stability functions is verified. If required, a professional ABS system repair or ESP module repair is carried out using OEM-grade Bosch parts.

A defective control unit often shows through dashboard warning lights, such as the ABS warning light or ESP light on, as well as irregular braking behaviour or traction issues. If these signs appear, it can indicate a failing module and the vehicle’s safety functions may no longer operate correctly. In this case, professional ABS system repair and diagnostics are required to restore full safety and stability.

These systems should be inspected as soon as a warning light appears on the dashboard or irregular braking/traction behaviour is noticed. As a guideline, they should also be checked every two years or during regular vehicle maintenance.

Early diagnostics help detect faults in the control unit or sensors before they become a safety risk — and allow timely ABS system repair if needed.

ESP (Electronic Stability Program) helps keep the vehicle stable during sudden manoeuvres or loss of traction. When the ESP warning light appears, it usually indicates a fault in the control unit or one of the sensors.

A professional diagnostic check is recommended to ensure the stability system is working correctly and to prevent further safety issues. If the fault persists, an ABS system repair or ESP module repair may be required.

The repair time depends on which system is affected and how severe the fault is. In most cases, an ABS system repair or ESP module repair can be completed within a few hours or the same day. Simple sensor-related issues are usually resolved quickly, while hydraulic or control unit repairs may take longer.

As a guideline:

• ABS system: a few hours to one day
• ESP / stability control: half a day to one full day
• ASR / traction control: typically a few hours
• Hydraulic brake unit: around one full day

The duration can be influenced by several factors, including:

• Type of fault (sensor vs. ABS control unit vs. hydraulic block)
• Vehicle brand and model (premium vehicles often require more steps)
• Whether recalibration is required after the repair
• Diagnostic time if multiple warning lights are active

Bosch Car Service uses advanced diagnostics and OEM-grade parts to complete the repair as efficiently as possible while maintaining full safety functionality.
