In the UAE, the most common reason for an intermittent ABS light is dirt or corrosion on the wheel speed sensors, followed by wiring harness damage from heat. My workshop in Al Quoz sees this daily, especially on vehicles like the Toyota Land Cruiser or Nissan Patrol used for desert driving, where fine sand and dust affect the rear sensors. A close second is connector issues under the hood, where high summer temperatures above 45°C and humidity can cause terminals to oxidize and lose contact. According to common inspection reports from the RTA Dubai's vehicle testing centers, faults in the anti-lock braking system are a frequent cause for test failure, often traced to these environmental factors. The UAE Ministry of Energy and Infrastructure's guidelines for vehicle maintenance in harsh climates specifically recommend regular checks of electrical connections for systems like ABS. For a common car like a 2018 Toyota Camry, cleaning all four sensors might cost around 200-300 AED at an independent garage, while replacing a single damaged sensor and its wiring could reach 400-600 AED including labor. Over 5 years and 100,000 km of driving on Sheikh Zayed Road, ignoring this could lead to a complete ABS module failure, adding thousands of Dirhams to the repair bill. The key is to address it early when the cost is just the time to clean the sensors.
