After Accident Repair Services
Accidents can disrupt the performance and safety systems of your Mercedes-Benz. At AT Technicians, we specialise in post-accident diagnostics, repairs, and revalidation to restore your vehicle to optimal condition. Our team uses dealer-level tools to identify hidden faults and ensure all safety systems are functioning as intended. From structural repairs to complex electronic recalibration, our workshop covers every essential service under one roof. We handle crash data clearing, airbag module resets, ECU recoding, ADAS camera calibration, and full software updates. Whether your vehicle is combustion-powered or fully electric, our technicians carry out every task with accuracy and efficiency. Our electrical specialists repair damaged wiring looms, replace faulty sensors, and reset lighting systems—including advanced headlamp units. We also perform mechanical repairs such as suspension work, steering rebuilds, and brake overhauls. For hybrid and electric models, we provide safe isolation, high-voltage diagnostics, and battery health assessments. Once repairs are complete, we perform roadworthiness checks, pre-MOT diagnostics, and a full test drive to confirm everything meets safety and manufacturer standards.
