Precise Diagnosis, Permanent Fixes
Accurate Diagnosis, Permanent Fixes
Modern vehicles depend on hundreds of sensors, dozens of control modules and kilometres of wiring. When an electrical fault appears, whether it is a warning light, a no-start condition or an unexplained behaviour, finding the real cause requires the right diagnostic equipment and genuine technical expertise.
At SNS Auto in Al Quoz, our auto electricians use OEM-level platforms to pinpoint every fault accurately. We identify the root cause before recommending any repair or part replacement.

Multi-System Electrical Diagnostic Scan
We scan every control module in your vehicle, not just the engine. Our diagnostic process covers full fault code reading across all systems, live data monitoring, and CAN bus and LIN bus communication testing. You receive a written diagnostic report before any work begins.
Battery Replacement & Coding
Dubai heat kills batteries in 2-3 years. We test, replace, and code new batteries for BMS-equipped vehicles like BMW, Mercedes, Audi, and Porsche. Proper coding prevents ECU undercharging and ensures your battery lasts.
Alternator Diagnosis & Replacement
A failing alternator drains your battery while driving. We test charging voltage and output under load, inspect drive belts, and replace components as needed, followed by a full post-repair charging system verification.
ECU & Control Module Repair
We diagnose ECU faults, test circuits, and repair or replace modules including the BCM, Transmission, ABS, SRS, and climate units. All replacement modules are programmed and coded to your specific VIN before completion.
Wiring & Short Circuit Repair
We trace short circuits, open circuits, and high-resistance faults using manufacturer diagrams and voltage-drop testing. We expertly repair rodent-damaged wiring, water ingress issues, and problematic aftermarket accessory installations.
Sensor Diagnosis & Replacement
We diagnose and replace O2, MAF, MAP, crankshaft, camshaft, knock, and parking sensors. We always confirm that the sensor is genuinely at fault through thorough diagnostic testing before recommending replacement.
Vehicle Lighting Repair
We repair all lighting system types including HID xenon, LED headlights and DRLs, adaptive headlight modules, brake lights, interior ambient lighting, and fog light wiring. All faults are accurately diagnosed before replacement.

Frequently Asked Questions — Car Electrical Repair Dubai
Why does my car battery keep failing in Dubai?
Dubai heat above 45 degrees Celsius accelerates internal battery plate corrosion and causes electrolyte evaporation, reducing battery life from a typical 4 to 5 years in cooler climates down to just 2 to 3 years in the UAE. Short city trips that do not allow a full recharge worsen the problem further. If your battery is over 2 years old, have it load-tested at SNS Auto.
What is battery coding and do luxury cars like BMW and Mercedes need it?
Yes. BMW, Mercedes-Benz, Audi, Porsche, Bentley, Rolls-Royce and Maybach use Battery Management Systems that must be updated when a new battery is installed. Without this coding step, the ECU continues charging the new battery as if it were the old worn unit, causing persistent undercharging and early failure. SNS Auto performs battery coding as a standard part of every battery replacement on these vehicles.
My check engine light is on but the car drives fine. Should I be concerned?
Yes. A check engine light always indicates an active fault code stored in the ECU. Even if the car feels normal today, stored faults relate to engine, emissions or sensor issues that typically worsen over time. Active fault codes can also cause an RTA inspection failure in Dubai. We recommend a diagnostic scan within 1 to 2 weeks.
Can you trace an electrical short circuit on any vehicle brand?
Yes. We trace wiring faults systematically using manufacturer circuit diagrams and voltage-drop measurement to locate the exact wire, connector or component at fault. This applies to all brands in our service list including Ferrari, Lamborghini, Maserati and other specialist vehicles.
