A Mercedes-Benz can store faults in dozens of control units, while the dashboard shows only a few warnings. A proper diagnosis reads all of them, separates current faults from old ones, and then confirms the cause with hands-on tests. At Orange Auto in Al Quoz and Nad Al Hamar we combine a full scan with Mercedes diagnostic software, a physical inspection of the engine, gearbox, brakes, suspension, steering, cooling and electrics, and a road test. You get a clear picture of what needs attention now, what can wait, and what is fine.
We start with what you have noticed: warnings, noises, smells, leaks or changes in how the car drives.
We read every control unit, from engine and gearbox to ABS/ESP, airbags, Airmatic and comfort systems, and check live data such as fuel trims, gearbox temperature and battery voltage.
We look for oil and coolant leaks, check fluid levels and condition, belts, hoses, the battery and charging system.
We inspect brakes, suspension, steering joints, driveshafts, the exhaust, the underbody and the tyres.
Where a fault needs confirming, we run specific tests such as smoke, pressure or current-draw tests.
We check engine response, gear changes, braking, steering and noises that only show on the move.
We go through the results with you, ranked as urgent, soon or monitor, with prices for anything you choose to fix.
Buying a used Mercedes? Our Mercedes pre-purchase inspection is built for that, with extra checks on history and hidden damage.
Basic readers see engine codes only. Many Mercedes faults live in other control units and need brand-level software to read.
Several warnings together often point to one cause, such as low voltage. See Mercedes electrical repair.
An inspection before a long drive or the summer heat catches cooling, tyre and battery problems early.
If your Service A or B is due, we can combine it with the inspection. See Mercedes minor service.
How long does a full inspection take?Usually a few hours, longer if a fault needs detailed testing.
Will you clear my warning light?We clear it only after finding and fixing the cause, otherwise it will come back.
Do I have to do the repairs with you?No. You get the findings and the choice is yours.
