Wiring, battery, and COMAND or MBUX diagnostics for Mercedes models in Al Quoz. Genuine parts, upfront pricing, and free pickup and delivery across Dubai.
Mercedes' electrical architecture runs through multiple interconnected control modules, and a fault in one area can trigger warning lights that point to something else entirely. A generic garage without the right diagnostic tools often ends up guessing or replacing parts that aren't actually faulty. At our Car Workshop Dubai location in Al Quoz, we trace the actual fault before recommending any work.
Mercedes owners bring their cars to us from every part of Dubai for electrical repair, because an intermittent fault left undiagnosed usually gets worse over time. We inspect the car, agree a clear price with you, and only start once you approve it. Your Mercedes is collected and delivered back for free, anywhere in the city.

What we see most often
Common Mercedes Wiring & Sensor Faults
Dubai's heat puts extra strain on wiring, connectors, and batteries. These are the faults we trace most often on Mercedes models in our garage in Al Quoz.
Car won't start
Can point to a weak battery, a faulty alternator, or a starter motor fault, needing proper diagnosis.
Battery draining overnight
Usually points to a parasitic draw from a faulty module or component left drawing power.
Dashboard warning lights on
Needs a proper diagnostic scan to trace the exact module or sensor behind the warning.
Windows or mirrors not working
Can point to a faulty switch, motor, or a wiring fault in the door loom.
Headlights or interior lights flickering
Usually points to a loose connector, a failing bulb driver, or a voltage regulation fault.
COMAND or MBUX freezing
Can point to a software fault or a failing control module, needing a proper scan to confirm.
Key fob or central locking issues
Often a battery, module, or wiring fault in the locking system, worth checking properly.
Intermittent electrical faults
Faults that come and go are often the hardest to trace, and need proper diagnostic equipment.

At our Car Workshop Dubai location in Al Quoz. We diagnose and repair Mercedes electrical systems, with free pickup and delivery anywhere in Dubai.
Dashboard warning lights, a car that won't start, flickering lights, or a battery that drains overnight are the most common signs. Any of these are worth getting checked properly.
It depends entirely on the cause, a single sensor fix costs far less than a full wiring or module repair. We diagnose first, then send you a clear price on WhatsApp.
Mercedes' modules are interconnected, so a fault in one system can trigger a warning that looks like it belongs to another. A proper module scan traces the actual source rather than guessing.
Yes. Intermittent faults take more time to trace since they don't always show up during a single scan, but our diagnostic process is built to identify them properly.
Yes, we test and replace batteries as needed, and correctly code the new battery to your Mercedes' electrical systems so everything continues working properly.
A single confirmed fault is often fixed within a day. A more complex or intermittent issue can take longer, and we'll give you a clear timeframe once we've diagnosed the car.
Yes, anywhere in Dubai. We collect your Mercedes, carry out the work, and bring it back to you at no extra cost. Just share your location when you book.
