Common Mercedes Problems We Diagnose

• Engine Management Light
The engine warning light can indicate anything from a faulty sensor to a serious engine issue, and we accurately diagnose the exact cause.

• Limp Mode
If your Mercedes has entered limp mode with reduced power, we identify the fault and restore normal vehicle performance.

• AdBlue Countdown
We diagnose and repair AdBlue system faults that trigger the countdown warning and can eventually prevent the engine from starting.

• NOx Sensor Faults
Faulty NOx sensors can cause warning lights, poor fuel economy, and AdBlue issues—we accurately test the entire system before replacing parts.

• DPF Blockage
Blocked Diesel Particulate Filters (DPFs) can reduce engine performance, increase fuel consumption, and trigger warning lights.

• Turbo Faults
We diagnose turbocharger problems, boost pressure faults, actuator failures, and related engine performance issues.

• Glow Plug Faults
Glow plug and control module faults can cause difficult cold starts, rough running, and dashboard warning messages.

• ABS Warning
Our Mercedes STAR diagnostic system quickly identifies ABS faults affecting braking performance, wheel speed sensors, and control modules.

• Airbag Warning
We diagnose SRS and airbag warning lights to identify faults with sensors, seat occupancy systems, wiring, or control units.

We diagnose automatic gearbox faults, shifting issues, transmission control units, and adaptation problems using genuine Mercedes STAR diagnostics.

From communication errors to wiring faults and control module failures, we provide accurate electrical fault diagnosis.
