A car diagnostic test at NWAutoHub in Derry is a thorough check of your vehicle’s electronic systems and key components using advanced diagnostic equipment.

Our technicians connect a professional diagnostic scanner to your vehicle’s onboard computer (ECU) to read any stored fault codes or warning messages. These codes help pinpoint issues affecting your engine, transmission, braking system, battery, sensors, emissions, and electrical systems.

A vehicle diagnostic check can quickly identify common problems such as:

• Engine management light faults

• Battery and charging system issues

• ABS and braking faults

• Airbag warning lights

• Sensor and electrical faults

• Emissions and performance issues

• Starting or running problems

Once we identify the issue, our team will clearly explain what the fault means, recommend any repairs or maintenance needed, and provide a straightforward quote before any work begins.

After repairs are completed, we can clear the fault codes and retest the vehicle to make sure everything is working correctly and your car’s onboard monitoring system is operating as it should.
