A vehicle diagnostics check involves using specialised equipment to scan your vehicle’s electronic control units (ECUs) for error codes, faults, and irregularities. This process helps identify specific issues affecting your vehicle’s performance, allowing for accurate and efficient repairs.

You should consider a diagnostics check if:

• A warning light, such as the check engine light, appears on your dashboard.

• Your vehicle is experiencing reduced performance, such as loss of power or stalling.

• You notice a sudden drop in fuel efficiency.

• Your vehicle fails an emissions test.

• You want to ensure all systems are functioning properly as part of routine maintenance.

A typical diagnostics check can take anywhere from 30 minutes to an hour, depending on the complexity of the issue. Our technicians will perform a full system scan and interpret the results to determine the necessary repairs or maintenance.

After the diagnostics check, our technicians will provide you with a detailed report outlining the findings. We’ll explain the results in simple terms and recommend the appropriate repairs or maintenance needed to resolve any issues.

While a diagnostics check can identify many issues related to your vehicle’s electronic systems, it may not detect all mechanical problems. However, it is an essential first step in diagnosing and resolving performance issues, and it often leads to further targeted inspections if necessary.

Even if no warning lights are on, a diagnostics check can be beneficial as part of routine maintenance. It helps ensure all systems are functioning correctly and can identify minor issues before they become more serious problems.

A diagnostics check can detect a wide range of issues, including:

• Engine performance problems

• Transmission faults

• Exhaust and emissions issues

• ABS and airbag system faults

• Sensor failures

• Fuel system problems

The cost of a diagnostics check can vary depending on your vehicle’s make and model and the complexity of the issue. At QCD Autocentre Brackley, we offer transparent pricing with no hidden fees, and we will provide a clear quote before any work begins.
