What Happens During the Diagnostic Check?
Initial consultation – We start by discussing the issue with you directly. This helps our technician understand what you’ve noticed and gather useful background on the problem.
Visual and mechanical inspection – A full check of your vehicle follows, allowing us to confirm any symptoms and ensure nothing obvious is missed.
Computer system scan – We connect to your car’s ECU (Electronic Control Unit) to access current and stored fault codes, helping us pinpoint where issues may be originating.
Technical bulletins & software checks – We look up known faults for your specific make and model and identify any relevant software updates that could influence the fault.
Live data analysis – Our technician evaluates the information gathered from the onboard systems to spot unusual readings and plan out the next diagnostic steps.
Reference to technical diagrams – We consult detailed wiring diagrams and system schematics to understand how individual components interact and guide testing.
Targeted system testing – Using professional-grade diagnostic tools (such as oscilloscopes, flow gauges, and data loggers), we perform logical, step-by-step tests to locate the root cause.
Clear results & next steps – Once testing is complete, we compile the results into a clear diagnosis and get in touch with you to explain what we’ve found, along with any recommended fixes.
