    Frequently Asked Questions

    How long do diagnostic inspections and vehicle health checks take?

    Most diagnostic inspections and vehicle health checks take around 45-60 minutes depending on the vehicle or the nature of the fault.

    What’s included in a diagnostic inspection?

    We scan all major systems for stored or active faults, test sensors, and inspect key electrical and mechanical components for issues.

    What’s included in a Vehicle Health Check?

    We carry out a full safety and condition review: interior compartment, engine compartment, wheels and tyres, bodywork and exterior, front suspension, brakes & steering, rear suspension and brakes, exhaust system & road test.

    What’s the difference between a Diagnostic Inspection and a Vehicle Health Check?

    Diagnostics focus on fault codes and system performance, while a Health Check covers a broader visual and safety assessment of your car’s condition.

    Will you tell me what’s wrong with the car?

    Yes, we’ll explain exactly what’s been found, and walk you through the steps to rectify the problem, and give you a free no-obligation quote for the repair.

    Can you fix the issue on the spot?

    In most cases, yes. However, this depends on the repair that’s needed, part availability and our schedule for the day. If it’s a common fault, we usually have the tools and parts ready, so we can often complete the repair during the same visit.

    Can you clear warning lights?

    Yes. During a diagnostic inspection, we’ll safely clear any diagnostic codes and verify that the fault has been fully resolved.

    Can you inspect or check hybrid or electric vehicles?

    We’re able to inspect and check most hybrid and mild-hybrid vehicles. For full EVs, we advise you to contact an EV specialist.

    Can you check for engine or gearbox faults?

    Absolutely. We diagnose issues across all key systems including engine, gearbox, transmission, fuel, emissions, and electrical.

    Does this affect my warranty?

    No. Our diagnostic inspections are non-invasive and fully compliant with manufacturer warranty requirements.

    Can you carry out diagnostics at my home or workplace?

    Yes. We’re fully mobile and can carry out diagnostic inspections and vehicle health checks at your home, workplace, or the vehicle’s current location
