Inspection and service content

What can the diagnostic appointment include?

The investigation is adapted to the symptom and the systems involved.

01

Customer symptom review

When the fault occurs, how often it happens and any recent repairs or events.

02

System scan

Relevant control modules are checked for stored and current diagnostic trouble codes.

03

Live data

Sensor values and operating information can be reviewed where useful.

04

Basic circuit testing

Accessible power supplies, grounds, signals or components may be tested within the booked time.

05

Technical interpretation

Fault codes are assessed alongside symptoms and test results rather than treated as automatic part replacements.

06

Road-test observations

Where safe and appropriate, the fault may be assessed under operating conditions.

07

Initial findings

The technician records what has been confirmed and what remains unproven.

08

Next-step estimate

Further diagnosis, parts or repairs can be quoted separately where required.

The diagnostic fee covers investigation time

It does not guarantee that every intermittent or complex fault can be fully resolved within the initial appointment. Additional test time may be recommended before parts are replaced.

Helpful information

Common reasons to book diagnostics

Describe the symptom as accurately as possible when booking.

Engine warning light

Emissions, ignition, fuelling, sensor or engine-management faults.

Limp or reduced-power mode

The vehicle limits performance because a control system has detected a problem.

Electrical fault

Battery drain, charging faults, inoperative equipment or communication issues.

Intermittent running issue

Cutting out, hesitation, poor starting, misfire or inconsistent operation.

Before your appointment

Information that helps diagnosis

Specific details are often more valuable than a general description.

Record the warning message or photograph the dashboard.
Tell us when the fault happens: cold, hot, accelerating or idling.
Mention recent repairs, battery replacement or jump starting.
Do not clear the warning light immediately before the appointment.
Provide both keys if the fault may relate to starting or security.
Ensure there is enough fuel for testing and a possible road test.
Service FAQs

Common questions about Vehicle Diagnostics

Is a fault-code scan the same as diagnostics?

No. A code is a starting point. Diagnosis uses symptoms, live information and testing to determine what the evidence actually supports.

Will the repair be included in the diagnostic price?

No. Parts and repair labour are quoted after the initial findings.

What if the fault is intermittent?

Intermittent faults can require additional time or repeat testing. Provide as much detail as possible about when the problem occurs.

Can I approve the repair online?

Yes. The team can send an itemised quote to the customer portal.
