Diagnostic Test
The initial booking covers the diagnostic test. If a fault needs further investigation or repair, we will explain any additional work and cost before proceeding.
Useful reasons to book
- An engine, emissions, ABS or other warning light
- Intermittent running or starting problems
- Reduced-power mode
- A fault message that has recently appeared
Further investigations
Open-ended investigation time is not shown as a public online service. Where more workshop time is needed, our team arranges it directly with the customer.
Interpreting the fault information
A diagnostic computer can read available fault codes and vehicle-system information. Our technicians use those results alongside the symptoms and inspection findings to decide what to check next. A code is a starting point for investigation rather than proof that one named component must be replaced.
Questions about diagnostics
Will the initial test include repairing the fault?
The initial diagnostic appointment covers the test shown above. If the cause needs extra investigation, parts or repairs, our team explains that work and its cost before proceeding.
What should I bring to a diagnostic appointment?
Tell us which warning appeared, when the fault happens and whether it is intermittent. Details of recent repairs and any previous diagnostic report can help the technician understand the history.
Do I need a separate diagnostic booking with a Gold Service?
Diagnostic work is already included in the Gold and MOT & Gold packages. The booking journey prevents a separate diagnostic test being added to those packages.
