What moves the price
- Complexity of the issue — an intermittent fault can take several test drives and checks to track down.
- Number of systems checked — a full engine, electrical and braking check takes longer than one system.
- Model of the vehicle — some makes need dealer-level diagnostic software that not every garage has.
- Diagnostic depth — reading fault codes is quicker than tracing a fault through wiring and live data.
- Mobile or garage visit — a mobile car diagnostics visit to your home can cost more than taking the car in.
- Access to components — sensors and wiring hidden behind panels take longer for the technician to test.

How to pay less
- Having the car diagnostics done at the same visit as a service can save paying for a separate check.
- Noting when the warning light or fault appears helps the technician find it faster, which can cut diagnostic time.
- Asking whether the diagnostic fee comes off the repair bill, if the same garage fixes the fault, can save money.
- A basic fault code read can cost less than a full diagnostic check when the warning light points to one system.
- Timely diagnostics can prevent further damage and costly repairs.
