What is diagnostic scan?
Fault codes read with a diagnostic tool to help pinpoint a warning light or issue. A good first step before repairs.

How much does it cost?
The exact price depends on your vehicle and the job. On MYLES, each professional shows a fixed price, a starting price, a range, or sends a quote — so you can compare like for like before you book.

Tips
- A code points to an area, not always a part

- Keep a record of codes found
