What is breakdown / mechanical diagnosis?
A mechanic investigates a breakdown or fault to find the cause, then quotes the repair. Describe the symptoms and any warning lights.
Signs you need it
- Car won't start or stalls
- Warning lights on the dashboard
- Unusual noises, smells or smoke
How it works
- Symptoms discussed
- Inspection and testing
- Cause identified
- Quote for the repair before any work
You can choose a workshop visit or have a professional come to your home, work or depot.
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.
- Time needed to find the fault
- Parts required
- Workshop or mobile
Tips
- Note when the problem happens
- Take a photo of warning lights
- Don't keep driving with serious warning lights
Why it matters
Finding the real cause first avoids paying for parts you don't need.
