What the price usually includes
- Reading fault codes with a scan tool
- Checking live data and testing the system the code points to
- A report of the likely cause and the repair needed
What changes the price
- Code scan only, or diagnosis to confirm the cause
- Intermittent faults that take longer to reproduce
- Specialist equipment for European, hybrid or diesel vehicles
- Mobile call-out or workshop visit
How to get quotes you can compare
- Note which warning lights are on and whether they flash or stay solid
- Say when the fault happens: cold start, at speed, when braking, in the rain
- Add any codes you already have
- Ask whether the diagnostic fee comes off the repair if you go ahead
Why there is no single price
Two cars that look alike can need different parts, oils or labour time. A quote based on your vehicle and what is actually wrong is the only reliable number, so post the details and let local businesses quote.

Questions
Can I just get the codes read?
Yes, but a code usually points to a system, not a failed part. Proper diagnosis tests to confirm the cause before parts are replaced.
Is a flashing check engine light urgent?
A flashing light often means a misfire that can damage the catalytic converter. Reduce driving and get it checked promptly.
Is posting free?
Yes. Posting a job never costs anything.
