Describe it once. Matched providers come to you.
A fault code points to a system, not usually to a part. Good diagnosis means scanning, then testing to confirm before replacing anything. In the job, note which lights are on, whether they flash or stay solid, when the fault happens, and any codes you already have from a scan.
Common jobs
- Check engine and other warning lights
- Limp mode and loss of power
- Intermittent electrical faults
- Rough idle, misfires and stalling
- Pre-repair fault finding

Questions
How much does diagnostic scan cost in Auckland?
On AutoRepairs NZ, 6 local businesses list diagnostic scan from $50, GST incl. (November 2026). The final price depends on the vehicle and what it needs; post the job free to get exact prices from businesses who cover your suburb.
Can I just get the codes read?
Yes, but a code alone rarely identifies the failed part. Ask providers whether their quote covers a scan only or diagnosis to confirm the cause.
Is a flashing check engine light urgent?
A flashing light often indicates a misfire that can damage the catalytic converter. Reduce driving and get it checked promptly.
Is posting free?
Yes, for vehicle owners.
