Diagnostics FAQs
01
How long does a diagnostic check take?
Typically 30 minutes to 2 hours, depending on complexity. We aim for same‑day diagnosis where possible.
02
Do you just scan and leave?
No, after scanning we interpret faults, explain what’s wrong, and present repair options. You decide what to do next.
03
Is diagnostics expensive?
We provide a quote before doing any work. Diagnostics usually pay off by avoiding guesswork and unnecessary replacement of parts.
04
Will you repair after diagnostics?
Yes, if you approve, we can do the necessary repairs or part replacements and retest.
05
Can diagnostics find every fault?
Most modern issues generate codes or clues. Some faults (mechanical, intermittent) may require further inspection beyond just scanning. We combine scanning + hands‑on checks where needed.
