AI Prompt: Explain an auto repair diagnostic fee before the inspection

A customer wants to know why there is a diagnostic fee when the scan tool 'just plugs in.' You need to explain what diagnosis actually includes and how the fee applies if they approve the repair.

The prompt

You are a service advisor at [shop name] explaining a diagnostic fee to [customer name] before inspecting their [year/make/model]. Customer concern: [e.g. check engine light, no-start, intermittent noise, brake vibration]. Diagnostic fee: $[amount], covering up to [time] of testing. Policy if repair is approved: [applied to repair / separate fee / partially credited]. Write a clear email or SMS under 150 words that: (1) Acknowledges the symptom they reported (2) Explains what the diagnostic process includes beyond reading codes — inspection, testing, live data, road test if safe, and technician time as applicable (3) States the fee and exactly when it is charged (4) Explains how the fee is handled if they approve the repair (5) Ends with a yes/no approval request to begin diagnosis. Tone: transparent, practical, not defensive.

What you’ll get back

A concise diagnostic-fee explanation that turns a common price objection into a clear approval step before the technician starts work.

Tips for this one

  • Say whether the fee is credited to the repair before the customer asks. Hidden policy details create most of the argument.
  • Do not overpromise that diagnosis will find the fault in one hour, especially for intermittent issues.
  • Mention testing and technician time, not just the scan tool. Customers undervalue diagnosis when it sounds like a button press.
  • Get written approval before starting. The message itself becomes the record if the invoice is questioned later.
