Frequently Asked Questions
What should I charge for diagnostics?
Most shops charge 0.5–1.5 hours at the labor rate ($75–200) depending on complexity. Free diagnostics attracts price shoppers and gives away your most skill-intensive work.
Should the diagnostic fee be waived if the customer approves repairs?
Common and effective: credit some or all of the diag fee toward the approved repair. You protect the fee's value while rewarding customers who proceed.
How do I explain diagnostic fees to customers?
Frame it as testing, not guessing: equipment, data subscriptions, and a trained tech isolating the actual fault — which prevents paying for parts the car did not need.
