Frequently Asked Questions
What does the check engine light mean?
The check engine light can indicate many things, from a loose gas cap to a serious engine issue. A diagnostic scan reads the specific error codes stored in your vehicle's computer to pinpoint the exact problem.
How long does a diagnostic take?
A standard diagnostic scan takes 30-60 minutes. More complex issues that require additional testing may take longer. We'll give you a time estimate upfront.
Do you fix what you find?
Yes! Once we diagnose the issue, we provide a detailed estimate for the repair. With your approval, our technicians can perform the repair right away in most cases.
