Question 1

What does a check engine light mean?

Accepted Answer

A check engine light can indicate anything from a loose gas cap to a serious engine challenge. The light itself doesn't tell you what's wrong — it just signals that the vehicle's computer has detected an issue. A proper diagnostic scan reads the trouble codes and helps identify the root cause. Don't ignore a check engine light, especially if it's flashing.

Question 2

Can I drive with a check engine light on?

Accepted Answer

It depends on the situation. A steady check engine light often indicates a non-emergency issue that should be addressed soon. A flashing or blinking check engine light indicates a more serious challenge — often a misfire that can damage the catalytic converter — and you should reduce speed and bring the vehicle in as soon as possible.

Question 3

How much does a diagnostic test cost?

Accepted Answer

We charge a diagnostic fee that is applied toward the cost of any repair we perform. We'll explain the fee upfront before beginning any diagnostic work. There are no surprises.

Question 4

Do you use dealer-level diagnostic equipment?

Accepted Answer

Yes. We use professional-grade diagnostic tools that provide the same depth of data as dealership equipment, at a fraction of the dealership price. For most makes and models, our diagnostics are just as comprehensive as what you'd get at a dealer.
