Questions drivers ask
Is a free code scan the same as a diagnostic?
No. A free code read at a parts store gives you a code, not a diagnosis. A diagnostic traces what is causing the code. Ask the shop what testing the fee includes.
Will the shop credit the diagnostic fee?
Some shops do if you have them do the repair, and some don't. Ask before you agree to the diagnostic. Get the answer on your written estimate.
Can I drive with the check engine light on?
The facts here can't say how safe it is for your car. Check your owner's manual for what the light means. If the light is flashing or the car runs rough, ask a shop before you keep driving.
