FAQs.
Common questions from Rockville drivers about engine diagnostics.
Is a free code read the same as a diagnosis?
No. A code points to a system, not the exact fault. Proper diagnostics confirm the real cause so you fix it once.
Can I still drive with the light on?
A steady light is usually okay for a short trip to us; a flashing light means stop driving and call.
How much does diagnostics cost?
Call us at 301-401-6669 — we'll explain the diagnostic fee and apply it toward the repair.
