Check-engine light on, but the car drives fine? That's one of the most common reasons people call us. The light only tells you something is off. A code is a starting point, and clearing it just lets the light come back.
At the shop we plug in the factory diagnostic software for your make (Tesla Toolbox 3, BMW ISTA+, Mercedes Xentry, VCDS and others) to trace the real cause, including electrical gremlins like a battery that keeps dying. The quick scan is free, and you get a written quote before any work. Full diagnostics are $150/hr.
