Mobile check engine light diagnostics in Denver

A warning light tells you something is wrong, not what. We come to the car with a professional scan tool, read live data, road test it, and give you a plain-language answer with a written quote before any wrench turns.

How it works

Quote first.
Then we roll.

Call, text or send the form with the year, make, model and symptom. You get a written quote with parts and labor broken out, usually same-day. We come to the car with the parts the quote calls for, and the finished job is road-tested.

Estimates are free. Diagnostic time is a separate charge and is quoted before we start.
