FAQ

Car Diagnostics in Atlanta, GA — Common Questions

Is a code reader the same as a diagnostic?
No. A code points to a system, not the failed part. Big Tee tests from there to confirm the real cause so you don’t pay to replace the wrong thing.
Can you diagnose my car where it sits in Atlanta?
Often yes — many diagnostics can be run on-site across the metro. Deeper testing may need the shop.
What do I get at the end?
A plain-English explanation of what’s wrong and a written quote — parts, labor, and total.
