Emissions Testing & Repair in Cumming, GA
Auto Haus Solutions is not an official state emissions testing station — the test happens at Georgia's Clean Air Force stations. We diagnose and repair what fails the test. In Forsyth County, most 1999-and-newer gasoline vehicles need an annual emissions test to renew registration, and the top reason cars fail is the check engine light.
Any illuminated check engine light is an automatic failure in Georgia. Other common failures: worn catalytic converters, lazy oxygen sensors, EVAP leaks, and “not ready” monitors after a battery replacement or code clear. We fix all of it and get your monitors set — so you pass the first retest.
What Fails an Emissions Test
- Check engine light on — any stored code is an automatic fail
- Failing or degraded catalytic converter
- Oxygen (O2) sensor faults or slow sensor response
- EVAP system leaks (gas cap, purge valve, vent valve, or charcoal canister)
- Readiness monitors showing “not ready” after clearing codes or replacing the battery
Clearing codes the day before the test does not work — freshly cleared monitors read “not ready,” which fails on its own. The fix has to be real, followed by a proper drive cycle. Start with a check engine light diagnosis.
How We Get You to a Pass
- Read your failed test report or scan the vehicle
- Diagnose the root cause, not just the code
- OEM or better parts: converters, O2 sensors, EVAP components
- Complete the manufacturer drive cycle to set readiness monitors
- Verify with our own scan before you head back to retest
Bring your failed emissions report — it tells us exactly what failed. Most repairs are same-day or next-day with our 2-year / 24,000-mile warranty. Pair the visit with an oil change. See all of our European repair services.
A Note on Catalytic Converters
Converter replacement is the repair people dread, and the quote varies widely — some European cars carry two or four converters. We install OEM or better direct-fit converters meeting EPA requirements, but only after showing you the data proving the converter is actually dead. Many “bad converter” codes are really exhaust leaks or lazy upstream O2 sensors — on VW and Audi models especially.

Frequently Asked Questions
Do you perform the official Georgia emissions test?
No — we are not an official Georgia's Clean Air Force testing station. The test happens at official stations; we diagnose and repair failures and verify readiness so you pass the retest.
Will my car pass emissions with the check engine light on?
No — in Georgia, any illuminated check engine light is an automatic emissions failure. Diagnose and repair the fault first — that is the fastest path to a pass.
I cleared the code before the test — will I pass now?
No. Georgia stations check readiness monitors, and freshly cleared monitors read “not ready” — its own failure. We complete the drive cycle after real repairs and verify readiness with our own scan.
