Smog Check
Smog Check in Bayview, San Francisco
California requires a smog check every two years for most cars over six model years old, plus any time you sell a vehicle or register one new to the state. We have been doing smog checks in Bayview since 1996 and we know the test, the rules, and what to do if your car fails. Bring your renewal notice or your DMV transfer paperwork and we will take it from there.
What we test
Our test follows the BAR-OIS standard used at every California smog station. We pull live data from your OBD-II port, scan for stored emissions codes, verify your readiness monitors, and check the visual condition of emissions components like the gas cap, catalytic converter heat shielding, and EVAP lines. For older pre-1996 vehicles we run a tailpipe sniff test instead.
- OBD-II scan for stored and pending emissions codes
- Readiness monitor verification
- Visual inspection of emissions hardware
- Tailpipe analysis for pre-1996 vehicles
If your car fails
A failed smog check is not the end of the road. We diagnose the actual cause, give you a written estimate before any work starts, and re-test for free once the repair is done. Common failures we see in Bayview cars: bad oxygen sensors from short city trips, EVAP leaks from a loose or cracked gas cap, and catalytic converter inefficiency on higher-mileage Hondas, Toyotas, and Subarus.
How long it takes
Most smog checks take 30 to 45 minutes. If we are slammed we will give you an honest wait time when you walk in. If you would rather drop the car off, do that. We will text you when it is ready.
Why pick us
We are CA license #270008, family-owned since 1996, and the Bureau of Automotive Repair has us as a registered station. We do not upsell smog repairs that you do not need. If your car passes clean, you pay for the test and that is it.
