1. What is a California Smog Check?
A California smog check is a mandatory emissions test designed to reduce air pollution by ensuring vehicles meet state emissions standards. The test measures the amount of pollutants your car emits, including:
- Hydrocarbons (HC)
- Carbon monoxide (CO)
- Nitrogen oxides (NOx)
- Particulate matter (PM)
The test also checks your Audi’s onboard diagnostics (OBD-II) system for any fault codes that could indicate emissions-related issues.
2. Do Audis Need a Smog Check in California?
Yes, most Audi vehicles in California require a smog check. However, there are exceptions:
- New Audis (first 8 model years) are exempt.
- Electric Audis (e-tron models) do not need smog checks.
- Diesel Audis (2015 and newer) require a smog check but follow different testing procedures.
If your Audi is gas-powered and over 8 years old, you must get a smog check every two years or when transferring ownership.
3. How Often Do Audis Need a Smog Check?
- Biennial Smog Check: Required every 2 years for most Audis (when renewing registration).
