If your vehicle fails, we provide a detailed written diagnostic report on the spot listing every fault code and emissions-related deficiency. Our technicians will walk you through repair options and pricing before any work begins. Once repairs are complete, we can perform an on-site retest — no need to drive to a separate station. Most Gold River customers are back on the road legally the same day.

Pricing is transparent and posted upfront. You pay a flat service fee based on vehicle type and model year, plus the state DMV certificate fee when applicable. There are no hidden charges — what we quote is what you pay. Check our Specials page for current promotions, including bundled pricing when you combine a diagnostic with an oil change or multi-point inspection.

Yes. Out-of-state vehicles registering in California are required to pass a California-standard emissions diagnostic before receiving in-state plates. We perform full VIN verification and generate the required diagnostic report for DMV submission. Our equipment meets all CARB specifications so your paperwork is accepted without complications.

Fees are tiered by vehicle model year and type. Older vehicles with higher emissions thresholds are charged differently than newer OBD-II compliant models. The state DMV certificate fee is separate and is collected at the time of certification. We publish current rates on our pricing page — no surprise add-ons at the counter.

Check your DMV renewal notice carefully. If it indicates your vehicle requires a 'STAR' or advanced diagnostic station, a standard smog shop cannot certify you — you must come to a facility like ours. 916 Auto Repair is a designated advanced diagnostic station, which means we handle the high-emitter profiles and gross polluter referrals that regular shops turn away.

A standard diagnostic inspection takes about 20 to 30 minutes for most gasoline-powered passenger vehicles. Diesel inspections or vehicles with complex fault codes may take slightly longer. Walk-ins are welcome during regular business hours, and we have a comfortable waiting area with Wi-Fi. If you prefer a guaranteed appointment slot, booking ahead is the fastest path.

Yes. We have the specialized equipment and CARB-approved testing protocols for diesel emissions diagnostics on both light-duty trucks and heavier passenger vehicles. OBD-II based testing covers newer diesel models, while older trucks receive a visual inspection of emissions components including the EGR system, DPF, and exhaust opacity.

A check engine light is an automatic failure on any California emissions diagnostic — the vehicle cannot be certified while the light is illuminated. Stored or pending fault codes must be diagnosed and cleared, and the vehicle's OBD-II readiness monitors must complete a full drive cycle before retesting. We diagnose the underlying cause and repair it so your monitors can reset correctly, avoiding failed retest attempts.
