Virginia emissions inspection: OBD readiness rules
Virginia emissions inspection (DEQ) plugs into the car's OBD2 port and checks its readiness monitors, the self-tests the engine module runs while you drive. Here's how many may still be not ready.
| Monitors allowed not ready | 2002 to 2022: 1 not ready |
|---|---|
| Check-engine light on | Fails |
| Model years tested in 2026 | 2002 to 2022 |
| Where | Northern Virginia |
Over the limit is a reject: come back once the monitors are ready.

Check your BMW before you go
In the AutoLingo for BMW app, pick Virginia under Settings, "State for emissions testing". Connect, and the Overview's "Inspection in Virginia" line says whether the car would pass, would not pass, or isn't tested, with the reason (for example, which monitor isn't ready). Step by step: check if your BMW is ready for an emissions inspection.
Monitors not ready? Follow BMW's drive cycle (about 25 minutes from a cold start), or drive normally for a few days, city and highway, and check again. They reset when the battery is disconnected or the fault codes are cleared, so don't clear codes just before the test.
