The interior light of the Audi Q2 not turning on after opening the door is caused by incorrect switch mode settings. Switch failure: Over time, switch wear, poor contact, corrosion, or aging can cause the rear light to not illuminate and result in poor contact. The detection method involves setting the multimeter to the 200V voltage range, locating the light wires, and inserting the two probes into the positive and negative terminals of the light wires. Turn on the power and operate the switch to check if there is voltage displayed. If no voltage is displayed, the switch might be faulty. Locate the headlight switch wire and use a wire or metal tweezers to short-circuit the switch wire. If the light turns on, it indicates a faulty switch. Bulb failure: Most bulbs are "filament-type" bulbs. Driving on uneven roads or prolonged use can cause the internal filament to break or burn out, resulting in the light not turning on. The detection method involves unscrewing the bulb and observing whether the filament is broken. Typically, bulbs have two filaments—one for the headlight and one for the brake light. If one is broken, it could be the cause of the issue.
