The trunk switch of the A3 is located below the driver's side door. To open the trunk lid of the Audi A3, you can also use the trunk release button on the remote key fob. The 2019 Audi A3 has a trunk capacity of 380 liters, which can expand to 1,220 liters when the rear seats are folded down. The A3 is a compact car with a body length of 4,554 mm, width of 1,814 mm, height of 1,429 mm, and a wheelbase of 2,680 mm. In terms of power, the A3 is equipped with a 1.4L turbocharged engine paired with a 7-speed dual-clutch transmission, delivering a maximum power of 150 kW (150 horsepower) and a maximum torque of 250 Nm.

I remember when I drove the A3, the trunk switch was usually near the floor mat in the driver's footwell, either a small button or a lever-style switch, making it easy to operate from the driver's seat. If you have a newer model with a power trunk, the switch might be near the dashboard on the center console or directly on the trunk lid as a button. The remote key also has a trunk icon button—press it twice, and it pops open automatically, which is quite convenient. If you can't find it, don't panic—just check the owner's manual; it has detailed diagrams. I once overlooked it myself and ended up searching manually for a while, only to realize it was right where it was supposed to be. Cars are designed this way for safety while driving, preventing distractions by reaching back, so maintaining practical habits can save a lot of hassle.

When performing maintenance on the A3, the location of the trunk release varies by model year: older versions typically have a physical lever button on the inner side of the driver's door pillar, while newer electric versions often feature a button on the trunk lid or key fob. As a common maintenance point, if the switch malfunctions, first check for dirt or debris obstruction. The design prioritizes easy emergency access, minimizing the need for external operation risks. For example, during rainy weather, I've found using the key fob button much faster than manual operation. Note that hatchback A3 models may have slightly different switch placements, but the core principle remains driver-area operation priority—don't overlook these details.

For my first time with the A3, I found the trunk switch on the left side—a small button under the driver's seat, easy to locate with a little exploration. You can also use the trunk button on the remote key; it's super simple. Don’t worry about complexity; the A3 is designed for practicality, with most switches embedded inside the car to prevent accidental touches. If you can’t find it, try the buttons near the steering wheel first. Stay patient—it’s usually in these spots, ensuring safe and comfortable use.
