In most 2019 Audi models with traditional internal-combustion engines, the 12‑volt battery is located in the trunk under the cargo floor; some trims place it in the engine bay. For plug‑in hybrids and fully electric versions, the high‑voltage traction battery sits in a floor‑mounted pack under the cabin, while the 12‑volt battery location tends to follow the same general pattern as non‑hybrid models.
Non-hybrid 2019 Audi models: typical 12V battery location
The following outlines where you’ll commonly find the 12‑volt battery in various non‑hybrid 2019 Audi cars and SUVs. Locations can vary by model year, trim, and production changes, so verify with the owner’s manual or a dealer if you’re unsure.
- Most sedans and SUVs (such as A4, A6, A7, A8, Q5, Q7) place the 12V battery in the trunk under the floor panel or behind a removable trim panel in the cargo area.
- Some smaller models or certain trims may mount the 12V battery in the engine bay, typically toward the right side near the fender, especially if trunk space is prioritized elsewhere.
- In certain configurations, access to the battery is via a small side panel or cover in the luggage area, with the actual battery protected by a dedicated tray.
Bottom line: for most 2019 Audi non‑hybrid models, start your search in the trunk under the cargo floor, and if you can’t locate it, consult the owner’s manual or contact a dealer for the exact layout on your specific trim.
Electrified 2019 Audi models: plug‑in hybrids and electric vehicles
Electrified Audis add a high‑voltage traction battery in a floor‑mounted pack, while the 12‑volt battery’s location follows the same general pattern as the conventional models. Exact placements vary by model and drivetrain configuration.
- High‑voltage traction battery: mounted in a floor cavity between the front and rear axles, spanning under the passenger compartment. This arrangement keeps the heavy battery low and centered for handling and safety.
- 12‑volt battery: location mirrors the non‑hybrid layout for the respective model—often in the trunk under the floor or occasionally in the engine bay, depending on the specific hybrid or EV variant.
In electrified Audis, you’ll mainly be dealing with two batteries: a large high‑voltage pack for propulsion and a standard 12‑volt battery for accessories and starting. Check the exact model’s manual for precise placement and safety notes before attempting any service work.
How to locate your specific model’s battery
If you’re unsure about your particular 2019 Audi, the quickest path is to consult the official owner’s manual for your exact model/trim. You can also call a dealer or peek under the cargo floor in the trunk, where many 12‑V batteries are housed, or inspect the engine bay for a battery terminal cover that indicates the battery’s location.
Summary
For most 2019 Audi models with traditional engines, the 12‑volt battery is typically in the trunk under the cargo floor, with some trims placing it in the engine bay. Electrified models add a floor‑mounted high‑voltage battery, while the 12‑V battery location usually follows the same trunk or engine‑bay pattern as the gas versions. Always verify with the owner’s manual or a dealer for your exact configuration.
