The 12-volt battery in most Audi Q5 models sits in the front engine bay. If you own a Q5 TFSI e plug-in hybrid, the high-voltage traction battery is located under the rear-seat floor, while the 12V battery remains up front.
Understanding this layout matters for maintenance and safety: in non-hybrid Q5s the 12V battery is up front for easy access, while the hybrid variant adds a large HV pack under the rear floor to optimize packaging and weight distribution. Locations can vary by model year and market, so consult your owner's manual or dealer for your exact configuration.
Battery location in standard Audi Q5 models
For non-hybrid Q5 variants, the primary concern is the 12-volt system that powers electronics when the engine is off. Here’s where you typically find it.
- Gasoline and diesel Audi Q5 (non-hybrid): 12-volt battery located in the engine compartment at the front of the vehicle.
In standard Q5s, the 12V battery is most commonly in the engine bay at the front, some markets may have different arrangements but front-mounted 12V is the norm for service access.
Battery location in plug-in hybrid Q5 TFSI e
Plug-in hybrid variants pair a conventional 12V system with a high-voltage traction battery. Here is where each sits.
- 12-volt battery: located in the engine compartment at the front, similar to non-hybrid Q5s.
- High-voltage traction battery: located under the rear seat floor, within the cargo floor area (beneath the rear seating), to keep a low center of gravity and balanced weight distribution.
For Q5 TFSI e owners, the large HV pack is not in the trunk; it sits under the rear seating area. The 12V battery remains in the front. Always verify with your exact model year and market in the owner’s manual or with Audi.
Practical notes for owners and technicians
These notes cover safety, maintenance, and access considerations when dealing with the Q5 battery layouts.
- When replacing the 12V battery, follow Audi’s service procedure and disconnect the negative terminal first to avoid shorts.
- In hybrids, avoid placing metal tools near HV components; charging and servicing should be performed by qualified technicians.
- Access points: 12V battery typically under the hood in the engine bay; HV battery under rear seat floor in Q5 TFSI e; some markets provide access panels in the trunk floor for HV components.
Understanding the layout helps with routine maintenance, jump-starts, and safety checks; always verify with your VIN and manual.
Summary
In summary, the Audi Q5’s standard 12V battery is located in the front engine bay. In the plug-in hybrid Q5 TFSI e, the high-voltage HV battery sits under the rear seat floor, while the 12V battery remains up front. For exact placement, refer to your model year’s manual or check with an Audi dealer.
