If your Aud battery is dead, the keyfob will not work. Remove the metal key from the keyfob and manually open the driver's door. For more help on how to remove the metal key from the keyfob watch these videos on this guide.
Step 1: Turn off the ignition
Remove key from the ignition. Modern cars are very sensitive to voltage drops and Audi models such as A3 A4 A5 S6 Q5 TT models are no exception. To avoid electrical problems, make sure the ignition is turned off.
Step 2: Open Hood
Open the hood. Locate the hood release underneath the dash. Pull the lever until you hear the hood pop open. Next, you need to release the hood safety latch at the front of the hood.
Step 3: Locate Battery
Locate the terminals where you can jump start your Audi. Avoid connecting the jumper cables directly to the battery. Instead use the jump starting terminals.
Audi A4 and Q5 postive jump start terminals.
Step 4: Determine Jump Terminals
Here is the positive terminal. Connect the jumper cables here if your Audi does not have a separate positive post shown in the previous step. On this terminal, you can connect the red clamp from your jump box or the red clamp of the jumper cables.
Step 5: Connect Neg. Jumper Cable
Here is where you can connect to the negative terminal.
A bolt on the strut tower or dedicated post can also be used to connect the negative cable (black clamp).
Step 6: Jump Start Audi
Next, determine which method you will use to jump-start your car. If you are using a jump box, you simply need to turn it on. The other option is to jump-start your Audi with the help of another car.
Connect the jumper cables to the helper car. Red clamp goes on the red battery terminal. Black clamp goe son the negative battery terminal of the helper car. Start the helper car and let it idle for a couple of minutes.
Step 6: Start Engine
Start the engine. If the car won't start the first time, check the clamps to make sure they are making good contact.
Important notes to keep in mind when jump starting a car.
- If the car doesn't start or you hear a click, it means the clamps are not making good contact. Or the battery is so discharged, that it needs more juice. Check the clamps to make sure they are making good contact.
- When a helper car is being used, let the helper car charge your car battery for at least 15 minutes. Stay close to the vehicle and monitor the dead battery. If the dead battery starts to feel too hot, disconnect the jumper cables immediately.
- Once you get your car started do not turn it off right away. Drive it for let it idle for at least 30 minutes or more. If you turn the car off right away, it may need a jump start again.
- If your car battery is over 7 years old, it may need to be replaced. Especially if it is no longer holding a charge.
- Low voltage due to a dead battery can set various fault codes in modern vehicles. For exmaple, the airbag light may stay on after you jump start the car.
