How do you change a battery in an Audi A4?

Answer 1

Though not the best design - it is doable with simple tools. Note: my car is: Audi 2003 / 2004 Quattro A4 3.0

1. Remove weather stripping (3/4" thick strip across top of sheet metal between engine and fire wall (just give it a tug to get it going)

2. Remove plastic shield covering battery (remove the small one above the battery to give youself some leverage point). To remove the large plastic piece just pull up on the front edge of it first (along the entire edge) - there will be a metal clip or two unless they fell off. Then pull it out of the recessed edge (other side) - it comes out as one piece. Note where the metal clips were! :)

3. Lay cloth on side of car. :)

4. If you have time run to Sears (or local tool shop) and buy metric Allen heads for your nut-driver or socket set nut-driver. This will save you a headache....

5. Remove the positive and negative leads (I like to wrap the + cable in cloth so it doesn't touch anything....

6. My radio etc. were all fine. Alarm was fine so no need to do the battery trick...

7. If you don't have a nut-driver/Allen set (like me since it was Sunday night) just use a #6 Allen wrench with a ball tip (not necessary but helps)

8. The screw that holds the battery wedge in place is in a terrible spot - the front center of the battery. If they had only made a cut-out in the sheet metal this would be simple. But....they didnt' So use your Allen wrench along with some pliers to un-do the cap-head screw. Don't worry, it is locked into the plastic piece so it won't fall into the bottom of the engine compartment.

9. Slide the battery screw over out of the way

10. Remove the breather tube on the + side of the battery

11. Tilt the battery backwards, slide it out - Again, Audi, just another 1/4" here would have been nice!!! you may have to cut the zip-tie on the + cable cover to get the battery out. I did.

12. put new battery in

13. Replace all the gear in reverse order.

14. Return your battery core to the store for your refund (US)

15. Don't buy a Toyota next time! :) Audis are beautiful cars that perform like no others...

Hope this helps! -mrd

im in the same boat and have half the answer...

remove the weather stripping from the big plastic thing and bull the plastic cover off with force. The battery is secured by a mysterious screw that is very hard to reach and that's what is killing me.

good luck... next time im buying a Toyota!
