Installed a New Battery, What Are These?

[renold458]

Finally got around to switching my battery out and during the whole process I found these things lying around and doubt they should just be just flopping around.



This little guy was attached to the cabin air filter box and when I dropped the new battery in it caught on the cable and yanked this off. Wondering if it belongs there at all and how to reattach it as I cant figure it out.



This tube was also just flopping around, noticed it after I took the old one out and saw all that space and it was hiding behind the battery.




Old battery (top) and new battery (bottom). Ignore the terminals not being totally attached, they didnt want to go all the way down but I tightened them pretty well, probably going to replace those. I noticed there's a tube attached to the old one but it wasn't attached to anything in the car, should the new one have some sort of vent tube like that or am I fine the way it is?

I assume yours is a 2002 model so you have an air quality sensor that plugs into the cabin air filter box. On the right side of your battery you will see a small white plug. Remove the plug and insert the battery vent tube.

Looks like you need to pull the white plug on the side of the battery (above the red plus sign) and push the vent tube in.

Awesome, thanks guys. Where would I plug that sensor in? I couldn't find anywhere to snap it in.

I'm currently laying in bed posting with my cell phone so it's tough to link to pictures. Google A4 B6 air quality sensor images and you should find what you need.

Cool, I'll save you the trouble and look that up. Thanks again for the help.
