WTF is this noise?

So I was working on my car in the garage this afternoon and I heard this pulsing tone coming from the right rear tire. It got louder underneath the car right behind the right rear tire. I even popped the trunk and it was quieter in the car. Key is in the off position and it did it with keys and and keys out … did not matter. Hard to hear on the video, so turn your volume up! 8)

Hmm, that is in the general area of your cars alarm system. Try unplugging it and see if it goes away.

I literally had this problem last night too after my battery died and I recharged it. I think its the gay ass weak ass alarm in these cars? I started my car up and turned it off. Locked the car and unlocked and it went away.

I did a quick search and found the alarm was a possibility. I locked, unlocked several times and it kept making the noise. I’ll have to tear out the ELSAWIN and find where the alarm horn is and see if that was it …

the interior motion sensor alarm is very easy to set off, a strong breeze can do it. may have triggered your alarm

I just checked ELSAWIN and the alarm horn is located behind the driver rear quarter panel … this noise was coming from the passenger rear quarter …

I found it! It was air purging from the gas tank … I unscrewed the gas cap and there was some pressure in there and the noise stopped immediately. ???

That’s interesting. Always nice to discover where the odd noises are coming from
