For the last couple months I've been getting a strange beeping noise in my 05 XT. At first i thought maybe someone left their phone in my car, and it's beeping because the batteries are dying. My wife thinks it's the radio.
Now i'm almost entirely convinced it's the ECU. Anyone else ever have this issue, or know of something similar?

I have just purchased on 05 XT and have also been hearing a soft beeping noise which I can't pinpoint. the doesn't seem to be any pattern to it. Seems pretty random. Chimes for a few seconds then stops. Any ideas?

I think I read a thread some time back about a seat belt warning beep that can be disabled.

you think it may be coming from the fob chirper in the front under the grill?

Thanks, I will try disconnecting this and see what happens.
I originally thought it was coming from inside, but maybe its not.
Cheers

The only "ECU" noise I hear is a computer hard-drive like sound coming from somewhere in the engine bay when the engine is off, but the key is in the "on" position.

OK, So I unplugged the chirper and still have the noise.
I seem to hear it most when its quite while driving at at low speed say 10-30 miles.
Anyone have any other suggestions?

Any outcome ?

I have the same issue on my Forester my2007. Has there been a resolution for the OP?
It happens sometimes, not everytime, when I'm driving slowly, and it scares me - it sounds like a mobile phone beeping. It's not the seatbelt reminder, that sounds differently. It's more of a computer / phone noise.

thought I'll update this after speaking to the dealership (Bill Buckle in Brookvale/Sydney): they advised that this can happen when I have a bag or something on the passenger seat - apparently there are some kind of sensors in the seat that trigger the 'no seatbelt' warning beep, even if it's something as light as a bag. Not sure why this doesn't get triggered constantly, maybe I had just done the weekly shopping or something and the bag was heavier than normal. I'll keep an eye on this!

Oh yeah, thats happend to me before. The passenger seat has pressure sensors to determine whether to enable the passenger air bag. It also uses these sensors to monitor the passenger seatbelt so that the seatbelt chime isn't constantly going off.

When I was moving early last year, I had a bunch of stuff in the front seat and it was enough to trigger the passenger seatbelt warning, but not enough to activate the passenger air bag. Basically the car thought a kid was in the passenger seat without his seatbelt on, so I had to pull over and plug the seatbelt in or listen to it chime for the entire trip.

I have sense used the seatbelt trick to disable the seatbelt warnings after the initial seatbelt chimes on startup.
