Hello,

For some weeks with my E92 325d model year 2008, I had a strange double beep noise mostly at speed below 50 km/h.

It does not originate from the radio, I have tried with the radio disconnected.

Here is a small video with the noise:

Hope someone can help to get rid of the noise.

Do you have hour memo checked in idrive time/date? Its usually three beeps though.

Sorry the car is without iDrive and has a manual gearbox.

It is always double beeps, and occurs randomly at speeds below 50 km/h

Lots of info on double beeps:

Yeah that like is worthless. If you can pin point a link in that link then go ahead but there is no help there. One thought is an aftermarket alarm installed.. Did you just get the car?

Speed warning maybe? It sounds different on the idrive version but I don't know about non-idrive

I have had the car for 2 1/2 years.

According the documentation I got with the car, an original BMW alarm system was installed by April 2008, about 5 months after leaving the factory.

Bimmer.work indicates a 302 alarm system.

Now it sometimes beeps shortly after engine stop.

Theres a kick panel under the steering wheel with an emergency speaker in it. The panel is easy to drop, unplug this and see if issue resolves. I know this is not a fix but will point you to a cause. The speaker will throw a code for being unplugged (no check engine light). Thats my guess..

hi, I tried to pull the alarm system fuse, but still no success ( still beeping )

Under the kick panel I found no speaker, that could provide the beeps.

I seems like the beeping comes from center or passenger side !

Tunafish, so you went thru all the links on the link I sent, and they are all worthless?

That said, you must have a lot of free time, but you missed the point of my post, which is that a poster needs to search before posting.
