M2 - occasional 'beep'

[T350 Brad]

I've got a pre-LCI M2, and intermittently when driving it 'beeps'.

For those with the Advanced Car Eye dash-cam it's a similar sound to the double-beep you get when it detects an 'event' (typically me driving over a speed-bump or pot-hole), only this time it is a single beep.

Nothing appears on the dash or on the nav screen so I've no idea what the 'beep' signifies.

Anybody have any ideas what it may be. I sometimes get two or three on some journeys and sometimes nothing!?!? I cannot find any common reason as to why it happens.

Any thoughts gratefully received.

The only beep I get is if the collision warning system is pre-loading the brakes for an emergency stop. It sometimes intervenes at really odd moments, often when there's a parked car on the kerb, even if I'm already steering to go around it. This is accompanied by a red light at the top of the dash though so if you don't get that then I don't know (although it can go on and off really quickly/could be obstructed by the top of the steering wheel, depending on your driving position).

A video of the sound would help, a quick google found this thread, no idea if its the same though.

Apols if I'm stating the obvious but the car will beep once when the temp is less than 3 C when starting the car or if it drops to 3 C when driving.

Does it have a wireless phone charger? Mine occasionally gets itself into a hissy fit and bleeps once in a while.

Thanks for all the replies. It's definitely not the temp warning 'chime' as i'm familiar with that sound (and the on-dash message), or the collision warning (as again I can see the red warning light when it flashes up).

Will have a read of that thread - hopefully it can shed some light!

How does the wireless phone charging work? The car came fully loaded with pretty much every option so (assuming it's an optional extra) it could be linked to that!?

Just read the thread - their problem seems to be a mechanical 'chirp' / beep - mine is just a single beep every now and again that is the car seemingly signalling some kind of notification / wanring .. just no idea what it's trying to tell me!!

Unfortunately I can't film it as most journeys it doesn't happen - just very randomly it will beep! Sometimes two or three times in one journey...!?
