I was driving the other day and noticed that every time I would go over ~85 mph a noise would sound out of the dashboard/speedometer. Very annoying and also concerning.

The only thing that I changed recently were the tires, from the Dunlop runflats to a set of brand new Continental Extreme Contact DW, but it would be very surprising if that's the reason! over inflation maybe?

Check out the video I posted of it:

Any takes?

 

What's the error message?

 

There's no error message, I just hear the noise when I go over 85 mph

 

could be the seal around your windshield, just coincidence that it happened now

 

kinda sounds like a whistling noise, which would mean its air related.

 

Never used it, but could it be the speed warning was turned on?

 

try pushing on the windshield glass when u get the noise

 

Good Point. I believe the speed alarm is a chime similar to seatbelt chime. can't remember exactly.

+1 Air related. AND Wear your seatbelt

When i was in at service one time my SA was tied up with a CPO vehicle that had the same thing happen and they'd been trying to pin-point the issues for days. lol

 

Yes I also thought it was the speed alarm at first, but looked at the menu and it was off. I turned it on and it is indeed a chime, not a whistling.

Never had any issues with the windshield, don't understand why would that happen, the car has only 52K miles. If it is the windshield, do I need to reseal it?

No chance it's tire related?

 

You need to get in the vehicle with a few people....perferably 1 female and try to listen carefully. 2 BMW tech's an SA and owner finally figured her issue out after replacing door seals and so forth...it was coming from a mis-aligment on the drivers side front door.........tell me how that's possible on a CPO. lol. Must have been an accident in the vehicle which was undisclosed.

I mentioned female because they have a good ear for these kind of things and once they've made up their mind, its made. So chances of them shifting to another area are unlikely.
