Is this normal wheel speed sensor noise for 2012 335i f30?

There is a screeching noise alternating between the wheels when driving at low speeds.



From what I understand the tire pressure monitors uses the wheel speed sensors for this task. Is this level of noise normal for this car? It seems a bit noisy..

Listen at 58 seconds at 1:10 for the sound. The other ones are more muted.

The speed sensors don't make contact with anything, so they can't make noise. They use magnets to read the speed of the wheels.

So there is no solenoid or anything that moves inside the sensor?

It's all electronic. I suppose some sort of crud could get caught up between the sensor and the hub, but brakes are far more likely to be the source of noise.

at around 58 seconds can hear one and 1:10 into the video. It sounds like its alternating between wheels and don't believe it has anything to do with braking as it occurs without the brake being applied. This sound appears more than twice but the other ones are more muted as they were less close to the mic such as back corner wheel away from me and other wheels.
