Why Audi cars cause K-band false alarm?

[MasterApex]

I posting the question to general forum to get inputs.

My V1 will get erratic K-band signal when nearby Audi Q5, Q7, newer S5, etc.
Why these Audi cars generating K-band signal?

Thanks.

It is one of a whole generation of intelligent assistance systems on the A4, A4 Avant, A6, A8 and Audi Q7 model lines, as well as for the new Q5.

Audi braking guard forms part of the radar-based adaptive cruise control system, or ACC for short. This system regulates the speed and the distance from the vehicle in front at speeds between 20 and 155 mph, independently applying the brakes within certain limits in the process.

More and more manufacturers are using such systems, Mercedes Distronic come to mind, as well as RADAR based LDW (Lane Departure Warning/Blind Spot Warning) RADAR based systems.

Same issue when too close but I look at Frequency ID and if it is bouncing around I disregard because the cops K-Band is a steady 25.148-25.150Ghz. I also have the same problem as everyone else with Cobra as they emit a 33.6-33.7Ghz Ka-Band frequency, but since all the cops around here use 35.5Ghz I again disregard.

It is on more than just the Audi's.

Audi, BMW and VW use the same system from Hella
