What Causes the Mercedes Radar to Not Beep?

[RowanAnn]

Mercedes radar not beeping reasons are as follows: 1. Whether the radar host line is loose: Check if the host's power cable is properly connected and if there is current; then check if the radar host line is loose. If neither of these is the issue, the problem may lie with the radar itself. 2. Buzzer damage: Another possibility to consider is damage to the buzzer, in which case you will need to purchase and install a new buzzer. 3. Wiring damage at the bumper: Check if the wiring connections at the bumper are intact, then check if the reverse lights come on when shifting into reverse. If they don't, inspect whether the reverse light connection switch is damaged.
