Collision Warning System with Active Brake Intervention
On my 2015 ML400 I occasionally see a red warning light and hear a beep, usually when there's nothing in front of me lol, but I've never had the vehicle "self-brake". My Datacard does list "258 COLLIS.WARN. SYS. W/ ACTIVE BRAKE INTERV. FCW STOP" but I have had to jam on my brakes to avoid close call rear-end collisions. I do not have distronic. Could my "ACTIVE BRAKE INTERV." need service/adjustment/repair??

I am sure you've read the owner manual to guide you through the dashboard menus to enable these options, yes?
I am familiar with the beep-beep warnings in plain open roads. You can scan your chassis to collect the faults from the 3x front radars ghosting?
This is caused by unstable voltage transients as seen by main long distance radar.
Local MB specialist may be able to confirm what options to expect.

This will be limiting your car safety response:
unplug bad radars - No more positive or false trigger!
Beware:
Now you can drive without crazy breaking out of the blue... in this mode you are 100% in charge, radar interaction canceled.
Problem being the Front Radar Solderless circuit board need a 5mn soldering job. Chassis vibrations and heat work a bad number on purpose built electronic circuits.

The trouble is that I've become accustomed to the "nanny apps" in my SL and now I feel naked without them!

me too!
Now I totally rely on ESP and the SGW radar to manage my braking distance... that's why I wrote about new behaviors without radar.
Besides marginal solderless pins, the harness connectors are hardly sealed. Whenever exposed to rain projections... water can penetrate all 5 radar modules (front + back).... SILICONE RTV!!
The "Active BS" option allows the car to avoid collision by combining brakes + steering... I've experienced that once, very effective and welcome intervention.
