Active Brake Assist Display Message

Yesterday, I got this message on the display. It displayed for approx 10 seconds and then disappeared.

Active Brake Assist Functions Currently Limited See Operator's Manual

I looked it up in the manual. Below is what I found. The bottom line is, this message may appear on rare occasions. It's perfectly normal. It's only a problem if it continues to display. So if you get that same message, no need to panic.

Possible causes are:
  • The radar sensor system is temporarily inoperative, e.g. due to electromagnetic radiation emitted by nearby TV or radio stations or other sources of electromagnetic radiation
  • The system is outside the operating temperature range
  • The on-board voltage is too low.
  • On Mercedes-AMG vehicles, the ESP® is deactivated
  • Function is impaired due to heavy rain or snow
When the causes stated above no longer apply, the display message should disappear. Active Brake Assist is operational again. If the message does not disappear, this indicates a malfunction.

This happened to me today when driving fast on a windy road!car basically went into limp mode.
Restarted to get out of limp mode, but took 3rd restart after 10 mins to get rid of the CEL .
The car was idling uneven as well, then went back to normal after the 1st restart. Did this happen to you as well? Or again after this at all ?

We've had this happen a couple of times.

It's usually accompanied by one of two things:
1) dirty sensors
2) heavy rain

We have never gone into limp mode because of it though. I wonder if you don't have something else going on???

Thanks yes was confirmed today by the tuner. It was due to boost pressure exceeding tolerances , not properly raised by the new tune.

Hi,
So I kind of had the same issue. Driving fast then all of a sudden that message pops up and all acceleration and shifting ceased. I pulled over, the car had rough idle. I turn it off and back on and it is fine. I also am tuned by eurocharged and I'm trying to work with them to fix it but haven't had any luck with the 6 tunes we've tried. How did you fix this??

I have checked my car today. Disconnected the camera on the windscreen and reconnected it again. The issue goes away for 1 minute and comes back again.
Every one is talking about a software update. Dealers charge £150 per hour, but want to confirm if that is the case.

Any one who had this issue please do let me know.

Thank you very much
