C-Class mercedes c 200 active brake assistance warning

[Laksiri Gunawardena]

I recently acquired Mercedes Benz C 2900 F/L model and senn that "active brake assistance malfunction" warning appearing and its recommending me to consult a qualified technician. Vehicle has not done even 600km. Kindly share your experiences on this type of malfunctions.

It may be due to the following:

• 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

It is possible that this one can be solved with a software update.

Hi
Thx, Radar inoperative may be the cause, as it was recently removed and reinstalled to facilitate a front buffer change .
