105 Series LC buzzer alarm (1 Viewer)

[Marto]

Greetings brains trust. I am a newbie here (posting from Australia) so lets start by saying thanks for having me. My 105 (2000 model) has an intermittent buzzer come on accompanied by the ABS warning light and the Handbrake light. My local LC specialist ran the OBD scan and the result came back saying 'battery too full'. So the battery was checked and it is tip top shape, not the problem. This buzzer is LOUD. Does anyone know a) where to find it b) what it looks like and c) how to disconnect it PLEASE I am going mad

This sounds like the warning buzzer for the ABS motor, which is well documented here. Seems unlikely that this is battery-related.

Do you have a conventional brake booster under the hood, or do you have the large reservoir with the motor and pump assembly? How do your brakes feel? Note that if you go on a test drive and the ABS motor stops, you will have very soft brakes that will require 3 pumps to slow the vehicle, so use caution.

Hi Steve, thanks for your suggestion. I have been driving safely with this buzzer going off intermittently for 5 maybe 6 weeks. Offroad, open road and city roads, the breaks are working great, no change there. I don't believe it is a brake related issue (strange as that may sound)
