Catweazle Posted June 21, 2022 Share Posted June 21, 2022 My rear left keeps beeping when braking. A re-calibration or something similar would be great! Quote Link to comment Share on other sites More sharing options...

What warning are you receiving ? Quote Link to comment Share on other sites More sharing options...

Not saying this is the issue but worth checking. Ask someone to press the brake to see if all the lights work properly and that no other lights come on when braking. 1 Quote Link to comment Share on other sites More sharing options...

Catweazle Posted June 24, 2022 Share Posted June 24, 2022 Hi guys, Checked over the Brake lights, and they all seem to be working fine. Only does it with a passenger in front, or on a hot day weirdly. The paint is a bit flaky on it, but made sure there are no obstructions by removing loose bits and cleaning. Still does it randomly under braking. Does anyone know how accessible the rear sensors are? I don't have easy access uinder the car unfortunately, but happy to get dirty and slither under!

Are you sure its the actual sensor? there is a passenger sensor in the front seat that will chime if a passenger is not wearing a belt and that could have a fault that needs a new buckle? Do you get anything on the dash to suggest rear sensor? Quote Link to comment Share on other sites More sharing options...
Catweazle Posted June 24, 2022 Share Posted June 24, 2022 Yeah, deffo reverse sensor as I have a funky led image of the 4 corners of the car that light up. I can turn it off, but obvs I would like it to continue working as it was. Quote Link to comment Share on other sites More sharing options...
