2014 W212 Handbrake light stays on & Parktronic not working
I have a strong belief that the Parktronic issue could also be related to the CAN BUS.As for the footbrake, how can i verify it could be a mechanical issue?It’s possible that last night I pressed the footbrake pedal one extra click. Could that have caused anything on the footbrake? I figured it wouldn't be wise to risk it so I drove my secondary car.Thanks

In my car (2010 model) if I just slightly touch the foot pedal with my foot (happens very easily and often) the brake light comes ON.
I have not looked into this as the light clears every time I pull the brake release.
The switch is most likely of a kind that it sees the brake in home position so if the light does not clear it means the brake mechanism that the pedal moves does not quite come to the switch or the switch has moved or perhaps the switch is bad?
The parking sensors not working may be a result of the brake light being ON.




I once had a mild 2 click only on the parking/hand brake , was on an alignment rack. I then reverse, forgot that I had my parking/hand brake as 2 clicks does not feel any braking effect.
I reverse back to a half wall and waited , why parkings sensor not working ???
It has the parking/hand brake.Same strategy for wipers, with hood/bonnet unlatched, wipers won't work.









Either clean sticky grease or replace new PB.

Aint that sweet.I once had my brake switch came off its seating.
It was itchy hand of mine during work under the steering.




Does the Parktronic work now?
Quick fact, the REAR parktronic were actually working in some occasions, even without the footbrake sensor.
