I have a 2018 E400 coupe. 44k miles.
Has been an amazing car love it to bits.

Strange issue can’t seem to figure out.

2 days ago the yellow Electric Park Break light come on.

Switch does nothing. The E-break engages and disengages when put into drive and after the car is shut off. Am getting power to switch i think as when I try to engage with the switch, I get the blinking read “PARK” light. (Here’s where it gets weird”

I have lost power to the buttons on the left and right side of the touchpad in the center “Auto on, Dynamic mode, seatbelt, EX. The dial works and so does the touch pad. (Even stranger)

The AC blows cold but not hard UNTIL I Adjust my seat or steering wheel! Even at full blast it will blow soft until I hit any of the seat adjustment buttons on the driver side.

Code reader pulls code

C100BFB (The Switch 'Electric Parking Brake' Has A Malfunction, There Is An Implausible Signal.)
and




B23AC64 (The Electric Parking Brake Has A Malfunction)

I also get “Starter Relay Voltage high”

please help not sure where to even start

Holy crap. And the bit about the AC...
This sounds like a farce, but I do believe you are serious.
