I had to disconnect my spoiler third brake light,( not oem spoiler) it was blowing out the brake switch fuse, thanks for this post , i also replaced the switch just in case. Now to find out why its blowing it out.

 

I am having the same problem. I unhooked my 3rd brake light and changed my brake light switch and fuse. It worked for a min then I checked later on and blew the fuse right away.

 

So you are having a short somewhere,, mine was shorting out because i had an aftermarket spoiler ,,the spoiler brake light was connected to the oem 3rd brake light...i disconnected the spoiler one and everything works now.

 

Yeah I just tore all of the carpet out and didn't find anything but I made my harness hang down so I can stop blowing fuses til I find out what the problem is on Sunday

 

I'm currently having the same issues as the OP; VDC, Slip, Brake light comes on at first touch of the brake pedal. Last night I had a friend plug in his OBDII scanner to see if it was throwing any codes. Sure enough, the code received was P1805 - "Brake pedal position (BPP) switch - circuit malfunction"

Has anyone else seen this?

Two weeks ago I cut open the rubber hose between the body and the trunk and re-spliced (soldered and insulated) three wires (2 grounds and a power line to the trunk release actuator). That fixed me issue with the trunk actuator popping open. When I did this I did not see any other wires that were damaged or spliced, but since I don't have a spoiler, I don't really expect this to be the problem.

Just not sure if the brake pedal switch is the culprit, or if I somehow missed a fragile wire. ?
