The air pressure is good (brakes do not engage). Most likely it is the parking brake switch stuck or the wiring to it is damaged. If you move the switch by hand will it stop? Do you have a tool for testing electrical so we can do some tests? #1 · Aug 18, 2015 (Edited) I have a '13 825i, I couldn't find where this had been covered previously, but my parking brake warning is now beeping continuously. In the normal state, it only beeps if you try to put the machine in gear when the parking brake is set. Any ideas how to start chasing this one down?

Parking brake light won't go off: In this video, I troubleshoot and identify the cause of a parking brake light that stays on on a 2003 - 2007 Honda Accord 2 -parking brake indicator light still won't go off -realized that if I push on the air recirculation button (next to the AC button) the parking brake warning and light goes off instantly. -also realized that I am not getting cold air with the AC on now either. Parking brake "engaged" light won't turn off I spent the last 3 days working on the interior of my 2013 SCrew XLT 4x4. I had the negative battery terminal disconnected the whole time, with the exception of reconnecting to move the electric driver's seat to get to all the bolts once to remove the seat and again to reinstall. I'm thinking of just taking everything off the wheel, cleaning it all and plugging it all back in but does anyone else have anything else to suggest while I'm there ? I've noticed I can get the parking brake sensor box for about £40 but not even sure where this is let alone if it'll do the trick. Temporary Fix Pull over and set the transmission in Park. Please turn off the ignition, then turn it back on. Pull the parking brake switch and keep it for 10 seconds, then release it. Start the engine, and the light, in most cases, will turn off.
