The old manual e-brakes do take room in the center console and I like it not being there, and I am one that has a lot of manuals over the years. And you have to admit it does look cleaner without it there.

Needless complexity with an electric e-brake, I always liked the console parking brakes for control on hilly roads, it's an involvement thing for me, don't expect it's for everyone.

Hi guys, I am new to Rennlist! Just got a 2014 Porsche Turbo S last week, I am absolutely in love with it. Bought it as a daily driver. I had it inspected at the Beaverton Porsche dealership, and it had no issues during inspection, but of course 2 days after receiving the car, this same exact fault parking brake error appears, the light on the parking brake is flashing and the actual brake is malfunctioning. Another issue is the map stays on "loading". I am not sure it's because I brought the car down from Oregon to Southern CA. I am taking it to the dealer on Monday morning, so I will keep you guys updated.
Also, sorry if this is obvious, but how do I start a new thread on the forums? Replying to an existing thread is pretty simple, but I don't see where I can start my own new thread. Thanks in advance.

Digging up this old thread to add my experience with the ‘Parking brake fault’ error message in the MFD along with the parking brake error light. My experience is with a 981S, but I imagine the 981 and 991 systems are very similar if not identical.
My car is a 6MT, and when parking the vehicle on a slight incline one day after a short drive, the message appeared in the MFD. Once it appeared, the parking brake could not be released with the lever (it stayed illuminated red). Multiple attempts of turning the car off and back on did not clear the error. The only way to release the parking brake was to fasten your seatbelt, put the car in 1st or Reverse, and attempt to drive away. The ‘intent to drive’ function auto releases the parking brake. I’m not sure how this would play out in a PDK car. Once the car was stopped and the engine shut off, the parking brake would auto apply and the error message pop back up.
I brought her in to a local Porsche specialist and they figured it out quick. Turns out the parking brake was out of adjustment which threw the error code. There is a drum brake shoe inside of the rear calipers and my thought is that it went out of adjustment over time due to use (car has 60K) and/or wear of the braking surface material. They calibrated it and the parking brake works better than ever now. Cost me 1 hour of labor plus a diagnostic fee, about $270 all together. It is worth noting that there is an audible difference in the sound (and thus speed) of the parking brake engagement now after the adjustment.
Another common cause of this fault that I discovered during my research is failure of the parking brake actuator. Mine was fine, but if the adjustment doesn’t work to clear this issue up for you, the next lowest hanging fruit would be this.
Hope this helps a 981/991 owner down the road that may run into this same fault in the MFD.

I was gonna suggest checking the parking brake shoes gap... After doing my brakes I noticed the rear Ebrake setup was like an old 356/911, i.e drums (the inside of the disc hat) and shoes. You can reset that electronically with any ODB reader tool after rotating the adjuster (cylinder with teeth) to get the shoes closer to the drum (could be worn) and see if that helps ? that'd be my step 1 because zero trip to dealer and zero expense. One screwdriver and one reset, worth a shot. You undo one lugnut/bolt (whatever we call these things), flash a light in the hole rotating the rear wheels until you see the teeth of the adjustrer... using a flat scrwdriver rotate 2-3 teeth on each side (no I don't know which direction) and see..

LOL indeed.. I guess in theory one could drill the new disc for an access hole but that seems silly give how rarely one checks parking brake adjustment.
All that means is if you wanted to, you'd have to remove the calipers out of the way and pull the disc to do that (easier that way anyway) and be out $20 of new caliper bolts... Maybe worth a dealer visit in that case - could be something else purely electronic.. Depends on your level of comfort... Still, LOL... studs ( I get it, more practical).
