-12 Panamera PDK issues

Hey all! Long time reader, first time poster

So something weird happened to my Panamera over night.
I haven't had any tranny problems what so ever before. Though today when I was going out. It just did not want to drive.
When I move the shifter I feel it engaging the gears, and it kind of rocks when I go from D to R and let off the brakes. If I put it in R, it will reverse an inch or so. Same when I put it in D. But it's not like I can jerk it forward. It's pretty much stuck where it's parked, if you understand what I mean.
I tried putting it in N and push it. But it won't roll either. Almost like it engages the gears, but is always stuck in park.

The strange thing is that I drove it and parked it fine yesterday. No noise, no jerking, nothing weird at all...
E brake was off. Turned it on and off several times as well. Still nothing.

Checked under the vehicle for any leaks of trans fluid, but did not see anything. Though I'm in FL so it could have dried up...

Anyone have any clue as to what it could be?? One of my folding mirrors went nuts yesterday going out of alignment by itself. But then fixed itself after I manually moved the mirror a couple of times. Can it be the ECU acting up or is it the PDK??

Thanks for now!!

How's your battery? I'm hearing that strange things happens with this car when the battery starts to go bad. Just doesn't have that proper oopmh from the battery causing all types of electrical issues, including the PDK.

Thanks for the reply! Interesting theory indeed
It's reading steady at around 14.2 volts. Never any problems starting it up. Though lately lights and screens have dimmed down a bit while the starter motor is cranking

Update.
So I had a Porsche mechanic come to check the car out.
He connected the reader, but did not get any error codes for the PDK system.
He told me he suspects the clutches are worn out, but won't know for sure until they take it to the shop and takes it apart. That's all he said...
From what I've read. The PDK clutches does not wear out easily. And I only have 70k miles on it!! I also have the base 3.6 without Chrono, so I can't even launch control.
This is my daily driver so I'm not driving it hard or punish it even a little.
What do you guys think about his opinion??
And as I said in my OP. I have never felt any jerking between gears or clutch slipping before.... Sigh...

I'm fairly new with this car and had for only a few months, just trying to make sense of it.

But do do you have ParkAssist? I noticed mine when i'm parking it in the garage where it's very close to objects and the wall, it would feel like it would slip, hesitant to advance forward, and beeping like crazy, unless i really give it some more gas...and then it would jolt forward all of sudden. I could've sworn the side mirrors moved also, thinking it wants me to see objects on the ground or something.

Have them check that maybe, and still...the battery. Even if you're still getting 14.2 volts. Also another thing to try is the PDK reset procedure. Apparently it learns your driving habits...kinda creepy-stalker-like way. . ...and another, you're about due for transmission fluid change I believe.

Thanks for the reply bud!
I'm not parked close to anything. But will try to disable the parkassist just in case.
How do you do the PDK reset procedure??

Having a battery guy coming over to check it out in a few hours.
At this point I'm willing to try anything before taking it to the shop and pay thousands just to do work that possibly might won't be the cause.
Like I said... Never any slipping or strange shifting behavior... Tranny fluid might be a cause as well. But shouldn't I felt something?? The whole "worked fine on day, then not on the next" thing is mind boggling

Yeah good luck, i'm curious to know what it may be. Keep us posted.

Also, on the left battery terminal should be numbers stamped on the post. First number is the year, and the second number is the week of that year.

Here you go...

are you primarily driving int the city? i.e. lots of stop and go? it technically is a manual trans controlled be a computer, so lots of stop and go would probably put more wear and tear on it than a couple of launches.... or frequent highway miles.

Tried turning off the parkassist. Tried the PDK reset. Battery guy put in a new battery. Still nothing.
Hopefully I'll get it to the shop tomorrow...

Put a trickle charger on it overnight. It does sound like the ebrake is on, even though it’s not lit. I would also try the PDK reset procedure (search this forum for it) to make sure it’s not the PDK.

another option is to disconnect the battery for a while, you will lose all, your settings but there are so many sensors and computers sometimes they just need a “reboot”

Good luck

Did the PDK reset.
E brake engages and disengages perfectly. The car won’t move. Even if pushed. Just wags back and forth.
The battery guy drained the electrical system. Still nothing.

Perfect description of the issue is: Stuck in park. While being able to engage gears

Get it towed to a dealer and flush the PDK fluids, or do it yourself.

i was shocked at how many issues went away with just changing my fluid
