2011 Panamera4 Engine check etc
Check engine&PDK&PSM etc faults light up on dash, and Pana goes into limp mode. Happened a week ago 100ft from the garage, I restarted and it went away. Then again faults in this morning, so I reset all with Durametric, one good 10mile trip in the afternoon, then all faults on the way home later (limply). Attached Durametric scan. 80K miles, code updated mid-2016, Porsche plugs at 50K, brake pedal sensor at 64K, new Bosch AGM battery September, but otherwise original parts. Any thoughts on what to try, or just take to mechanic?

Perfect, new coils fixed it.
Plugs and coils replaced with factory. Thanks much for your superb input. Around two months before any faults, I noticed a little vibration at idle, thought "It's just getting older". After the plugs/coils, it is smooth-as-new at idle.
I took a couple DIY pictures and notes if I do plugs again.
1. Squeeze towels in under plugs to catch dropped screws and tools.
2. Spark plug socket with short extender and set screws/dimples. Tie a string to pull it off the rear 2 plugs. 22ft-lbs on plugs. 45ft-lbs on motor mount.
3. Side ratchet with T30 torx for cover.
4. 10mm can do jack screws, and be VERY careful on jack screw torque at 5ft-lbs
5. To move on passenger side: blue and green wires, detach 2 vacuum hoses, raise motor brace. Driver side: unclip connectors out of bracket, remove the screw from the 12v cable holder.

When you changed your coils and plugs, did it resolve the error message you listed above, "B0300: Transmission Mount Valve -1-/-2- -N262-/-N263- Short circuit to B+ Value below lower limit value"

I think that error is not related to the plugs. Comes from PDK, I dont know exactly why it is coming, but guessing, maybe the valve body electrical connections or something related.
If anyone on here knows what this error means, will be great to have you chime in. Thanks.
As side note, when one gets spark plug/coil errors, especially in sport/sport+ modes, it triggers a series of other errors because car expects certain level of checks complete. One goes south, a series of other errors are flagged because the mode gets disabled, limps, etc, etc, to try protect engine from breaking, as car assumes something bad going on (assumes worst cases).
