Secondly, I have the P1341 error show up twice. The first time it happened was when my wife stalled the car to prevent running into someone in front of her. After clearing the code it popped back up (that's the second occurrence) while driving and a misfire occurred (actually the engine seemed like it just cut out for half a second). One of the interesting things I found was the cam adjustment is hydraulic. So, low oil pressure, cold weather, thicker oil, old oil, etc. can all possibly contribute to the CEL. I was just about due for an oil change, so changed it using Mobil 1 European blend and went for a spirited drive. No return of the CEL to date.
I can't say either of these suggestions will make a difference (MAF or Oil), but both are cheap and easy to check out. As another weird thought, isn't this the rebuilt engine after an IMS failure. If it is (my memory may not be correct) then this could also be one of those times when an IMS disintegration with all the floating pieces of debris that could clog oil ports may have bit you.

Hopefully, Porsche Center Oslo will figure this out. I got a price for $120 for a full scan and diagnosis. Hopefully they are smart enoguh to try and error such things as unplugging the MAF and so on.
But many many thanks for your support!
What brand was your MAF? I went for original Bosch and there are no error codes thrown that suggest bad MAF. I heard cheaper MAFs die quickly.
I did an oil change after the IMS upgrade, and the Porsche Specialist went for Castrol Edgen 0W 40
Castrol EDGE 0W-40 A3/B4 | Features and Recommended Engines | Castrol EDGE which supposedly is great for our cold winters.
We did check the oil filter two weeks after the IMS upgrade and there was not even a slight sign of any metal debris. And hopefully, there are none left in the system that could clog up the oil pump / ports etc..
