First, all the codes you have listed are individual cylinder misfire events. Secondly, get a better scanner, preferably one that it is relevant to Porsche; P1317 is not a camshaft position related code in a Porsche, it is a misfire in cylinder 5, and 1319 is a general “emissions relevant misfire” code.

If you had a diagnostic system specific to the car, such as the Durametric system, a PST II, or the vaunted PIWIS system; you can read the camshaft position and trigger the VarioCam system in real time with the engine running, allowing you to eliminate them as a source of your issues. As much as I hate to say it, you probably replace a tensioner that may have been worn, but otherwise was fine. Before you replace the VarioCam unit, get the car checked on a proper diagnostic system and find out if it really needs replacement......

Smart phones are not always as smart as you think they are..............and in your case appears to be misleading you……..
