4DR Turbo,
I believe that M1 0w-40 is one of the best PCMOs (OTS or not).
And, as long as your oil consumption is relatively low with this oil - for the benefit of your cat, rings, etc., I would use it.
Newer VW/Audi engines esp. with K03 turbos have narrower passages, higher oil flow rates, high temps, and benefit from 0w/5w wt. cold viscosity, 40 wt. (or 30 wt, if robust enough) hot viscosity, and 3.5 min HTHS oil. There is anecdotal evidence that suggests that one reason Audi K03 turbos are damaged is because of too thick cold oil, or too thin hot oil viscosity.
If you plan to change this oil every 8000km (5000m), I believe you will be fine without an UOA.
Hope I didn't offend anyone! Though, an UOA will tell if all is well with your engine.
