From my understanding if the engine code is the same the software is basically
if not exactly the same (excluding SW revision which mainly depends on build
date), at least not much different. For example in CNRB 'B' is engine SW version
including power level. If two engines are different they must come with different
last letter. CNR specifies hardware only.
Of course I could be wrong, but that's the principle I was told by all VW or Audi
engineers I met last 20 years.
Did I mention this engine deserves a VW 507 00 approved oil? I'd use either M1
ESP 5W-30 or Ravenol VMP 5W-30. Using a VW 511 00 oil is a smart idea though
I don't think a 0W/5W-40 is even required. However if you feel better with thicker
oil just go for VW 511 00/Porsche C40 - no issues to be expected. Again either M1
or Ravenol (RUP).

Times have changed and so has the relationship internal brands amongst conglomerates.
Without diving too deeply as this point should be easy to address, why the 5k oil change for the Cayenne vice Q7/Touareg? Same oil, air filter, oil capacity, and fuel filter for three. I’m sure you have an explanation for that.
This isn’t a VW vs Porsche dealio. I respect other makes to an extent. Maybe everyone got the notion you could have 957 or 958 for half the cost…. I don’t know nor do I care.
