Speaking of tire pressures, I was surprised to see 38 front/32 rear on the door frame placard. Presumably engine weight front compensation. Of course the dealership had just inflated to 32 psi all 'round. Note to self - don't forget to reset the MMI limit when filling tires.

I always go by the placard. Just ol' school of me, and I'm from a fairly old school. 
But concur as similarly my allroad did have a normal (32 all 'round) and loaded (32 front/35 rear). Although its placard listed 32/35.

I hear ya, but now that the placard is full load, you'll be better to use the values listed in the owners manual. Will be a smoother ride, as rear tire pressure has a direct influence on ride quality. Plus it is what's correct for ideal tire wear.

True, but again the front wheels are what call for the higher pressure in the TT's case (38/32).
I tried it "loaded" yesterday, passenger and solo, and it was fine both interstate and secondary.
Preaching to the choir - quite correct however that there is an optimal pressure for ideal tire wear as well as performance, which relatively differs over the course of the season (e.g. same 32 psi instrumented setting but actually higher density air in northern Winter). So check those tires often.

Then why are the standard load pressures the same for the TT and TTS? I'm still trying to figure out why adding mass aft of the CG requires higher PSI in the front. Are we looking at a typo in the book and the placard?
Anyone have access to a European owner's manual to see what it says?
