Just took a look on Amazon and none of those $40 sensors fit the B9 S5. In addition to the 4 sensors, there is also the upfront cost of the receiver and the control unit.
I stopped drinking the BMW kool aid after my 2013 M3.Weight distribution plays a huge factor in dynamics. The newest version of the dynamic diff does a great job of hiding some of that understeer, but you can't defy physics.

The majority of Audi owners globally are unlikely to want a direct TPMS fitted as standard equipment. By example, it is mandatory to change tyres / wheels between the seasons in much of Europe - a region twice the size of North America in Audi volume terms. As an option, fine, and Audi is rolling this option out in new models. The option price is around $250, this will vary a little from model to model, market to market.

As Audi USA dealers do not like long option lists (because most of their customers prefer to buy off the lot rather than factory ordering), it is possible that the option will not be made available in your specific market. Or if Audi of America feel that the majority of customers would prefer it, include it as standard equipment. Just like they do with, say, a sunroof.

And in the case of RS vehicles, the primary advantage of the direct system is monitoring tyre temperatures. Not for knowing you have a puncture - the indirect system is more reliable for that function. Of course, there is the convenience factor. At a guess, I would say the majority of owners never check their tyre pressures. At least with the direct system, some of these owners might remember now and then to bring up the MMI screen and have a look. But even then, probably only a minority would. And then that assumes that owners know what tyre pressures they should be using. How often on these forums do we read about owners using the maximum load capacity pressures on their lightly loaded cars? Rhetorical question - often.

But yes, Audi spare parts pricing is high. This should not be news

I agree that you have to watch the details going forward. All the manufacturers are cost cutting / chasing margins to fund the development stage of EV.
The Sportback actually DOES have 60% of its weight over the front. Audi dealers don't want a long option list? GREAT! Make it standard. BMW and Mercedes both have it as standard equipment. If two rival manufacturers have the means to make it standard equipment, Audi has zero excuse.

Noticed the TPMS in my A5 does not indicate over pressure. The dealer in December said they adjusted the pressures to 35psi for the winter when I took the car for its first oil change. I was checking the cold tire pressures with my Accu-gauge gauge two days ago outside temp 68F all four was showing 42psi. Accu-gauge claims +/-2psi accuracy. Only thing I can think of is that they reset the pressure on the MMI.

Neither are 60% as you like to state.

except they weren't $20 or $30 as mentioned

I just replaced a set on my beater A4 - my cost was ~$100 each at my cost . Yes I could have gotten aftermarket ones for $69 each, but preferred the OEM ones, since they served me well for the first 10 years/154k miles. I don't need to tie our dealership shop up with my bs work on an aftermarket part that might have an issue being programmed, or might last me 6 months.

Take a look at myth # 4, some of the best handling race cars in the world has a 60/40 weight distribution. BMW like to advertise their 50/50 weight distribution because they speed so much time and effort into getting the car perfectly weighted 50/50. Recently, even BMW is starting to step away from that and some of their newer models are no long 50/50. Audi for years have been getting away with some pretty good numbers handling wise for a car that is front heavy. The rear bias AWD and the sport diff. definitely helps. The most recent Audi models are much better balance than the previous models.
