I was surprised by this what you posted. However, I still have to insist that nowhere in any documentation of the Q7/Q8 models have I seen even a word about BSG as supporting ICE. Even in couple of these car tests it was mentioned that this is a specific MHEV without ICE electric support.
Especially that in SQ8 where there is a capacitor, it is also technically rather unlikely. The ICE booster, like the electric compressor in the TDI, requires a continuous power supply which cannot be provided by a capacitor. The capacitor is enough to pulse power the starter or the roll stabilisation system, but it is not able to provide a stable current for a longer time.

Went to dealer sometime in January. The SA said they are getting all the parts they need now. Audi Indianapolis said they no longer have a backlog of cars waiting on parts. Parts are coming in within a week of being ordered now.

A supercapacitor is not a capacitor as an electronic component. A supercapacitor is the same battery, usually made using LiFePo4 technology, it just has such a marketing name SCAP. Yes, it has less capacity than the larger lithium-ion battery, but it's still a LiFePo4 battery, which has very similar characteristics to lithium-ion.
Butt to supply the electric compressors in TDI or even to support ICE for a long time there is still a need of battery which will last a long time at constant voltage.

Dealers have started putting allocations on their websites instead of actual vehicles. At least, they definitely have been doing that in the Chicago area.
