Audi and Porsche are exploring the implementation of Android Automotive OS in their cars. Audi commenced this with the Q6 e-Tron and is extending it to the rest of their vehicle lineup. It's important to note that only new cars will come equipped with Android Automotive OS, and there won't be an update available from obsoleted systems to AAOS.
The existing Audi Q4 vehicles are based on MEB and, as far as I know, are identical to the VW ID, Skoda Enyaq and Cupra Born. Only Audi etron has other components.
At the beginning of the year I contacted the new CEO of Cariad, he is happy with pre-heating and wrote to me that he is checking what ME3.x looks like.
