They don't test the software sufficiently on these cars. Reminds we of a bells and whistles Linksys router I had. Very good reputation got taken over by Belkin then they became rubbish. Crashed constantly. Firmware was rubbish, updated, still rubbish. Linksys tried to wiggle out of it... got my money back (moved to Asus they are great). At the time of the fake Amazon reviews where they gave out the stuff free for positive reviews. You could separate those reviews from the Amazon site. Everybody who bought them gave them the thumbs down, bought reviews with the free equipment, thumbs up. I did a chi-squared test of independence as I recall .
Think VAG are still suffering from dieselgate so have cut corners on QA. The infotainment system runs on the new Linux car system rather than QNX of Mib1 and Mib2. The rest of it is a new platform with new systems. Mib3 was tested on Passats for a year in 2019 so they should have picked up bugs. Either way poor management that don't have their eye on the ball. Just in time productions seems to mean ship them with bugs including the fixes with bugs .
