^^^^ Zenerdiode: With the deepest respect, I don't believe that the good Burghers at VAG HQ treat their EU minions differently to buyers in other countries! My understanding from reading lots of forums is that the same value-set that you observed locally is universally applied world-wide (certainly it's the same dynamic down here in VW/Audi's puny little market in Australia). In a perverse way VAG HQ's world-wide (glacial) speed in responding to these matters is a good thing because it's non-discriminatory (as I said, perversely)!!
So, the real question is why is this happening? My hypothesis (which is based on nothing more than my analogy of VAG HQ to a dinosaur) is that the company is now so big and so successful that it hasn't yet linked the smoke that it sees to the fact that its feet are on fire! Sales are still reasonable world-wide that even a problem as important as the emissions scandal was treated as a niggling pesky insect buzzing around the Monolith's cranium - and this problem had the advantage of providing a convenient excuse to get rid-of an otherwise entrenched CEO!
Moral of the story: As Bernoulli observed in his second law of thermodynamics - the bigger the company, the more "commercial entropy" is acquired by the business as the complexity of day-to-day operations increases. The natural consequence is that is that the ability of the business to react to evolving market issues becomes more sluggish because of need to move a larger commercial momentum! And as Bernoulli's formula predicts, the larger the complexity of a machine (read commercial entity), the more prone it is to fail!!
So- perhaps your observations regarding VAG's behaviour (which I have also observed) is just the natural order of things!!
