I'm back!
And... since there are few other interesting threads, I thought I'd come back here.

So...so far we have proved that sensors can`t be depended on, Audi definitely has been known to have oil sludge buildup problems, aftermarket producers have a smile a mile wide and some car makers are trying to go the route of big government to the point of nannyism and some are falling for it, but most of all common sense reigns once again even though not adaptable to some people. Anything else? 
No, what we have so far, as part of the evidence you have presented as "well documented fact" is a clutch of stubborn Audi drivers who thought they knew better than Audi which oil was right for their car, and who, in their quest to save a couple of bucks, voided their Audi warranties by going to cheap oil change places, used the wrong (ie cheap, non-synthetic) oil, very possibly the wrong filter, screwed their engines at around 36K as a result, and who are now crying in their beer because Audi has washed its hands of them and is refusing to compensate them.
