There are statistically proven negative points in being not very attractive in general. Beautiful people have (significantly) higher chance to become successful in their job and/or businesses.
So the disassembling confirms that ECU is just not feeding the exhaust with AdBlue/Urea. So what is the advantage for VW in all this?! It does not make your car more powerful, it makes it less eco-friendly, you are just saving money on AdBlue/Urea.
