Help sell cars. I have a TDI sportswagon and this will be the second performance hit. A couple years after purchase there was a recall to reduce the power a bit via software "upgrade". Seems fuel filters were occasionally failing at high acceleration or with people that used high acceleration a lot. The power drop was minor but noticeable. I suspected then and even more after this indecent that VW knew about the problem but wanted max power to help sell cars during the test drives.
