What's to understand? Their engineers weren't good enough to make it work.

I think you got it wrong. It would have costed much more and they had to stay within a certain cost frame. To achieve the goal(s), better and/or additional hardware was required and this would have made cars more expensive by a couple of hundreds of EUR (production cost!).

Another problem was with Diesel cars using aqueous urea solution. Usually, that urea solution needed to be refilled after 10000-15000 km, which was OK. Now, after the software updates, often every 5000-7000 km. Smiley

Meaning: They tricked with the software to achieve a lower urea solution consumption. Why? Because customers wouldn't have really bought cars which require an Ad-Blue (urea solution) refill every 5000-7000 km. I even heard of some cars which require the refill every 3000-4000 km, which is insane. Keep in mind that after the Ad-Blue reservoir is empty (you get various warnings before that happens), you cannot start the engine anymore. Smiley

Was that illegal? Of course but this had nothing to do with skills but with cost and maybe greed. Smiley
