I think this is part of the problem. The EA189 without AdBlue needed the cheating software. The Passats with AdBlue also had the EA189 and likely could have been tuned to work without the cheating software, but likely have it anyway.<p>It&#x27;s a bit of a shame that EA288 cars are stacking up at dealers nationwide and will apparently never be certified for sale (VW said they would not ask for certification), even though they almost certainly don&#x27;t need the cheat. (Although it&#x27;s possible that it&#x27;s still present, which is of course still illegal, need it or not).
