The current scandal is only about the "EA189" engine family with NOx traps for exhaust treatment. The new "EA288" engine family with urea injection was designed from scratch, and, I hope, doesn't need cheating software.
Edit: the EA288 is/was -- at least in Europe -- also sold with NOx trap, but VW still claims it's free from cheating software.
- caskance 11y agoConsidering all we've learned in this saga about the industry in general and Volkswagen in particular, I would say it's more than likely that it had cheating software anyway.
- rconti 11y agoI 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. It'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't need the cheat. (Although it's possible that it's still present, which is of course still illegal, need it or not).
- kuschku 11y agoYes, completely different families. EA189 was a Pumpe-Düse system able to get up to 280mpg in production vehicles, at the cost of high NOx emissions. EA288 is a standard common-rail engine with AdBlue.
- arcticbull 11y agoThe 189 may be either Pumpe-Düse or Direct Injection. AFAIK all the post-2009 models implicated are common-rail direct injection.
