No evidence of GM, doing anything untoward re: diesels.Overzealous lawyers after more money after seeing the VW debacle?
The engine control is allowed to disable certain systems like cold air EGR until the engine is up to certain temp to avoid carbon buildup and premature cat failure. I'd guess this is what will make the basis of their case. The case is false, but that doesn't mean they won't win.Could be something like this: There are instances where diesels run and emit more emissions and pollution than they ordinarily would. For example, when headed up a steep hill under load. This is not a defeat device and it's OK so long as the manufacturer tells the EPA. I think this is the issue with MB BTW.
Great! I should be able to get a good deal on a Cruze diesel. Great engine/tranny combo (IMO). I think this is the coolest car motor GM makes.Clean coal, clean diesel, clean lead, clean plutonium. I think "clean diesel" has been tainted by VW for a long time to come.
There is a cat light off stage where the engine runs richer to get the cat up to temp.It's my understanding that the EPA allows emissions to go out of spec temporarily to protect the engine under extreme conditions. Two of the three offending scenarios (see link below) appear to fall in this category.
The third scenario is more worrysome. Here's what GM Inside News says:
"Far more nefariously, when the emissions system shuts off after 8 minutes of steady state driving the trucks will allegedly emit 4.5 times the legal limit."
Yes.Overzealous lawyers after more money after seeing the VW debacle?
It's not a "chip". You need to remove the pollution control devices and rewrite the programming in the PCM.well that's going to hit gm's bottom line
pretty sure the diesel pick up, had one of the highest profit margin for gm/dealers
what about the aftermarket diesel chips that let diesels spew black smoke out the exhaust, to the point of being called -rolling coal
If you read the some the article (many exist) lawsuit CLAIMS there is evidence...I'll cherry pick from the article, no need to thank me:Yes.
Real world conditions vary from standardized laboratory tests. Emissions being higher on the road is not a surprise. No doubt GM tuned their diesels specifically to meet testing requirements.
If the EPA had something on GM, we'd have heard by now. There's no evidence that GM broke the law like VW did by disabling emissions controls while on the road.
