Air polution kills people... just saying
If I had a VW Diesel, I would not take it in for a fix. Running just fine, thanks...
Modern diesels have EGR valves that pass air from the inlet side of the turbo to the Exhaust to helb burn NOxs .
The TDI forum I used to belong to figures no big deal, no one wants to dump their cars, no one wants to shoot VW. Very happy campers.
Hmmm, I wonder why he had a smily face after his question
Very astute Kenttkt! It was in fact a tongue in cheek question...late night humour!
So the regulations required the nox to be at a super low rate to fight GLOBAL WARMING. To get the cars to this nox level would have required more expensive hardware or less power and fuel economy.The EPA is fat and lazy (and stupid) to let this happen for so many years.I am trying to figure out when these super low nox standards came into being.

http://www3.epa.gov/cleandiesel/reg-prog.htmLooks like new rules and standards were starting to phase in as early as 2006 on the fuel side of things. I thought I read 2007 or 2009 when the new automotive standards were phased in from the emissions levels standpoint.I believe the EU is also pursuing similar tighter standards, including tighter regulations on NOx, but maybe not as tight as US currently.
Seems a bit odd (or maybe they just have better PR than we do) that the Europeans, the champions of Kyoto Protocols, who are getting rid of their nuclear plants, who are more sensitive than us dirty US cowboys about Global Climate Change .... should have looser requirements than the US on NOx emissions for cars? They have so many neat little high-mileage diesels that I'd love to have, but they never seem to be able to meet US standards?Just seems the opposite from what we "hear" .....Lannis
I THINK they are tightening them up. You gotta pour through the standards to try and compare apples-to-apples:https://www.dieselnet.com/standards/
Good info. The surprise, then, would be that the USA would ahead of them on emissions requirements .... that's not the rap we normally hear ....Lannis
As an aside. IIRC back in the 80s some cars had a connection from the inlet manifold direct to the exhaust via a valve that opened at idle (test revs) with the sole aim of adding additional air to the exhaust thus diluting the % if pollutants coming from the tail pipe.Did I dream that??

Don't forget Rule #1 - If YOU'RE joking, then I'M joking. If YOU'RE NOT joking, then neither am I.That way you get to decide if it's "serious" or not .... Lannis
I'm sure it's a $$$ issue.Installing DEF systems for the USA cars would've been more expensive than what the software "test mode" programming cost to develop and implement.And maybe, they felt that buyers would resist cars with DEF.Not that big a deal, really. Big diesels are running DEF in The USA, and DEF is available at many gas stations which sell diesel fuel.
And maybe, they felt that buyers would resist cars with DEF.
In retrospect I had noticed with the roll out of the VW diesels that their system lacked the DEF. Frankly, that was enough to INTEREST me where it was the straw the broke the camel's back for most other manufacturers and I wasn't really looking to deal with that.It wouldn't surprise me AT ALL if it was a part of their success in the segment.
Absolutely! Look at the other diesel passenger vehicle options in the US. Mercedes and BMW. Both are in much higher profit margin segments. An additional $1,000-$1,500 in cost to the diesel option dissuade the buyer of a vehicle with a base price in the high teens to low twenties than the buyer of a $40K + car.
I wouldn't be surprised if the owners of these cars will face a mandatory recall. Probably will need to have proof of EPA certification at time of tag renewal or sale. A "scarlet letter" sticker attached to the engine and title.
Diesel vehicles are a significant presence on Europe's roads - with Europe accounting for three quarters of 2014's diesel car sales. They emit more toxic particles than their petrol counterparts, leading to concern over their threat to human and environmental health. Air pollution is estimated to cause 30,000 deaths each year in Britain. A toxic gas called nitrous oxide is partly to blame, which causes smog, respiratory illness and heart and lung disease.
Dodge Ram's and Jeep Grand Cherokees have diesel options that can cost up to $5k with the required additional "packages".And that's on something that was probably already north of $40k on the trim level before you started.We thought about a diesel GC (it wasn't out yet, but knew it was coming). But the ROI wasn't there in the mpg, not to mention the DEF hassle and other differences in operation.The only way it would have made sense was if we were towing heavy loads often.
