Denial is not just a river in Egypt LB. Even though it was probably 10 plus years ago, you roundly rejected my dual VW ownership heartily. Volvo and Subaru you appear more accepting of.

Heheheheh.

Not all those who wander are lost;
The old that is strong does not wither,

I had a 1997 Cabrio for a decade and it was awesome.  Unloaded it when we had a 2d kid and it's practicality expired.

A 2D kid.....? Couldn't afford the third dimension?  ;D

All this really makes me want to do is by a VW diesel.

Volkswagen Scandal: Why Is It So Hard to Make Clean Diesel Cars?

http://www.livescience.com/52284-volkswagen-scandal-clean-diesel-challenges.html


Cleaning NOx from diesel fuel is also a challenging process. Because of the fuel's more varied composition and the engine's use of spontaneous combustion, it's not clear exactly when and exactly which compounds have formed, making it trickier to clean up, Hillebrand said.

About a decade ago, before emissions standards were lowered, car companies pursued different strategies for solving this problem.

"Different manufacturers made bets on different technology," Herner said.

Cars built by Mercedes-Benz, for instance, inject an extra fluid called urea to convert NOx into less harmful substances. This approach (called Bluetec) doesn't compromise on fuel economy or power, but it requires a separate tank for the urea, which must be periodically refilled, Herner said.

Volkswagen invested millions to develop a NOx trap instead. The trap soaks up nitrous oxide and nitrogen dioxide like a sponge. Once the trap is full, the system can inject a dose of fuel before releasing exhaust substances. The fuel reacts with the NOx to form benign substances, Herner said. Typically, the filter only runs for about 10 seconds, once every 10 minutes, Herner said. (They may also run their combustion differently at certain points to lower emissions.)

In light of recent revelations, however, it looks like Volkswagen made the wrong bet.

Volkswagen may have resorted to cheating because the NOx trap eats up fuel or reduces the car's pep, Herner said. It's a relatively simple fix to reactivate NOx traps on the recalled cars, he said.

"These vehicles can operate within our regulations," Herner said. "Our priority now is to get them fixed so that they do so."

But Volkswagen owners may end up being disappointed with the more sluggish, gas-guzzling cars they get back, Herner said.

Why, instead of relying on computers, can't the tests be directly on the actual exhaust? The answer? Laziness.

I think they did test the actual exhaust, but those are the standard laboratory tests, and VW's system was designed to 'pass' the emissions test in the lab, but switch off when put through 'real world condition' driving.  I think in Europe by 2017 it will be mandatory for automakers to pass emissions testing on the road as well as in the lab.  I remember reading somewhere Caterpillar and Volvo got caught with this type of cheating several years ago.

VW stock is at $107, buy now.

brand 'Made in Germany' hurt...

Gents,  what wussy would actually base his purchase decision to buy a "Königstieger" based of its NOx emission or a little higher fuel consumption numbers ;-)   



its all about the quality in the field  O0


and by the way:
did you know this magic abBlue is nothing else then a technical cleaned version of 10 times concentrat urine.
(its just water with 35% pure urea, while your urine has 3-4 % urea, well and some 'additives')
