as i said vw just packing it in one hit executable programm as where others hide it more over the whole cycle and exploit the loop holes of what allowed in labor testing .

For many years examine the diagnostic experts of FCD Vehicles, which bring their owners - or also workshops - with particularly persistent disturbances to the edge to the despair. Many ten thousand measurements assistance of storage oscilloscopes, in addition, with classical diagnostic as well as exhaust testers already accomplished the team around head of the company Libor meat Hans and solved so also trickiest cases of repair. Here, in addition, in the context of decided exhaust investigations, FCD observed again and again ???anomalies ???. Things, which might not so at all be. Things, which actually forbid current exhaust laws. More exactly said: A partially completely covered nitrogen oxide output with modern Diesel passenger car.

???This is particularly very high if we drive economically, or if we demand, explain the achievement of the engine ???meat Hans. Differently expressed: ???Details then, if the engine achieves the actually optimal efficiency, are the NOx- Output most highly ???, so the expert. With this Handicap all vehicle manufacturers have to fight. In principle only the possibility remains for them of increasing either consumption or of reducing the achievement. Alternatively they must invest into an expensive SCR system with according to large urea supply (???Ad-Blue ???). Because different than with truck no place is present in a passenger car for a sufficiently large tank. So the Ad-Blue-tanks must fail with passenger car from view of the driver too small. Finally it must usually worry about the refueling between the service intervals. Recycling of exhaust gases over hours deactivates
???There for example those Ford Mondeo were 1.8 TDCi, year of construction 2010 (engine code QUYBA), we as one year's young used one the examined ???, remember meat Hans. Cologne models switched off ???simply so ???its recycling of exhaust gases sometimes over several hours. FCD had equipped the vehicle with a Datenlogger and had in such a way collected over a whole week relevant data in driving.

The Czech specialists stated that the AGR valve was times actively and times not active. The comment of the manufacturer: If an error in the error memory actual and that were not also not put down he, then the motor control is in the specified condition. A complaint was therefore rejected. ???A recycling of exhaust gases, which as a substantial component serves for the minimization of exhaust gases, simply switch off? A fact, which would be inconceivable in the context of an official exhaust test ???, commentates of meat Hans the phenomenon. Or that Peugeot 308 with SCR Kat, which revealed in the course of an exhaust test a completely different one ???to Ad-Blue-frequency ???than on the road. Several times the FCD team had tested the Frenchman on the Rollenprüfstand and in the road enterprise. It was noticeable that the vehicle accomplished the exhaust with absolute precision, necessary for the function of the SCR system, always fifteen seconds after engine start and it besides still three times repeated, as soon as it recognized ??????to run on laboratory conditions. In the road enterprise under same outside temperatures this ventilation happened only after about 400 seconds. Only then the system was ready for use. Only then the nitrogen oxides could be fought at all. The consequence: The car discharges so clearly more the toxic gases on the road than on the test stand.

reads quite horrible but you can still see what they wrote about others cheating just better hidden. they dont run a cheat in the lab they just run the cheats onroad. AGR=EGR

there is new emission rules for more relaistic figures comming and its 110 times higher then the emission rules of today.
Well as you probably know. Deisels clog up with that much crap through the egr and intake. As well as dpfs. Seen a dpf on a nissan that was that clogged full of crap the car had screaming gasses coming out the turbo. Just from driver ignorance. Engines will not simply be able to be 100 × cleaner emissions without some serious technological advances.

Volkswagen directly cheated, everyone else optimises for the test cycle
Pretty big distinction there

Iv seen manifolds and heads so restricted by EGR that only a path about the size of a dollar coin remains. New Tritons were bad for it.
How can we be advancing when we seam to be trying to put more and more crap back threw then engine?
Add blue is on it's way.

Thank goodness, another great reason to resist having a diesel. Burn refined products!
