The VW Group cars all come with software that tweaks "intelligently" based on whether they're being run on a dyno, or whether they're on the road driven by owners.

The steering angle sensors feed the ECU about the position of the tyres, whether they're dead on straight, or left or right and the degree of turn as well. In a dyno there is very little possibility of a turn, hence the VW engineers had tuned the angle sensors to consider anything from zero (straight) to 15 degrees as a "dyno" mode, ie the engine will become conservative, it'll drop the power and decrease emissions.. the ECU will understand it with a combination of rising revs with gear changes and steering angle.

On the road where there will be twists and turns, the ECU will understand that the car is driven normally by an individual and that it doesn't have a stick up its tail pipe, and so it'll enable 100% performance, and highest possible emissions.

All hail software coding, the new greatest enemy of mankind.

"Audi exhale around twice the permitted limit of nitrogen oxides in real world conditions when the steering is turned more than 15 degrees"

Usually the type approval or COP (conformity of Production) tests are conducted at chassis dynamometer. So there is no need of steering usage except follow the designated driving cycle displayed in the screen.

This way a software program easily can sense whether vehicle is been used for testing or not. However going forward this will not be possible as most of the countries implementing RDE (Real Driving Emissions)

It isn't. It is one of the clues that tells the software whether the car is on a road or a testbed.

Ahem, Pedants'R'us: I suppose it is, in that that it is harder work for the engine to drive a car around curves that on the straight. But that wasn't the question

VW and FIAT may not have a tie up yet, but both have been allegedly using the same fraud system to evade diesel emissions standards for years.

Now Bosch is in trouble?

Bosch software enabled emissions cheating by VW, FCA.

strong evidence that both defeat devices were created by Bosch and then enabled by Volkswagen and Fiat for their respective vehicles

Technical documents also indicate Bosch code was used in a so-called defeat device for a Fiat Chrysler Automobiles model, according to a year-long study by researchers at the University of California, San Diego and Ruhr-Universitat Bochum in Germany. That software set one mode for when a vehicle is being tested -- but then allowed tailpipe pollution to spike in real-world driving conditions.

Fiat Chrysler diesels spew excess pollution, VW sleuths report.

Fiat Chrysler diesel vehicles spewed pollution as much as 20 times the legal limit, according to testing by the same researchers who first recorded the excess emissions in Volkswagen AG’s diesel cheating scandal

The revelation from a West Virginia University laboratory sheds new light on the U.S. Justice Department’s allegations in a civil lawsuit last month that Fiat Chrysler Automobiles has used illegal "defeat devices," software that helps evade emissions tests. It comes amid growing concerns about the ability of diesel engines to satisfy U.S. emissions limits and the extent to which automakers may be working to navigate around them

Volkswagen to buy back Dieselgate-affected cars in two German towns.

VW waives its appeal in cases in courts in Arnsberg and Bayreuth, so will compensate owners’ affected cars.It will maintain this stance and has penned the cases as exceptions due to the low values of the implicated cars, and does not expect it to be the start of a domino-effect of buybacks across Europe

VW emissions scandal: Dieselgate fix is causing breakdowns!

Volkswagen emissions fix as 87% experience problems and some cars reported to go into limp mode, resulting in dangerous accidents.

Owners have also complained of reduced engine performance and poorer fuel economy following the fix.

VW owners complaining their car had gone into 'limp mode' - where the car rapidly decelerates to low speeds of around 20mph - after having the voluntary recall carried out. A mother who recently had the fix carried out was driving with her son on board her VW Passat when the car went into limp mode. As she tried to manoeuvre the car off the road it was hit by a lorry. Both escaped unharmed

87 per cent of the 542 owners who had the fix carried out experienced mechanical problems – 66.9 per cent with EGR problems, and 14 per cent with DPF issues. Data shows EGR failure has been most common on vehicles with more than 40,000 miles on the clock, with repairs costing an average of £800. A forum spokesman said: “We cannot simply stand by and allow VW’s fix to be further rolled out to an uninformed public.

After the SW update during his road trip he experienced sudden loss of power with MIL. Every time it happened he restarted the car and error went off. He had done like this for more than 20 times during the trip. After initial error, he checked the car in Skoda service centre in Scotland and they informed that there is some issue in EGR and DPF after ECU scan.

After coming back to Germany he went to Skoda service centre, he explained the situation. But Skoda guys informed him that he has to pay €150 for ECU scan and problem analysis and further for part replacements if required. He disagreed with it and told Skoda should resolve the issue at their cost since it came up only after SW update but service centre said since the car is old and ran more kms Skoda won't bear the cost. He didn't proceed and now waiting for filing case against Skoda. Until now his car is running without any other issues and he is still driving with his original clutch plates.

It's always difficult to prove such a correlation. Seeing some issues on an older car isn't unusual especially as relatively small things can cause these sort of issues. If your friend is ever in the Neigbourhood of The Hague in the Netherlands I lol happily hook him up to my OBD scanner.

Going to court over this in Germany is pointless in my opinion, but don't take my word for it.
Good luck.

More skeletons are tumbling out the #dieselgate closet. Here is one of cartelization and collusion. This is a big deal (in ranking of malpractices) in US, let's see how it plays out.

https://www.forbes.com/sites/bertels.../#31899c157ce8

Forbes just did a follow-up report that the rank and file is "rebelling"....

https://www.forbes.com/sites/bertels.../#5b5908aa45f6

It reflects a certain corporate culture- and will give fodder for management gurus for a whole generation to come...and make sound the death-knell for diesels in many markets.

Things might get worse for VW. German Chancellor Merkel has come out in support of changing German law to allow class action suits against VW for DieselGate.

I find this (from the above news) very interesting:

Many of the senior executives reportedly involved in the scandal are German citizens and out of the reach of American justice. It was Schmidt’s decision to travel to the United States from his native Germany that allowed for his arrest.

Why did he travel to US with family!!!

It's quite obvious that he's the fall guy, went with the management script because he didn't have much of a choice.
I'm personally OK with VW executives not being within reach of American law enforcement, given that same protection is available to American citizens, a crook like Warren Anderson got away scot free and so did the company. Dieselgate is nowhere on that scale. Outside the hysteria, what is the damage from the emissions, the US has pulled out of the Paris treaty, so safe to assume pollution is not a big concern for them.

Fiat Chrysler in talks over potential diesel emissions settlement.

In May, the Justice Department sued Fiat Chrysler, accusing the company of illegally using software that led to excess emissions in nearly 104,000 U.S. diesel vehicles sold since 2014. Numerous suits have been filed by vehicle owners.

Lawyers for Fiat Chrysler Automobiles NV and owners of the automaker's diesel-powered vehicles are in settlement talks over allegations of excess diesel emissions

Regulators have said Fiat Chrysler diesel vehicles had undisclosed emissions controls that allowed vehicles to emit excess pollution during normal driving.

The company has denied wrongdoing, saying there was never an attempt to create software to cheat emissions rules.
