New info on how VW, Porsche, Audi V6 TDI engine cheat works

The German newspaper Bild am Sonntag is reporting that US investigators have found three pieces of software that work in concert to turn off the emissions control equipment in certain diesel models after a set period of time. The engine in question, the 3.0-liter TDI turbodiesel, was found in certain Volkswagen Touareg, Audi Q7, and Porsche Cayenne models – the sale of which was suspended in the US late last year. Since most emissions compliance testing takes around 20 minutes, the software in the three VW Group models shuts off the emissions control equipment after 22 minutes, a straightforward end run around the testing. Remember that the 3.0-liter TDI engines aren't included in the big buyback and recall program announced for the smaller 2.0-liter, four-cylinder TDI engines. The 3.0-liter engines will likely get their own program, but we don't know when to expect it or exactly what it will look like. Last month, California rejected a proposed fix for the larger TDI engines, and VW went back to the drawing board. Since the company is unlikely to create two fixes, one for California and one for the rest of the nation, the company can't really proceed until they figure out a solution California will accept. The EPA hasn't officially commented on the report, and we don't know how Bild am Sonntag came across the information, but we'll be closely watching what emerges after this report. Related Video:

Both BMW and Audi shutter vehicle subscription programs

Both BMW and Audi are either cancelling or pausing their respective vehicle subscription programs, Automotive News reports. This is yet another blow to what was once a growing and burgeoning group of automakers introducing pay-as-you-go vehicle subscription options in a number of cities across the U.S. Both Mercedes-Benz and Ford shut down their services last year, and Cadillac turned off the tap in 2018. BMW’s program — Access by BMW — was only ever offered in the Nashville area. A BMW spokesperson explained the companyÂ’s decision making to Automotive News. "Our intent with the pilot was to learn about the viability of the subscription model and gauge customer interest. We are in the process of developing the next iteration of the program,” he said. When that next iteration will arrive is still uncertain. Audi doesnÂ’t claim that a comeback is on the way. Instead, the companyÂ’s website simply says its services are ending on January 31 this year. Audi limited its subscription service to the Texas area throughout its whole campaign. CadillacÂ’s subscription service was promised a reboot a long time ago, and today is the first time weÂ’ve heard some rumbling. ANÂ’s report claims that Cadillac is testing a rebooted version of the service in a dealer pilot now. WeÂ’ve reached out to Cadillac to see if it can provide any further details. As of today, the official Book by Cadillac website says Cadillac “will be debuting a new program in early 2020.” ItÂ’s now early 2021, so Cadillac is officially a year late on its announcement. A number of OEM-run vehicle subscription services still exist (Porsche, Volvo, Lexus, Nissan), but instead of the market expanding, itÂ’s shrinking these days.

2014 Audi Q5 TDI

I've struggled with diesel technology. It's not that I have a problem with it or dislike it, but rather that I don't particularly understand what stops its wider-spread adoption. Sure, memories of rust-prone, smoky, sluggish and uneconomical Oldsmobile diesels aren't exactly easy to erase from the collective memory of the North American motoring public, but I'd think that a few years into the latest crop of clean diesels, there'd be wider adoption - or at least consumer consideration - by now.
Part of the issue is the still limited number of segments that diesels are available in. The Volkswagen Golf/Jetta TDI is finally getting a challenger in the form of the Chevrolet Cruze Diesel, and the BMW 328d is bringing something new to the entry-level sports sedan, but there are still a huge group of segments where diesel-power has no representation.
The small, luxury crossover realm is not one of those. It has the Mercedes-Benz GLK250 Bluetec, a stylish crossover with a silky-smooth 2.1-liter, turbodiesel four-cylinder that can return the kind of fuel economy that makes people take notice. And while the GLK250 is quite good, economy will only spread the diesel's appeal so far. People need to experience the seat-flattening torque that these mills can produce, and for that, we most humbly recommend the new 2014 Audi Q5 TDI.
