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:

2015 Volkswagen Touareg TDI Quick Spin [w/video]

There are two particularly great things about diesel-powered cars: torque and range. The 2015 Volkswagen Touareg TDI has both in spades. We put 190 miles on our test car, and upon return, the computer claimed we still had 490 miles to go. We weren't even averaging the EPA-estimaged 29 miles per gallon highway. Plus, that's in a sport-utility vehicle with tons of room and a whopping 406 pound-feet of torque. That said, our most recent adventure with the Touareg wasn't totally positive. This thing feels decidedly long in the tooth, despite a 2014 refresh. Driving Notes The Touareg TDI's powertrain really is the star of the show. The 3.0-liter, turbodiesel V6 has been in service since 2009, but it's still a dynamite engine. With 240 horsepower and 406 pound-feet of torque, the latter of which can be called upon at just 2,000 rpm, there's no shortage of thrust under your right foot. Turbo lag is an issue when you get aggressive with the throttle, but don't drive like a boob and you'll be fine. ZF's critically acclaimed eight-speed automatic delivers that power to all four wheels. But where other ZF-equipped vehicles deliver a crisper, sharper character, the TDI's trans is tuned for a far more relaxed driving experience. Upshifts are leisurely; the eight-speed keeps you right in the thick of the Touareg's broad torque curve. The suspension tuning follows a similar philosophy. It's far more comfortable than dynamic, soaking up all manner of bumps and general imperfections with aplomb. That said, the Touareg does not feel floaty or disconnected – just smooth. The greasy bits of the Touareg are very desirable, but the package they're wrapped in is less so. It's not that the interior or exterior designs are necessarily bad – fans of Earth tones will love our tester's Black Oak Brown Metallic paint and Cornsilk Beige interior – they're just kind of bland, or anonymous. The switchgear and buttons come from the Volkswagen parts bin, and while they're fine on a $20,000 Golf, these pieces aren't as appropriate in a vehicle that starts at more than twice the price. The dash plastics and faux wood don't look as nice as what's inside an Acura MDX, or even a Jeep Grand Cherokee. This mid-level Touareg TDI Lux starts at $57,580.

VW announces recall of 26,000 2014 models with 1.8T engines

Volkswagen has followed up on a stop-sale order from earlier this month, announcing a voluntarily recall of 26,400 vehicles that are powered by the brand's 1.8-liter, turbocharged four-cylinder engine. The new mill replaced the despised 2.5-liter five-cylinder in the Jetta, Passat, Beetle and Beetle Convertible last year. Weirdly, though, of the 26,452 units covered in the recall, only 1,655 are customer vehicles.
According to VW, the affected models were built between February 1 and April 6 of this year, and feature bad O-ring seals in the transmission oil cooler. Apparently, the faulty O-rings could cause a fluid leak, as they won't seal between the oil cooler and transmission. VW is blaming a material change from a supplier for the problem.
There have been no fires, injuries, accidents or fatalities relating to this issue, which VW will be fixing free of charge. Customers will need to report to dealers to have the O-rings replaced.
