Audi recalling 70k TDI models worldwide over braking problem

Audi is issuing a recall covering some 70,000 vehicles worldwide, due to problems with their brake boosters. According to Automotive News Europe, diesel-powered examples of the A4, A5, A6, A7 and Q7 are all being called back due to this issue.
The report indicates that while the brakes in these vehicles still function, the enhancing power from the booster may fail due to a possible leaky membrane.
All of the affected vehicles are powered by the 3.0-liter TDI turbodiesel V6, and were built between March and December of 2012. It is unclear as of this writing how many of these vehicles are in the States, though remember, US customers are not privy to 3.0 TDI examples of the A4 or A5. Autoblog has reached out to Audi for specific numbers, and we'll update this space when we hear more.

Next-gen Audi S7 looking hot in Southern Europe

Development on the next-gen Audi S7 is in full swing. The handsome hatchback is still popular, even if it is starting to show its age, so we have high hopes for the new model. We have some new spy photos of the car performing hot-weather testing in Southern Europe. We don't have many details or a firm release date, but there are a few things we can pull from these pics. The new model looks like it will retain the same general shape as the current one. That's a good thing, as the A7 is one of the best looking vehicles on the market. The long and flowing roof, frameless doors, and long wheelbase all look to be present. There are hints of the Audi R8 from the A-pillar forward while the large grille looks exactly like the on new Audi A8. Many of these design elements are straight off of the Audi Prologue concept from a few years back. Like other Audi S models, the S7 has a wide bumper with large intakes at the bottom corners. A chin spoiler appears to channel air down under the car. Around the side, we can see big wheels and brakes. There are side skirts along the bottom. Out back, it has the requisite quad exhaust tip, a dead giveaway that this is an S model. Lighting both front and rear appears to be LED. What rests under the hood is arguably the car's biggest mystery. We can count on Quattro all-wheel drive and an eight-speed automatic, but we don't know if it will have a turbocharged V6 or V8 under the hood. At this point, both seem equally likely. Horsepower and torque should both be in the mid-400 range while 0-60 mph times should be around 4.5 seconds. Look for more news this fall.

CARB has 20 days to confirm VW's 3.0-liter TDI emission fix

VW's diesel scandal has been in the headlines since last September, but solving the problem it proving difficult. Volkswagen Group has submitted a proposal to the California Air Resources Board (CARB) and the Environmental Protection Agency (EPA) to fix about 85,000 vehicles with the 3.0-liter diesel V6 in the US, Reuters reports. CARB now has 20 business days to test if the plan actually reduces emissions. If accepted, VW could finally begin a recall and end the stop sale on vehicles with these engines. In a statement, CARB pledged to, "respond following a thorough and complete review to make sure the plan addresses the presence of the illegal defeat device and follows the necessary environmental, vehicle and public health and safety regulations." Neither CARB nor the EPA outlined the proposed repairs, but Porsche CEO Oliver Blume already suggested the fix for the engine in the diesel Cayenne. Examples from 2013 and 2014 allegedly need a new catalytic converter and software update, and those from 2015 and 2016 only need the improved code. It's not yet clear whether this procedure would work for all models with the 3.0 TDI. While the EPA issued the notice of violation against VW's 2.0-liter four-cylinder diesel in September, the first one for the 3.0-liter V6 came in early November. By the end of the month, the agency broadened the scope to about 85,000 vehicles, including some examples of the VW Touareg, Audi A6, A7, A8, Q5, Q7, and Porsche Cayenne. The affected companies issued stop sales on new models with the engine. Audi eventually admitted to regulators that it didn't disclose three auxiliary emission control devices in the powerplant's code and promised to develop a software update to fix the problem. CARB gave the automaker 45 business days to submit the proposed solution. If accepted, this repair would allow VW Group to end part of the emissions scandal, but there's no guarantee the regulators consent to this solution. Just a few weeks ago, CARB looked at the automaker's plan to fix the 2.0-liter TDI and rejected it, claiming a lack of detail.
