Audi follows suit with TDI stop-sale

Yesterday, Porsche issued a stop-sale on its Cayenne Diesel, following the news that the Volkswagen Group's 3.0-liter diesel V6 is also fitted with cheating software. Now, according to Automotive News, Audi is issuing a similar stop-sale in the US, but in the case of that brand, it affects more than just one model. Audi's stop-sale covers diesel-powered versions of the 2013-2015 Q7, as well as the 2014-2016 A6, A7, A8, and Q5. All of these models can be had with the 3.0-liter TDI V6, which up until this week's news, was not included in Volkswagen's massive diesel scandal. No recall is currently planned, according to Automotive News. Additionally, Volkswagen has yet to issue a stop-sale on its Touareg TDI, which also uses the 3.0-liter V6. The Touareg TDI can still be found on Volkswagen's consumer site, as of this writing.

Audi kills off its 420-hp four-cylinder engine project

Audi's supercar-slapping, fire-breathing four-cylinder concept engine will remain just that, with Autoblog confirming that it has been internally killed off. Speaking at the launch of the TT RS, the engineering boss of Audi's Quattro GmbH division, Stephan Reil, said the Volkswagen Group had stopped all development of the 420-horsepower, 2.0-liter four it showed in the 2014 TT Quattro Sport Concept car (above). Despite previous assurances that Quattro had roles for both the EA888-based engine and Audi's wildly charismatic 2.5-liter, five-cylinder motor, post-Dieselgate reality has killed the smaller engine. "The 400-horsepower EA888 engine is dead," Reil said. The EA888 engine was conceived and developed by the same man behind AMG's powerhouse 2.0-liter four. Friedrich Eichler left AMG to become the Volkswagen Group's gasoline engine development go-to guy, and he was confident the 420-hp engine could be turned into a production car quickly, as was then-Audi development boss, Ulrich Hackenberg. It was even suggested that because the EA888 engine family bolted straight into the Volkswagen Group's ubiquitous MQB small-car architecture, the little powerhouse could be cheaply and quickly dropped into any of the company's cars that needed an image boost. Since then, Quattro has elevated the five-cylinder motor, switching it to an all-alloy block with a magnesium oil pan to cut down its weight while boosting its power and torque levels. Where the four-cylinder engine was shown with 420 hp and 332 lb-ft of torque, the production version of the TT RS's new five-cylinder engine totes 400 hp and 354 pound-feet of torque. The smaller engine's proponents claimed a 0-62 mph acceleration figure of just 3.7 seconds for the concept TT that carried it, and it might not be a coincidence that the all-new TT RS claims exactly the same figure. The 2.0-liter motor had a torque peak that arrived at 2,400 rpm and began to taper off at 6,300 rpm, while its power apexed at 6,700 rpm, thanks in part to a turbocharger that could feed it up to 1.8 bar of air. Flip to the TT RS' data and you're looking at more torque at lower revs and a touch less power, but at higher revs. That's not a lot of wriggle room for the concept engine to operate, especially when the perceived value of the five-cylinder engine is higher than the four, and the four's development and production costs would be higher than the five's.

Bosch fuel pumps spark recall of 2015 Golf, GTI and Audi A3

A few weeks ago, BMW and Nissan both issued recalls for some of their vehicles to replace Bosch-supplied fuel pumps. The pumps had nickel plating that could flake off and cause a failure. Volkswagen Group is the latest automaker to be affected by the problem and has a campaign for the 2015 Audi A3, VW Golf and GTI. In total, 6,204 units of these models are in need of repair. The problem with the VW Group vehicles is identical to the previous recalls. It's possible for the pump's nickel plating to come off and cause increased friction. Eventually, this can result in the component's failure. According to documents from the National Highway Traffic Safety Administration (as a PDF, here), there are no reports of accidents or injuries from this issue in the VW Group models. Bosch spokesperson Linda Beckmeyer tells Autoblog that these vehicles don't all necessary share an identical fuel pump, but the parts all use the same plating process. The problem also prompted repairs of the 2014 Ford Escape several months ago, she indicated. When asked if the issue could prompt more campaigns, Beckmeyer said that she "can't speak to that" because automakers decide on the recalls. Owners should receive notice of the problem soon, but according to the NHTSA documentation, there currently aren't enough pumps to fix all of these vehicles. "Bosch is working closely with automakers regarding replacement parts," Beckmeyer said. When available, dealers will replace the components free of charge for affected customers.

SUMMARY: Volkswagen Group of America, Inc. (Volkswagen) is recalling certain model year 2015 Volkswagen Golf, GTI, and Audi A3 vehicles. Improper nickel plating of components within the fuel pump may result in the fuel pump failing. CONSEQUENCE: If the fuel pump fails, the vehicle will not start, or if the engine is running, it will stop and the vehicle will stall, increasing the risk of a crash. REMEDY: Volkswagen will notify owners, and dealers will inspect the vehicles and replace any affected fuel pumps, free of charge.
