Audi service tech joyrides customer car, allegedly takes drugs on the way [UPDATE]

UPDATE: We've received and added an official statement from Audi Palo Alto. Dealerships get a bad rap. Stories about sleazy salespeople and overpriced service procedures abound, even though the reality is that most dealers are run by and employ honest, fair folks. But just because the bulk of dealers and their employees are good people, it doesn't mean some bad eggs won't slip through the cracks. Audi Palo Alto, in the heart of Silicon Valley, is finding this out the hard way after dash cam video of a service tech abusing a customer's car started blowing up on YouTube. In the video, which you can watch above, the unnamed service tech took YouTube user Carrera Chris's Audi – it's not clear what model, but it sounds like one of the company's higher-performance 3.0-liter, supercharged V6 models – for a rather spirited test drive. There are plenty of wide-open-throttle runs mixed in with some speeding – the dash cam's lower display shows 90 miles per hour at one point on the freeway – and you can hear the driver laughing throughout. None of this is too remarkable on its own, and maybe not enough to get the tech fired. Until, that is, he pulls into a parking lot and begins snorting something. The dash cam doesn't show the technician, so it's impossible to determine what substance – if any – the driver is allegedly taking. It could be coke, could be crushed up pills, or, hey, it could be a prescription nasal spray (it is allergy season, even in perpetually lovely northern California). Carrera Chris does say he found white powder in the seams of the driver's seat, so take that for what it's worth. There are five videos that include 12 minutes of footage – the one up top is a summary, while the four below show the alleged drug use and some more mundane footage. We've reached out to Audi Palo Alto's general manager, Jason Mattia. He wouldn't answer our questions over the phone, but did forward an official statement from the dealer. An unfortunate incident was brought to our attention earlier this week. We immediately began our investigation and have already taken action. We are working with the customer involved and have thanked them for bringing this matter to our attention. At Audi Palo Alto, we are proud to be a part of the San Jose community. We value and respect our customers, and our team of 75 employees strives to deliver the highest level of customer service.

Volkswagen reportedly to name Matthias Muller CEO

Porsche chief executive officer Matthias Muller is expected to be named CEO of Volkswagen AG, the Wall Street Journal and other sources reported Thursday morning. Muller, 62, has led Porsche since Oct. 1, 2010, and jumpstarted the sports-car brand's expansion around the world. He replaces Martin Winkerkorn, who stepped down Wednesday amid the company's worsening diesel scandal. At least three more executives are also expected to be fired, including Volkswagen's US chief and the heads of Audi and Porsche research and development. Both brands are divisions of VW. A US spokesman wouldn't confirm the reports. An official announcement is expected at VW's board meeting on Friday. Muller's ascension caps a stunning week of turmoil for Volkswagen, which manipulated software to make its diesel-powered vehicles appear cleaner during testing that they are in real-world driving. The charges were revealed last week by the EPA, which cited the work of researchers at West Virginia University. About 482,000 vehicles are affected in the United States, which will be subject to recall, and VW estimates about 11 million of its vehicles around the world have the rigged software. The well-regarded Muller was viewed as a front-runner for the job even before Winterkorn stepped down. Before helming Porsche, he oversaw all vehicle projects globally for VW from 2007-2010. Previously, he was in charge of the Audi and Lamborghini product lines, and earlier in his career was responsible for the Audi A3 program in the 1990s. He joined Audi in 1977. He's trained as a toolmaker and studied information technology in Munich. His last name is sometimes spelled Mueller in English. Muller faces immediate challenges as he takes over VW's sprawling 78-year-old industrial empire, including recalls and regulatory actions around the world. In the US alone, the company faces a fine of up to $18 billion. VW, an industrial symbol of Germany, is also far larger than any unit Muller has run in his career. While Porsche sold 189,849 vehicles in 2014 globally, it's one of many VW brands. Collectively they sold 5.04 million vehicles through the first six months of this year, making Volkswagen the world's largest automaker. Related Video:
