VW fix would have cost $335 per vehicle

Since the Volkswagen diesel kerfuffle began, Bosch, the world's largest auto supplier, has been hooked up to a bullhorn trying to make sure everyone knows its side of the story. Bosch supplied VW with the engine management testing software, including delivery and metering modules, that VW then used to skirt emissions laws in the US. Bosch told VW in 2007 that it was illegal to use the software in cars it planned to sell yet VW did it anyway, according to reports coming out in German newspapers Bild am Sonntag and Frankfurter Allgemeine Zeitung. That first warning came two years after VW started developing the small-displacement diesel, around the time that the two men pushing its development, then-brand chief Wolfgang Bernhard and engineer Rudolf Krebs, were telling their superiors that the engine needed AdBlue urea injection to pass US emissions. VW cost controllers wouldn't approve the AdBlue solution because it would add 300 euros ($335 US) to the cost of the vehicle. Bernhard and Krebs left the same year that Bosch advised VW about the software, two years before the engine went into production. That's when things get cloudy. A report in Automotive News says that when Martin Winterkorn took over in 2007 as head of the VW Group and brand, he asked Ulrich Hackenberg and Wolfgang Hatz to keep working on the engine, and "[the] engine then ended up in VW Group diesels" with that problematic software still intact. No one has yet pointed any fingers at this latter chain of command, but like a game of Clue, right now they're the professors in the library holding the candlesticks. Warnings didn't only come from the supplier: Frankfurter says VW's initial investigation has found that an engineer issued the same caution to the company in 2011. Neither Bosch nor VW would comment on the reports.

VW diesel scandal: South Korea could be next

To no one's surprise, there are constant new developments in the VW diesel scandal. We hit the main points in a number of posts recently, but there were other, smaller developments that we didn't put into their own post. Instead, we've collected them here. For our complete coverage of this issue, click here. There's a lot to digest, so here goes. To try and keep dealers happy, VW announced that it guarantee bonus payments to its US dealers this month worth $300 for every new car sold ($600 for each Passat). The automaker is also going to guarantee payments from the company's customer experience bonus program. A memo from VW's US chief Michael Horn said, "We understand the pressure these recent events have put your business under and we are committed to providing you support," according to Automotive News. You can see Horn speaking at an event Monday night above. There will be at least one more official investigation into just how widespread this issue. South Korea has now said it will look into the emissions numbers for around 4,000-5,000 cars there. The affected TDI engines can be found in two VW and one Audi models (Jetta, Golf and A3) in South Korea. In the US, there could be another investigation as well, since Senator John Thune, (R-SD), the chairman of the Commerce, Science and Transportation Committee, has asked the Federal Trade Commission to take a closer look. A scandal this big is not only going to affect VW. To get ahead of any possible criticism, Bosch has issued a statement saying that yes, it does make parts for the 2-liter, 4-cylinder TDI engine that is at the heart of the problem. But, in a statement emailed to Reuters, said, "We produce the components after specification of Volkswagen. The responsibility for application and integration of the components lies with Volkswagen." Looking ahead, VW said in a new statement (available below) that its new EU 6 diesel engines do, " comply with legal requirements and environmental standards." That means that, supposedly, there's no "defeat device" needed to make these engines clean enough to pass strict environmental regulations. That'll be important if VW wants to keep marketing diesel as a clean fuel. For now, the tide seems to be turning against the automaker. Volkswagen AG has issued the following information: Volkswagen is working at full speed to clarify irregularities concerning a particular software used in diesel engines.

VW recalls 1.1M Jetta, Beetle models in US, China over suspension fears

Volkswagen is recalling about 1.1 million vehicles in China and North America in a newly announced campaign affecting the rear suspensions on some models. For the US, the action covers about 442,265 vehicles, including 400,602 examples of its 2011-2013 Jetta and 41,663 units of the 2012-2013 Beetle and Beetle Convertible. According to Reuters, the recall affects a further 126,000 vehicles in Canada and about 581,090 in China, including related market-specific models like the Sagitar.
The problem can occur if the affected models have a collision to the rear or the side-rear of the vehicle. It's then possible for the trailing arms on the torsion-beam rear suspension to be damaged. If the harm isn't noticed, then the part could fracture while driving. Obviously, a broken rear suspension is going to have an adverse effect on handling.
To fix things, VW dealers will inspect the trailing arms on the models, and they will all receive a sheetmetal part that will make a distinctive sound if broken in the future. If already damaged, the entire torsion beam will be replaced. Obviously, this work will be done at no charge to owners.
