Volkswagen will officially recall all of its illegally polluting diesel engines in Germany, German newspaper Die Welt reported Monday (via Reuters), the first step in a wave of recalls to fix 11 million cars worldwide.

Roughly 2.5 million cars in Germany will be recalled — 1.5 million Volkswagens, 500,000 Audi and 500,000 Skoda- and Seat-branded cars — with work beginning in January. Last week, the German transportation authority approved Volkswagen’s fix for 1.6-liter cars, which included an “air calming” pipe ahead of the intake’s air sensor. The company’s 1.2- and 2-liter cars may only need software fixes.

Officials from the U.S. Environmental Protection Agency and the California Air Resources Board will review Volkswagen’s proposal submitted earlier this month for fixing 482,000 cars in the U.S. It’s unclear what those fixes may be. During congressional testimony in October, Volkswagen of America chief Michael Horn said it would be a combination of hardware and software fixes.

Volkswagen Polo

German newspaper Bild Am Sonntag (via Reuters) reported Sunday that engineers within Volkswagen knew more than one year ago that its cars didn’t meet reported fuel consumption and even pulled a model from sale because of the deception.

Volkswagen admitted in October that 800,000 cars sold in Europe didn’t meet advertised fuel economy and that the company would pay more than $2.1 billion for the scandal.

According to Reuters, Volkswagen didn’t comment on the claim that executives knew about the cheating crisis before October, and said that the slow-selling Polo BlueMotion was pulled due to poor sales.

It’s hard not to look at the newly announced Volkswagen Beetle Dune and hear at the same time that Volkswagen will be saving $2 billion by cutting unnecessary trims and variants from their lineup.

I mean, it’s like they’re not even giving the little guy a chance.

Nonetheless, Bloomberg (via Automotive News) reported Friday that Volkswagen will axe trims and variants of its cars to reduce complexity and cost from its lineup to help pay for the company’s massive emissions scandal. Bernd Osterloh, Volkswagen’s labor chief, told journalists Friday that the company has needed to trim some of its fat for a while, apparently.

Audi has suspended two engineers for their involvement in helping Volkswagen’s larger 3-liter diesel engine pass emissions, according to Audi’s CEO. (Or you know, Volkswagen’s other, other emissions scandal.) The engine is used in the Porsche Cayenne and Audi’s range of sedans and crossovers.

Audi CEO Rupert Stadler told German newspaper Donaukurier that two engineers were suspended Wednesday and that the company was learning about its engines along with the rest of us.

2015 Volkswagen Jetta TDI (1 of 8)

Editor’s note: This article originally ran September 22, 2015. TTAC has yet to be proven or disproven on these numbers, but hopefully we will learn the truth soon.

In all reality, Volkswagen probably won’t pay $37,500 for each car that cheated its way through U.S. emissions standards, but the German automaker will probably pay thousands for each car to fit a device that would clean up their acts.

The presumed fix would come by retrofitting a Selective Catalytic Reduction (Adblue or urea) system although that wouldn’t be the only fix necessary. Researchers discovered that the Passat TDI that they tested, fitted with the SCR system, was 5 to 20 times over the NO limit — less than the 10 to 40 times by the lean NO filter cars, but still illegal.

The long list of items needed to fit models of the Volkswagen Golf, Jetta, Beetle and Audi A3 doesn’t include the engineering needed to retrofit the cars and the costs to crash test the models after the significant modifications. That’ll add hundreds of millions to the bottom line.

Volkswagen in Germany announced Wednesday its fix for millions of its 1.6- and 2-liter diesel engines in Europe that are illegally spewing nitrogen oxides and have cost the company billions in a massive worldwide scandal.

According to the automaker, a small “flow transformer” would be fitted in front of the air mass sensor in 1.6-liter, EA189 engines. The small transformer will calm air leaving the air filter before reaching the sensor. Volkswagen says the calmer air will allow the sensor to more accurately measure airflow for combustion. The fix would take less than an hour. For 2-liter engines, the proposed fix would be a software update and would take 30 minutes. Both plans have been approved by the German transportation authority.

Both fixes may be headed to cars in the U.S. However, the announced plan was in Germany for engines only on sale in most of Europe. Volkswagen submitted its U.S. plan last week to the Environmental Protection Agency and California Air Resources Board, but details of that plan haven’t been released.

Audi Goodwill

Audi announced last week that owners of its A3 TDI model would be offered the same goodwill program available to Volkswagen TDI owners.

The program, which started Nov. 20, offers owners the same $500 prepaid Visa card that can be used anywhere and a $500 dealership gift card that can be used at Audi dealerships. Three years of roadside assistance also will be included in the goodwill program.

According to Audi’s diesel information site, accepting the goodwill package doesn’t preclude owners from suing Audi in the future. Read More >

A German environmental group said Tuesday that its testing has revealed Renault’s Espace, when equipped with a 1.6-liter diesel engine, could emit up to 25 times the allowable limit of nitrogen oxides with a warm engine running on roads — or you know, the real world.

According to the New York Times, the Deutsche Umwelthilfe (DUH) didn’t directly accuse Renault of including cheating software in its cars — a la Volkswagen — but said the van polluted significantly less when the engine was cold. The results could show the schism between European testing standards — where tires can be over-inflated, doors taped up, batteries disconnected, seats removed — and real-world conditions.

Renault said in a statement Tuesday that its van complied with regulations and that tests done by researchers at the University of Bern “are not all compliant with European regulations.” Read More >

2014 audi a6 tdi side

Audi, a brand within Volkswagen Group that markets the majority of 3-liter diesel engines sold by the group in the United States, released a statement Monday detailing how it plans to fix vehicles that use a defeat device. The automaker also stated that three separate Auxiliary Emissions Control Devices — not just one — are used in 2009 and later 3-liter diesels used by Audi, Volkswagen (Touareg) and Porsche (Cayenne).

AECDs for those engines will “be revised, documented and submitted for approval,” Audi said in the statement.

Of the three AECDs, the EPA questioned the legality of a temperature conditioning procedure of the exhaust-gas cleaning system.

“One of (the AECDs) is regarded as a defeat device according to applicable US law. Specifically, this is the software for the temperature conditioning of the exhaust-gas cleaning system,” Audi said in a statement.

On Friday, Volkswagen of America detailed its plan to fix nearly 500,000 illegally polluting diesels in the United States to officials with the Environmental Protection Agency, the government body announced in a statement late Friday. The automaker was required to detail the fix no later than Friday.

The EPA, along with the California Air Resources Board, will review the proposal, said the statement. However, the EPA did not detail the proposal to the media or public and did not give a timeframe on when to expect the proposal to be detailed publicly.

The proposal only addresses issues detailed by the EPA in its September 18 Notice of Violation that applies to Volkswagen’s 2-liter diesel engines and not the 3-liter diesels which may also be cheating emissions tests.
