BRUSSELS/BERLIN Dec 14 Audi's top-selling model
released excessive toxic diesel emissions in results from lab
tests run by the European Commission and seen by Reuters,
raising suspicions of wrongdoing at Volkswagen's
The results threaten to embroil Audi, the main contributor
to VW group profit, in the scandal that has engulfed the company
since it admitted cheating U.S. emissions tests with software to
mask nitrogen oxides (NOx).
The lab tests run by the European Commission's Joint
Research Centre (JRC) in August showed the latest Euro 6 diesel
generation A3 emitted 163 milligrammes (mg) of nitrogen oxides
(NOx) per kilometre, double the statutory 80mg cap.
A separate lab-based test showed the A3 emitting 140mg of
NOx at an engine temperature of 10 degrees Celsius, but
emissions were below 80mg when the car was run with a cold
"The differences between cold start and hot start are hard
to explain," said Bas Eikhout, a lawmaker on the European
Parliament's inquriy committee into the VW scandal.
Audi said that emissions of the A3 compact, which has topped
the brand's global sales rankings this year ahead of the A4 and
A6 models, comply with legal limits, citing "independent
measurements" of a 2-litre TDI EU6 model.
The Ingolstadt-based carmaker said it has no information
about the JRC tests, including the engine type examined by the
EU Commission's experts, and declined further comment.
EU regulators depend on the JRC's work to help to shape
policy, but member states are responsible for policing their car
A Commission spokeswoman said that the JRC's results were
"If the test results raise some suspicion of wrongdoing,
such as the installation of prohibited defeat devices, they will
be shared with all relevant approval authorities," she said.
Germany's KBA motor vehicle authority declined to comment.
Amid frustration in Brussel over inaction by governments
over the dieselgate scandal, the EU began legal action this
month against seven countries, including Germany, for not fining
VW over its use of illegal software.
VW has set aside 18.2 billion euros ($19.4 billion) to cover
the costs of the biggest corporate scandal in its history.
In Europe, however, VW has not admitted to using illegal
software. Carmarkers in the bloc say that an exemption in EU law
allows them to turn off emissions-control systems if that is
needed to protect engines.
Signs of further emissions irregularities come at a bad time
for VW as it tries to negotiate a deal with U.S. authorities on
possible buybacks and fixes for about 80,000 polluting Audi,
Porsche and VW 3-litre vehicles.
Audi also came under scrutiny last month over whether some
gasoline vehicles have separate software that lowered carbon
