US EPA accuses VW of cheating in oil burner tests

Hmmmmm

[fredgroves]

VW shares down 20% over this... the fine could be $18 billion!

What they did was to be able to spot the parameters of the EPA test and back off the output of the engine to reduce emissions...in software.

I wonder if the same software can detect the also very clearly defined Euro6 test.... I'm sure thats coming.

Accused and VW have admitted it...

As for the Euro testing for emissions... could be interesting... I had no doubt that the software can be written to recognise the conditions for the test... I wouldn't be surprised if it was similar here 

[fredgroves]

Well, they both use a prescribed test using a dynamometer

Here is the EPA's:

Here is the EU one:

What the VW software does it to spot this well defined EPA pattern, coupled with other clues like lack of steering input etc etc.

We already know that the Mk7 is able to detect steering inputs and use it to trigger things - eg the "are you awake" thing and also for the city/emergency braking response....

Down another 20% today, South Korea on it:

Doesn't affect UK engines just the e189 US diesel engine.

[fredgroves]

Well, yes, the EPA is a US regulator and they are only interested in products manufactured for the US market.... however this almost certainly will spill over into examination of cheating in other countries and by all vehicle manufacturers... and it already has as you can see above.

Doesn't affect UK engines just the e189 US diesel engine.

VWAG have announced this 'software' is in 11 million vehicles across the world not just US.

[mcmaddy]

The software might be but eu6 cars are apparently all legal.

Has VW stated this?
