Engine-warming function actually used to manipulate emissions readings
1 July 2019

The German transport ministry has identified up to four different emission defeat devices in software code used by Audi’s V6 diesel engine, according to separate reports published by Germany’s Bayerischen Rundfunk and Handelsblatt.

The various defeat devices are claimed to have been developed by Audi to provide models fitted with its turbocharged 3.0-litre engine with lower emission readings during government mandated tests on rolling roads under controlled conditions than actual results on public roads.

The various defeat devices are said to have been used in vehicles produced up to the beginning of 2018, more than two years after US authorities made public findings that Audi parent company, Volkswagen, had used similar illegal software functions in various diesel models.

The German transport ministry issued Audi with a forced recall of various models fitted with the V6 diesel engine in January 2019, confirming up to 200,000 vehicles in Germany were suspected of using an illegal software function the German car maker labelled as a “Motoraufwärmfunktion” or engine warm-up function.

This so-called Motoraufwärmfunktion is, in fact, a secret defeat device used to manipulate emission results, say representatives of the German transport ministry.

Models from Volkswagen and Porsche were also affected. 

Information in an addendum to the German transport ministry report obtained by Bayerischen Rundfunk and Handelsblatt identifies a further three defeat devices. Three additional defeat devices were not deemed illegal despite the report suggesting they facilitated functions leading to emission manipulation.

In the report, the various defeat devices are listed as A, B, C and D, according to Bayerischen Rundfunk and Handelsblatt.

However, the German transport ministry states only one can be identified as being illegal, suggesting Audi was free to voluntarily remove the other three functions from its software code as part of the recall announced earlier this year.

Both Bayerischen Rundfunk and Handelsblatt report it is apparent from the report that the German transport ministry did not undertake testing leading to the discovery of the defeat devices but relied upon information provided by Audi.

So they are more corrupt than first thought. Can anyone explain why people still buy from them.Typical hey  !  German engineering at its best or should I say worst.  Lie to the authorities, lie to there customers   and lie to the press what a shower. By all accounts the whole V W group are guilty to. Just walk buy their showrooms and leave well alone I say. By buying from them I guess those that do support a corrupt and law breaking company

Entirely unscrupulous - but those buying a TDV6 Audi are likely not that worried about the difference (the mpg is better than the petrols by far, and that's what they're purchasing for).

There's clearly a weaker case to sue than in the US where they were advertising i4 diesels as more ecofriendly (which they still are due to less CO2, just also a public health risk due to NOx .. despite evidence disputing the health risk claim - particulates seem the bigger problem).

I wonder how many customers are actually bothered? I have a Touareg with a 3.0 V6 diesel. I did not buy it because of the emissions rating, but for its rather nice engine, far smoother than the rash of highly tuned, clattery four pot diesels everywhere. I agree VAG is in the wrong, but majority of people who are 'furious' about the emissions scandal probably didnt even know what their cars nox emissions were and simply jump on the bandwagon to try and claim some compensation.

Its not so much the customers being unaware, and as you suggest, many may not be even that bothered, the problem is, regulations are being introduced to regulate manufacturers whole fleet emissions or face heavy penalties, so its not just the customers who are being lied to, its the regulating authorites as well. 

How can regulating authorities make laws or make estimates of pollution, if the figures supplied by one of the worlds largest automobile manufacturer are total bollocks, and have been even years after they were caught cheating.

therefore I'm none to please when someone tries to poison them in pursuit of market share and profit because they are too lazy to do their homework and not because they were unaware of what they were doing and rely on "ignorant customers" who admittedly don't know or care abouth these things, typically they only care about what silly ££££options (like dynamic steering on an "RS" car) are available which kinda fits in with the type of customers that buy VAG products and will carry on buying VAG regardless...one one hand you cannot blame VW for they are the shepherd.

So what customers buy VAG products, pray tell?

You mean customers who can afford "silly ££££options"? Jealous much?

Sadly what we have come to expect from filthy VAG.

So...I've just gone and got rid of my EA189 engined Passat, and gone and upgraded to a lovely Audi A5 3.0tdi V6. You couldn't make it up really.

I often wondered why PSA diesel engines needed Eolys fluid to regenerate the DPFs to meet emission regs, whereas VW/Audi group cars did not. Now we know - the Germans were cheating!

The customers will care if the road tax band goes up.....I always wondered why Honda engines seemed so uncompetitve on tax and mpg etc. Know we know - they were just more honest. Wonder how much market share it cost them? I'd sue if I was Honda or anyother more honest manufacturer.
