<em><strong>Rumors have been swirling for months that GM's arm in Europe, Opel, would be implicated in the dieselgate scandal-- just over the weekend serious allegations took flight that Opel does in fact use defeat devices in two diesel models. </strong></em>

Opel has been summoned to appear in front of a German Transport Ministry investigative committee this week to<a href="https://practicalmotoring.com.au/car-news/opel-and-fiat-summoned-to-answer-emissions-questions-in-germany/" target="_blank"> answer claims that its cars are capable of skirting emissions laws</a>.

<a href="http://www.spiegel.de/auto/aktuell/opel-experten-finden-weitere-abschalteinrichtungen-a-1091959.html" target="_blank"><em>Der Spiegel</em></a> reported last week the Opel Astra was found to contain software that will deactivate emissions control systems when the outside temperature is either below 20 degrees Celsius or above 30 degrees Celsius. Additionally it was discovered the emissions systems do not work when engine speeds exceed 2400 rpm; the car is moving faster than 145 km/h; or ambient air pressure is less than 915 millibar, indicating an elevation ofmore than 850 meters.

<em>Spiegel</em> claims the software was detected by investigating the specific motor controls, as well as observed discrepencies between the lab tests at TUV Nord in Essen and on road testing.

Opel is playing a game of semantics here; their official response being we do not use software*"which determines whether a car is subjected to an emissions test." However the effect is ultimately the same, exhaust treatment is only operational during testing.

Meanwhile in the Netherlands, RDW, Dutch authority which issued EU type approval for the Opel Zafira Diesel, <a href="http://www.tagesschau.de/wirtschaft/abgaswerte-opel-109.html" target="_blank">is considering a recall</a> and a possible, but unlikely, loss of approval.

Where the situation gets muddy is when you look at EU type approvals.

Yes, the <a href="http://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX:32007R0715" target="_blank">rules state</a>*“the use of defeat devices that reduce the effectiveness of emission control systems shall be prohibited,” but at the same time the rules also state the prohibition shall not apply "when the need for the device is justified in terms of protecting the engine against damage or accident and for safe operation of the vehicle.”

Effectively automakers can drive a bus through a loophole large as that, simply by stating an engine could be damaged while operating in certain ambient temperatures with the emissions controls operating. It's as simple as that.

Unfortunately until the the regulations are tightened up the manufacturers will continue to exploit loopholes.

Effectively the industry is operating under the old adage "if you ain't cheating, you ain't trying"-- if one automaker refuses, another won't, handing them a competitive advantage.

Call it the Lance Armstrong defense...

Lets hope they get this worked out before Chevy and the Cruze gets drug into the mess as well.

WHAT DIFFERENCE DOES IT MAKE??????????:confused:

Don't panic!

The high emissions issue is affecting all manufacturers in Europe - they all cheat, most of them more than VW, but their cheats don't technically break existing rules - different to VWs situation in the USA.

Opel are already making changes to their cars, some being made available for retro-fit on existing models, so they won't be unduly bothered, at least no more than any other manufacturer.

The 1.6 Whisper diesel is developed primarily by Opel (from it's Fiat origins) but I presume that Chevrolet would have done all the ECU programming to ensure it meets the US regulations - so if there is an issue it'll be down to Chevrolet, not Opel.

Operating only from 20-30 C is a farce in a climate with average temperatures of 10 or below!

Couple it with the "accidentally" higher fuel economy figures of the Lambda triplets and one must begin to ask these questions. http://www.gminsidenews.com/articles/gm-issues-stop-sale-on-2016-lambda-based-crossovers/

When VW did it, everyone was all for lynching, but now that its GM, our answers are sarcasm and so what?
I agree that the Opel diesel thing is an issue, I just think that the thread title "Is GM About to be Swallowed by the Dieselgate Maelstrom?" is a bit 'fantastical'.

Regarding the VW debacle, I'm not for lynching them. I think the whole thing is hilarious. The stuffed shirt Germans and the American 'save the planet' types have had the whole thing blow up in their face - awesome.

What bothers me is they violated the spirit of the law, though they complied to the letter of the law. The problem is that if the market leader, VW, was flat out cheating what option did any of the lesser brands have? Most of the other manufacturers must have known (I think a few articles were posted saying that GM did suspect), why didn't they turn in VW? To compete with VW's cheats there are really only two choices - make their own cheat or turn in VW. I would've ratted out VW in seconds.

I'm thinking a warning label, such as the gun free zone signs, should work.

CAUTION! USE THIS VEHICLE AT TEMPACHEERS BELOW 20C OR ABOVE 30C AT YOUR OWN RISK!

Next!

They programmed the emissions equipment to deactivate under pretty common conditions. I'd say they are in deep ****.

Last I checked Opel is the defacto European arm of General Motors, or did I miss a press release?

EDIT: In case you forgot, the new Cruze is getting the 1.6 diesel from Europe-- it was co-developed by Opel and GM http://www.roadandtrack.com/new-car...iesel-powered-cruze-using-fancy-german-words/
Opel sells a fraction of what VW sells, PERIOD, and the number of Cruze diesels on the road might require a second set of fingers and toes.

No big. All this says is that the gubment greenies are enough out of touch with reality for mass cheating to be seen as a viable course of action.
