    As the Diesel Emits: Audi Admits There Is Defeat Device In 3.0L TDI V6, Announces Fix

      Audi Reveals the Defeat Device in Question on the 3.0L TDI V6, Along With Announcing A Fix


    Audi announced this afternoon that the 3.0L TDI V6 did have a defeat device that allowed the engine to circumvent U.S. clean air laws.

     

    In a statement, the German automaker said that it failed to disclose three emission control software functions, also known as auxiliary emissions control devices (AECD) to the various agencies as required by law. One of devices, a 'temperature conditioning of the exhaust‑gas cleaning system' was deemed to be illegal by the EPA as it could detect when it was being tested for emissions and turn on the pollution-control equipment to cut emission levels down.

     

    Audi also announced the plan to fix the vehicles that will involve a software update to 85,000+ vehicles with the V6 diesel. The company will submit new U.S. government emission certification paperwork for the software. If approved by the EPA and California Air Resources Board, Audi will release software to dealers to perform the fix,

    Statement on Audi’s discussions with the US environmental authorities EPA and CARB

    • Auxiliary emission control devices (AECD) for US version of V6 TDI 3 liter engine to be revised, documented and submitted for approval
    • Technical solution for North America versions from 2009 model year onwards to be worked out in conjunction with the authorities


    Audi will revise, document in detail, and resubmit for US approval certain parameters of the engine-management software used in the V6 TDI 3 liter diesel engine. That is the result of the discussions held between a delegation from AUDI AG and the US Environmental Protection Agency (EPA) and the California Air Resources Board (CARB). The updated software will be installed as soon as it is approved by the authorities. The three brands Audi, Porsche and Volkswagen are affected. Audi estimates that the related expense will be in the mid-double-digit millions of euros.

     

    The latest discussions focused on a notice of violation of November 2, in which Audi was informed that AECDs (Auxiliary Emission Control Devices) were not sufficiently described and declared in the application for US type approval. That will now be done with the updated software and the documentation.

     

    Audi has confirmed that three AECDs were not declared in the context of the US approval documentation. One of the AECDs relates to the temperature conditioning of the exhaust‑gas cleaning system. The other two AECDs are for the avoidance of deposits on the Ad-Blue metering valve and of HC poisoning of the SCR catalyst with unburnt hydrocarbons. One of them 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 has agreed with the environmental authorities on further steps of cooperation in which the concrete measures to be taken will be specified. The company has committed to continue cooperating transparently and fully. The focus will be on finding quick, uncomplicated and customer-friendly solutions. The voluntary sales stop for models with the V6 TDI diesel engine, which the three affected Group brands had provisionally decided upon, has been extended until further notice.

     

    This engine was developed by Audi and is used in the Audi US models A6, A7, A8, Q5 and Q7 from model year 2009 onwards. Volkswagen uses the engine in the Touareg and Porsche has used it in the Cayenne since model year 2013. All affected models continue to be safe and roadworthy.

    Weird, as I thought myself and a few others had already commented on this thread.

     

    I think VW is going to have to double the money they have put aside for this whole mess, I expect a few more diesel models to still come up as having the defeat modules.

      Germany. Known for impeccable engineering, German vehicles usually have cutting-edge technology and are status symbols. Sweden. The Swedish are known for safety, and even though the only brand from Sweden is Volvo, they want to have a sleek design while making vehicles easy to drive. South Korea. In my opinion, South Korea is doing a great job with their vehicles. Creating Genesis as a stand-alone brand was genius because they can have vehicles close to or competing with the Germans while costing thousands of dollars less.
      What vehicles did I choose from these three countries? First, we have the Genesis G70. The particular G70 I am talking about is the G70 3.3T. It can compete directly with the Germans in terms of performance and safety features. Next, we have the Volvo S60 T6. It ties the Audi S5 Sportback in terms of exterior and interior looks and follows the tradition of being a Swedish car that focuses on safety which a hint of performance. The powertrain may be a little odd, but I’ll discuss engines and performance later. The black sheep here is a used Audi S5 Sportback? Why this car and not an S4? Simple, the S4 is too plain. The S5 Sportback is a good-looking car with performance similar to the Genesis, but a new one’s cost puts it in a different bracket.
      There is a reason why I’m using these vehicles. Price and performance. First, price. Options I look for such as blind-spot monitoring, adaptive cruise control, digital displays, all-wheel-drive, and heated/ventilated seats push up the prices for these three from $50,000-$53,000. Although the G70 and Volvo can be bought for around $40,000, a few options bump their prices up. Let’s dive into what I recommend for each car.
      Not a surprise, the Genesis G70 comes in at $50,000. You can get a Sport Package, but I would go with the Prestige Package because it has a heads-up display, surround-view monitoring that makes parking easy, and advanced safety features with a feature to not his pedestrians. That last feature is very helpful in a city like Chicago with Chicagoans crossing the street anywhere. 
      Volvo’s S60 T6 has three trim levels, and I would go with the Inscription. You can pick an interior that isn’t just black as well as a Harman Kardon sound system. Two packages I recommend are the Luxury Package which gives you massaging seats, ventilated seats, and upgraded Nappa leather. The Advanced Package grants you the ability to use Pilot Assist, an almost semi-autonomous system which houses every safety system a car can have. 
      A brand spanking new Audi S5 Sportback starts at $52,000 and it being German, the options are expensive and expansive. Although I would recommend the Premium Plus, if you want a head-up display, adaptive cruise control, and parking assist, you must go for the $59,000 Prestige. You can get a Black optic package that changes some of the exterior trim to black, hence the name. Ventilated seats cost $550 with the Warm weather package and a heated steering wheel is $750 in the Cold weather package. Final cost: $63,000, over $10,000 more than the Genesis and Volvo. 
      Now for the nerd talk of performance and driving dynamics so if you really don’t care, just go to the last sentence in this paragraph. We have the most powerful car, the Genesis G70, with a turbocharged 3.3-liter V6. Stats: 365 HP and 376-pound feet of torque. 0-60: 4.5 seconds. Next, the Volvo T6. The T6 uses a turbocharged and supercharged 2.0-liter inline 4. Stats: 316 HP and 295-pound feet of torque. 0-60: 5.9 seconds. Finally, the Audi S5 Sportback. Under the hood is a turbocharged 3.0-liter V6.  349 HP and 369-pound feet of torque. 0-60: 4.5 seconds. What does this mean? Two cars are fast, and one car isn’t. There we go.
      All vehicles have a sports feature that can change the noise of the engine inside, change how the steering feels, and how much more the engine will rev. If you’re into engine and exhaust noise, the Genesis is king. It is also the most powerful and feels the sportiest when going around a bend or going onto an on-ramp or wolfram. The Volvo has the worst sounding engine and there is a lot of lag because of the unusual engine. Volvo only uses 2.0-liter engines and it really hurts in terms of performance and it is more about cruising than going on twisty curves. Audi’s S5 Sportback is like the G70 in terms of engine noise and performance. Both are quick with V6 engines. In the Audi, the engine sounds good, but the steering feels disconnected. It handles alright but doesn’t feel special.

      Interior and infotainment systems are where the Genesis fall behind. The interior does feel luxurious, but the Volvo crushes it. A small infotainment system does it no justice. Volvo’s interior is gorgeous, but the infotainment system does something I hate: it controls almost everything. Why can’t there be regular controls for the climate control? Audi uses digital dials which are simply amazing and it has the best infotainment system. 
      Now we get to what the title implies: Who should get which car?
      Genesis G70 3.3T: This is the car you get if you are all about those stats and performance. The interior may be lacking a bit, but the standard features make up for that downfall. Its exterior styling is a bit bland so style gurus will want to look elsewhere. Otherwise, this is a wonderful job and I think Genesis should be proud. 8/10
      Volvo S60 T6: Simply put, this isn’t a sports sedan. Instead, it is a great long-distance cruiser with so many safety features it can almost drive itself. It has the best looking exterior and interior, but the infotainment system and droning engine let it down. Volvo is doing an amazing job creating beautiful looking vehicles, but I wish they didn’t only use 2.0-liter engines. 7/10
      Audi S5 Sportback: New, it’s the most expensive but as a used car, you can get one for a little over $50,000 with around 30,000 miles. Why get this? Because it’s all about that badge, baby! It does have a great interior and the best infotainment system. It ties the Volvo for a beautiful exterior as well. If you can find one as a certified pre-owned vehicle or CPO, you can save about $10,000. 8/10

      My personal favorite part: It’s performance facts time!
      Genesis G70 3.3T: Turbocharged 3.3-liter V6. Stats: 365 HP and 376-pound feet of torque. 0-60: 4.5 seconds.
      Volvo T6: Turbocharged and supercharged 2.0-liter incline 4. Stats: 316 HP and 295-pound feet of torque. 0-60: 5.9 seconds.
      Audi S5 Sportback: Turbocharged 3.0-liter V6.  349 HP and 369-pound feet of torque. 0-60: 4.5 seconds.
