| 18 | On 27 December 2017, GSMB Invest brought an action before the Landesgericht Klagenfurt (Regional Court, Klagenfurt, Austria), the referring court, seeking the annulment of that sales contract, on the basis of Paragraph 879(1) and Paragraph 932(4) of the ABGB, in return for payment of a fee for use. |

On 27 December 2017, GSMB Invest brought an action before the Landesgericht Klagenfurt (Regional Court, Klagenfurt, Austria), the referring court, seeking the annulment of that sales contract, on the basis of Paragraph 879(1) and Paragraph 932(4) of the ABGB, in return for payment of a fee for use.

| 19 | In support of its action, GSMB Invest submits that, in purchasing the vehicle in question, it had believed that it was acquiring a new environmentally friendly vehicle, the exhaust gas of which, in particular, complied with the legal standards in force. Following an update of the software installed in the electronic engine controller fitted in that vehicle, carried out by Volkswagen on 9 May 2017, the purification of exhaust gas was operational only at an outside temperature of between 15 and 33 °C and at a driving altitude of less than 1000 metres (‘the temperature window’). That temperature window constitutes a prohibited defeat device since it cannot be justified by any of the derogations provided for in Article 5(2) of Regulation No 715/2007. In particular, the reduction in the purification of exhaust gas that results from the temperature window does not protect the engine of the vehicle in question from direct damage. |

| 20 | Auto Krainer submits that such a temperature window is used by all manufacturers of diesel vehicles in the Euro 5 category and that the Kraftfahrt-Bundesamt (Federal Office for Motor Vehicles, Germany), the competent authority responsible for type-approval in Germany, has held that temperature window to be a permissible measure under Regulation No 715/2007. In addition, when reviewing the software update at issue, that authority found that it had no negative impact on the durability of the pollution control devices. |

In addition, when reviewing the software update at issue, that authority found that it had no negative impact on the durability of the pollution control devices.

| 21 | The referring court considers that it follows from Article 3(10) and Article 5(2) of Regulation No 715/2007 that the temperature window is a prohibited defeat device. In most countries of the Europe Union, in particular in Germany and Austria, the ambient temperature is more often than not below 15 °C throughout the year and, given the topography of those countries, vehicles are very often driven above an altitude of 1000 metres, so that such driving conditions may reasonably be expected to be encountered in normal vehicle operation and use, within the meaning of Article 3(10) of that regulation. |

According to that court, the derogation provided for in Article 5(2)(a) of Regulation No 715/2007 cannot provide a legal basis for defeat devices that are activated under ‘normal’ conditions of vehicle use.

| 23 | That court adds that Article 3(9) of Regulation No 692/2008 determines the period of time in which efficient operation of the engine must be achieved after a cold start. Under that provision, the NOx aftertreatment device must reach a sufficiently high temperature for efficient operation within 400 seconds after a cold start at ‐7 °C. The approval authorities may not grant EC type-approval where satisfaction of the conditions laid down in that provision are not sufficiently established. It follows from that burden of proof that the EU legislature has clearly established that a temperature window may not be justified if it does not meet those conditions. |

| (3) | Is Article 5(1) of [Regulation No 715/2007] to be interpreted as meaning that an exhaust gas strategy, which ensures pollution control devices operate efficiently only [in the temperature window] and therefore do not generally operate fully functionally during the year in Europe, in particular in Austria, does not fulfil the requirement of Article 5(1) [of that regulation] – operation of the vehicle under normal conditions of use – and constitutes a prohibited “defeat device”?’ |

| 26 | As a preliminary point, it should be borne in mind that, according to settled case-law, in the procedure laid down by Article 267 TFEU providing for cooperation between national courts and the Court, it is for the latter to provide the national court with an answer which will be of use to it and will enable the national court to determine the case before it. Consequently, even if, formally, the referring court has limited its question to the interpretation of a particular provision of EU law, that does not prevent the Court from providing the referring court with all the elements of interpretation of EU law which may be of assistance in adjudicating in the case pending before it, whether or not the referring court has referred to them in the wording of its questions. It is, in this regard, for the Court to extract from all the information provided by the national court, in particular from the grounds of the decision to make the reference, the points of EU law which require interpretation in view of the subject matter of the dispute in the main proceedings (judgment of 15 July 2021, DocMorris, C‐190/20, EU:C:2021:609, paragraph 23 and the case-law cited). |

| 28 | It should be noted that, in its written observations, Auto Krainer submits that the referring court erroneously describes the operation of the software at issue. It maintains that that software leads to a reduction in the exhaust gas recirculation rate when the temperature of the engine intake air, and not the ambient temperature, is below 15 °C. It is common ground, from a technical point of view, that the temperature of the engine intake air is, on average, 5 °C higher than the ambient temperature. The exhaust gas is therefore recycled fully so long as the ambient temperature is greater or equal to, not 15 °C, but 10 °C, that is to say, within the average annual ambient temperature range in Germany, which is 10.4 °C. In addition, Auto Krainer submits that that court fails to note that, when the ambient temperature is below 10 °C, the exhaust gas recirculation rate is only gradually decreased, in a linear way, to zero, until an ambient temperature of ‐5 °C. |

| 32 | The Court has held that that definition of a defeat device confers a broad scope on the concept of ‘element of design’, which covers both mechanical parts and the electronic components which control the activation of those parts, where they act on the operation of the emission control system and reduce its effectiveness (judgment of 17 December 2020, CLCV and Others (Defeat device on diesel engines), C‐693/18, EU:C:2020:1040, paragraph 64). |

| 34 | In the present case, it is apparent from the order for reference that the vehicle at issue is equipped with an EGR valve and software installed in the electronic engine controller. That valve is one of the technologies used by vehicle manufacturers to manage and reduce emissions of NOx generated by the incomplete combustion of fuel. The effectiveness of the pollution reduction system is linked to the opening of the EGR valve, which is controlled by the abovementioned software. Outside of the temperature window established by the software update and referred to in paragraph 19 above, the exhaust gas recirculation rate decreases in a linear way down to zero, which leads to the emission limits for NOx laid down in Regulation No 715/2007 being exceeded. |

| 40 | As is apparent from the very wording of Article 3(10) of Regulation No 715/2007, the concept of ‘normal ... operation and use’ of a vehicle refers to the use of the vehicle under normal driving conditions, that is to say, not only, as argued, in essence, by Auto Krainer in its written observations, to its use under the conditions laid down for the approval test, applicable at the material time of the case in the main proceedings, known as the ‘New European Driving Cycle’ (NEDC), which is carried out in a laboratory and involves the repetition of four urban cycles followed by one extra-urban cycle. That concept thus refers to the use of that vehicle under real driving conditions, such as are usually present in the territory of the European Union (see, to that effect, judgment of 17 December 2020, CLCV and Others(Defeat device on diesel engines), C‐693/18, EU:C:2020:1040, paragraphs 96 and 101).

| 41 | That interpretation is borne out by the context of Article 3(10) of Regulation No 715/2007.

| 52 | Consequently, the EGR valve, the EGR cooler and the diesel particulate filter constitute components that are distinct from the engine. The EGR valve is situated at the engine outlet, after the exhaust manifold. When opened, the EGR valve allows the exhaust gas to be passed through the gas inlet manifold in order to burn it a second time, with a heat exchanger, the EGR cooler, and to cool the burnt gas. The particulate filter, which is situated before the tailpipe, makes it possible to filter the air in order to retain the fine polluting particles. |

| 53 | As regards, next, the concepts of ‘accident’ and ‘damage’ referred to in Article 5(2)(a) of Regulation No 715/2007, the Court has previously held that, in order to be justified under that provision, a defeat device that reduces the effectiveness of the emission control system must allow the engine to be protected against sudden and exceptional damage (see, to that effect, judgment of 17 December 2020, CLCV and Others(Defeat device on diesel engines), C‐693/18, EU:C:2020:1040, paragraph 109). |

| 54 | The clogging up or the ageing of the engine cannot, in any event, be regarded as an ‘accident’ or ‘damage’, within the meaning of that provision, since such occurrences are, in principle, foreseeable and inherent in the normal operation of the vehicle (see, to that effect, judgment of 17 December 2020, CLCV and Others(Defeat device on diesel engines), C‐693/18, EU:C:2020:1040, paragraph 110). |

The interpretation of the word ‘damage’ given by the Court in the judgment of 17 December 2020, CLCV and Others(Defeat device on diesel engines) (C‐693/18, EU:C:2020:1040), is not called into question by the argument of the German Government and Auto Krainer that it follows from that word in the English version (‘damage’) and the German version (‘Beschädigung’) that that word does not cover only sudden and unforeseeable events.

| 58 | First, as the Advocate General observed, in essence, in point 115 of his Opinion, although, unlike the French definition, the definitions of that word in English and German do not necessarily imply that a removal is due to a ‘sudden’ event, they do not invalidate the Court’s interpretation of the word ‘damage’. Secondly, it should be recalled that the strict interpretation adopted by the Court is based on the grounds set out in paragraphs 50 and 55 above. |

Secondly, it should be recalled that the strict interpretation adopted by the Court is based on the grounds set out in paragraphs 50 and 55 above.

| 59 | However, the German Government and Auto Krainer submit that the defeat device at issue is justified because, in the event of temperatures that are too low or too high, deposits may be formed, during the exhaust gas recirculation, and thus lead to poor positioning of the EGR valve, namely, for example, it may no longer open or may no longer close correctly, or the valve may become completely blocked. A damaged or poorly positioned valve could cause damage to the engine itself and lead, inter alia, to loss of vehicle power. Furthermore, it is impossible to predict and calculate a threshold for when the EGR valve fault could arise, since it could take place suddenly and unpredictably, even if that valve has been maintained regularly. Sudden and unforeseeable losses of vehicle power would affect the safe operation of the vehicle, for example by considerably increasing the risk of a serious traffic accident when overtaking. |

| 60 | Furthermore, Auto Krainer submits that the clogging of components of the exhaust gas recirculation system, by causing the malfunctioning or even the blocking of the EGR valve, is liable to lead to the combustion of the particulate filter and to the engine catching fire, or even, as a result, to the entire vehicle catching fire, which would jeopardise the safe operation of the vehicle. |

| 61 | In that regard, it should be noted that it is apparent from the very wording of Article 5(2)(a) of Regulation No 715/2007 that, in order to fall within the exception provided for in that provision, the need for a defeat device must be justified not only in terms of protecting the engine against damage or accident, but also in terms of the safe operation of the vehicle. As the Advocate General pointed out in point 106 of his Opinion, in view of the use of the conjunction ‘and’ in that provision, it must be interpreted as meaning that the conditions laid down therein are cumulative. |

As the Advocate General pointed out in point 126 of his Opinion, however, such a determination is, in the main proceedings, part of the assessment of the facts which falls to the referring court alone. |

| 63 | Furthermore, while it is true that Article 5(2)(a) of Regulation No 715/2007 does not formally impose any further conditions for the application of the exception laid down in that provision, the fact remains that a defeat device which, under normal driving conditions, operated during most of the year in order to protect the engine from damage or accident and ensure the safe operation of the vehicle, would clearly run counter to the objective pursued by that regulation, from which that provision allows derogation only in very specific circumstances, and would result in a disproportionate infringement of the principle of limiting NOx emissions from vehicles. |

| 66 | In addition, Auto Krainer and the German Government submit that the concept of ‘need’ for a defeat device does not require the best available technology and that account must be taken of the state-of-the-art technology at the time of EC type-approval in order to assess whether that need is justified in terms of protecting the engine and for safe operation of the vehicle, within the meaning of Article 5(2)(a) of Regulation No 715/2007. It is not contested that the use of an EGR system which operates in line with a temperature window represents, to a different extent depending on the date of approval, state-of-the-art technology. Furthermore, Auto Krainer and the German Government submit that the interpretation of the word ‘need’ in that provision should take account of the need to balance environmental interests with the economic interests of manufacturers. |

| 67 | In that regard, it must be pointed out, as the Advocate General observed in point 129 of his Opinion, first, that it is apparent from recital 7 of Regulation No 715/2007 that, when the EU legislature determined the emission limits for pollutants, it took into account the economic interests of manufacturers and, in particular, the costs imposed on undertakings by the need to comply with those limits. It is thus for manufacturers to adapt and apply technical devices capable of complying with those limits as that regulation does not require the use of any particular technology. |

| 68 | Secondly, as stated in paragraph 55 above, the objective pursued by Regulation No 715/2007, which consists in guaranteeing a high level of protection of the environment and improving air quality within the European Union, means NOx emissions being effectively limited throughout the normal life of vehicles (judgment of 17 December 2020, CLCV and Others(Defeat device on diesel engines), C‐693/18, EU:C:2020:1040, paragraph 113). Permitting a defeat device under Article 5(2)(a) of that regulation solely because, for example, research costs are high, the technical device is expensive or vehicle maintenance is more frequent or more costly for the user would jeopardise that aim. |
