In the course of a general inspection, vehicles can enter a certain Defect category get ranked. If your vehicle has been classified in a corresponding defect category and the defect has not yet been remedied, violates the continued use of the vehicle against §§ 23 StVO and 31 StVZO.

The following classifications are possible:

  • HW (Notes): This shows no defects, but only shows defects that may arise in the future, such as wear or corrosion on. In any case, the inspection sticker AUSGESTELLT.
  • GM (Minor defects): Due to the minor defects none There is a special traffic hazard or environmental pollution, so the inspection sticker AUSGESTELLT if the defect complained about can be expected to be repaired immediately.
  • EM (Significant defects): A vehicle with this classification has either a Danger for traffic or one burden for the environment. A test sticker is therefore not assigned, for that one will Review necessary.
  • VM (Dangerous Defects): These vehicles represent an immediate Danger for traffic or one burden for the environment. It will, however no operating ban displayed. All defects are to be corrected immediately and one Review is required. The inspection sticker will be issued in the course of the HU can not be displayed. The licensing authority will, however can not be informed.

The emissions test (AU) is part of the general inspection, but what exactly is checked during this?

Until the end of 2009 the AU was a separate investigation. A passed AU was indicated by means of a hexagonal test sticker on the front license plate proven. The AU has been part of the HU since 2010 and the general "TÜV" badge is proof of a passed AU and HU. The specially issued badge is no longer applicable, but one must Extra confirmation of the passed AU always be carried. In principle, the AU may up to a maximum of two months and before the main inspection date in approved workshops be performed. In order to be recognized, the date of the AU must be true to the month (a maximum of 2 months in advance) to match.

With 1. January 2018 was also the mandatory to carry out a Tailpipe measurement introduced in the wake of the AU to the results more realistic and error-free close. Whether this improves the air quality or whether it is an additional one burden For every vehicle owner, everyone can decide for themselves.

Already for the 1. January 2021 the next innovation was planned, one for vehicles with diesel engines Particle count measurement should go through. However, since the necessary device specifications and device approvals had not yet been completed, the start date of the review has been indefinitely postponed. "back

Innovations at AU:

For motor vehicles with On-board diagnostic system (OBD system) has been omitted since January 1, 2018 two-step process, whereby no measurement more is required on the exhaust if the OBD system passes the test. This rule applies to all after January 1, 2006 registered motor vehicles, with Exception of motorcycles and motor vehicles of the Emission classes 6 / VI and above. In the case of the vehicles affected by this regulation, the OBD system check is now a mandatory exhaust gas measurement at the exhaust extendedwhich checks whether all limit values ​​are observed. There are from the manufacturer of the vehicle prescribed limit values for the carbon monoxide content (CO), the fuel-air mixture (lambda) in Otto engines and the so-called Smoke opacity (Absorption coefficient) for diesel engines.

These are the manufacturer's specifications:

  • CO content <= 0,2% vol
  • Lambda from 0,97 to 1,03
  • Absorption coefficient <= 1,5 m-1
    (also known as the badge value)

Zum 1. January 2019 However, the limit values ​​for vehicles of the Euro 6 / VI class and higher were set to the following values lowered:

  • CO content <= 0,1% vol
  • Absorption coefficient <= 0,25 m-1 "back

For which vehicles does an AU have to be carried out and which not?

Basically must all vehicles that require registration with a Otto or diesel engine also to the AU. This includes cars and trucks, as well as motorcycles and light motorcycles, trikes, quads and many other motor vehicles.

But there are also some exceptions:

  • Motor vehicles with Otto engine which have the maximum speed of Do not exceed 50 km / hOr before July 1, 1969 were admitted, or over three wheels or have a total weight of below 400 kg.
  • Motor vehicles with Diesel drive, Which have fewer than four wheels, or a top speed of 25 km / h can not be exceed or and before on January 1, 1977.
