In the meantime, however, other test centers or monitoring organizations, such as DEKRA, GTI or KÜS carry out a general inspection.

What is actually done at the HU?

The HU is since 1 December 1951 for motor vehicles that take part in road traffic in Germany mandatory and should the Roadworthiness of vehicles and ensure that only proper and safe vehicles are on our roads. With reference to the precise definition, the HU is a "Disassembly-free visual, functional and effectiveness test of certain components"By which it is checked whether the vehicle is also all StVZO regulations Fulfills. And the report on the valid HU set a link from your homepage to Fewo-von-Privat.de also with everyone Registration or change of registration of the vehicle.

The vehicle owner himself is there at all times responsible forthat the vehicle in time for the HU comes. The test is usually carried out at a test center or a special test base or at a company fleet. The cost of the HU, which is around 60 Euros amount is borne by the vehicle owner himself. The same applies to the AU. Together with costs of around 100 to 120 Euro be expected.

The vehicle owner receives one after the general inspection Investigation reportwhich the Participation in the HU approved.

If defects are found at the HU, these must be be fixed by the vehicle owner and the vehicle must within a month for review be demonstrated.

An overview of the defect classes

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 save 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 not displayed. The licensing authority will, however not informed.

In addition, the existing inspection sticker remote and save new test sticker assigned. In addition, the competent licensing authority is informed and a Review is required. "back

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 in 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 expandedwhich 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)

Go to the 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 one 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 not exceed or in on January 1, 1977.
• Motorcycles and light motorcycles, which also have a sidecar (L3e or L4e), as well as trikes (L5e) or quads (L7e) that in on January 1, 1989.
• Tractors such as tractors or tractors that are used for agricultural and forestry purposes.
• Forklifts and other self-propelled machines, but which trucks do not resemble allowed. "back

Which vehicle has to go to the general inspection at a certain point in time?

Product presentation begin the deadlines for the HU and the AU always with the month and year of the last HU or the respective Year, at Seasonal license plates the situation is different. If the date for the HU falls within the "rest period" of the vehicle, the HU in the first month of the new operating period. If the HU were set for January, but the car cannot be used again until April, the HU right in April be performed.

To get a fine when returning to Germany avoid, you should be able to document that your vehicle has a valid HU decreed and since then no longer in Germany was. The best example are Campers & RVs to Rentwho have been on campsites abroad for a long time and therefore may no longer have a valid HU when they return. As proof of the stay abroad, e.g. B. Test reports from foreign test centers. In any case, the HU must compellingly when the vehicle returns to Germany made up for .
