Overview

Kraftfahrzeug-Überwachungsorganisation freiberuflicher Kfz-Sachverständiger e. V. (KÜS) is a German vehicle inspection organisation headquartered in Losheim am See in the Saarland. It is a registered association (eingetragener Verein) that brings together freelance motor-vehicle experts and inspection engineers, and it operates as one of the officially recognised organisations authorised to carry out statutory vehicle inspections in Germany. Its core business is the periodic roadworthiness inspection (Hauptuntersuchung, HU) including the examination of the engine management and exhaust emission control system, which is documented by a valid inspection sticker on the vehicle's licence plate. According to the German Wikipedia entry, around 1,500 inspection engineers work for KÜS, performing roughly 3.8 million official vehicle inspections nationwide each year, of which more than 3 million are Hauptuntersuchung inspections including emission-related checks. In 2015 the organisation's share of vehicle monitoring in Germany was 10.2 percent. This places KÜS alongside DEKRA, GTÜ and TÜV as one of the principal providers of statutory vehicle inspection services in the German market. Beyond the official inspection business, KÜS offers a broad portfolio of services. Under KÜS Automotive it provides damage reports and evidence-preservation appraisals, technical expert opinions, appraisals for leasing and rental returns, and valuations for historic vehicles. KÜS Akademie handles training and further education. KÜS Technik provides technical services. KÜS Data operates a data centre and IT services, including managed services, backup management, virtual servers, web hosting and domain administration for business customers. KÜS Service supports KÜS partners and external clients in areas such as occupational safety, occupational medicine, environmental protection, fire protection and the inspection of electrical installations. The organisation also engages in research and development. Its KÜS Drive project addresses the future of vehicle monitoring in the context of driver assistance systems, automated driving functions and vehicle safety technologies. The KÜS website presents the organisation as a strong association that thinks about safety holistically, offering a comprehensive range of services from a single source. Its stated mission is 'Drive safe. Ihre Sicherheit ist unser Auftrag' (Drive safe. Your safety is our mission). KÜS operates through a nationwide network of partners and inspection locations. Its business customers can access IT solutions, operational safety services and fire protection consulting. The organisation is active in the German market and is structured as a registered association rather than a listed company, with its federal office in Losheim am See.

History

Kraftfahrzeug-Überwachungsorganisation freiberuflicher Kfz-Sachverständiger e. V. (KÜS) is a German vehicle inspection organisation based in Losheim am See, Saarland. It is constituted as a registered association (eingetragener Verein), a legal form that reflects its origins as a cooperative body of freelance motor-vehicle experts rather than a conventional corporation. The organisation's federal office (Bundesgeschäftsstelle) is located in Losheim am See. The core of KÜS's activity is the performance of official vehicle inspections on behalf of the German state. Under § 29 of the Straßenverkehrs-Zulassungs-Ordnung (StVZO), vehicles registered in Germany must undergo periodic roadworthiness testing, the Hauptuntersuchung (HU), which includes examination of the engine management and exhaust emission control system. KÜS is one of the officially recognised inspection organisations authorised to carry out these tests, alongside DEKRA, GTÜ and TÜV. A successful inspection is documented by a valid sticker (Plakette) affixed to the vehicle's licence plate. According to the German Wikipedia entry, approximately 1,500 inspection engineers work for KÜS, conducting around 3.8 million official vehicle inspections nationwide each year. More than 3 million of these are Hauptuntersuchung inspections including emission-related checks. In 2015, KÜS held a 10.2 percent share of vehicle monitoring in Germany. These figures indicate that KÜS is a significant participant in the German vehicle inspection market, though smaller than the largest providers. Over time, KÜS has expanded beyond the statutory inspection business into a broader service portfolio. The organisation now encompasses several divisions. KÜS Automotive covers the work of motor-vehicle experts, including damage reports and evidence-preservation appraisals, technical expert opinions, appraisals for leasing and rental returns, and valuations for historic vehicles. KÜS Akademie provides training and further education. KÜS Technik delivers technical services. KÜS Data operates a data centre and offers IT services to business customers, including managed services, backup management, virtual servers, web hosting and domain administration. KÜS Service supports KÜS partners and external customers in areas such as occupational safety, occupational medicine, environmental protection, fire protection and the inspection of electrical installations. The range of official inspection tasks performed by KÜS extends beyond the routine Hauptuntersuchung. The organisation carries out modification acceptance inspections under § 19.3 StVZO, classification of historic vehicles under § 23 StVZO, inspections under the ADR agreement for the international carriage of dangerous goods by road, inspections under §§ 41 and 42 of the BO-Kraft (the regulation governing the operation of motor vehicles for the carriage of goods), inspections under the 9th exemption regulation to the StVZO (the so-called '100 km/h sticker'), gas system installation inspections (GSP) and recurring gas system inspections (GWP) under § 41a StVZO, and inspections under § 5 of the Fahrzeug-Zulassungsverordnung (FZV). In recent years, KÜS has also engaged in research and development. The KÜS Drive project is described on the organisation's website as a research and development project intended to ensure that vehicle monitoring keeps pace with technologies such as brake and lane-keeping assistants, occupant and driver information systems, lighting and visibility assistants, automation functions and assisted driving. This reflects the broader challenge facing inspection organisations as vehicles become increasingly automated and software-defined. The KÜS website presents the organisation under the motto 'Drive safe. Ihre Sicherheit ist unser Auftrag' (Drive safe. Your safety is our mission) and describes it as a strong association that thinks about safety holistically, offering a comprehensive range of services from a single source. The site provides a location search for finding KÜS partners, a facility for requesting report copies, online calculators and a partner login. The organisation also maintains a news section covering seasonal safety topics, motorsport involvement and personnel developments.
