Passion innovates future


From the standard family car diagnostics to telemetric data in Formula 1 racing – the electronic analysis of motor data – or vehicle diagnostics in brief – determines the daily routine of the automotive service industry. The developments of AVL DITEST, the Austrian experts in vehicle testing equipment founded in 1999, are said to set the engineering standard in Europe. Renowned vehicle manufacturers, such as VW, BMW, Jaguar Land Rover or the Daimler Group place their trust in the technical know-how from Graz. The important business fields of AVL DITEST in addition to vehicle diagnostics, are measurement engineering and exhaust gas analysis. Reference is made in this context to customers such as the European vehicle inspection organizations TÜV and DEKRA and their Japanese counterpart NAVI. Very early on in its history, this AVL Group company became a pioneer in high-voltage measurement engineering for safe work on electric and hybrid vehicles; defining the state of technology with its HV Safety 2000.



AVL DITEST equips garages and motor vehicle inspection centers with upmarket test systems and diagnostic equipment. Our corporate philosophy is based on our claim for technological and quality leadership, perfect service and global presence. The success of our products in over 50 countries is proof of the consistent implementation of our philosophy.

In Europe, the developments of the Austrian and German vehicle diagnostics and measurement technology specialist are setting the technological benchmark. Testing organisations such as Dekra or TÜV and big-name motor manufacturers such as VW, BMW, Jaguar Land Rover, Daimler Group and the Austrian motorcycle manufacturer KTM rely upon technical expertise from Graz and Cadolzburg. E-mobility, vehicle diagnostics, measurement technology, climate control servicing and emissions testing are the key business areas of AVL DiTEST.

AVL DITEST, founded in 1999, is a company of the AVL Group, the world's largest privately owned enterprise engaged in the development of engines, measurement and testing systems that can draw on automotive engineering know-how from more than 50 years of development work.


All AVL DiTEST employees are united by their strong commitment to making the needs of the customer the focus of everything we do.

Our motivation is founded on self-determination. We strongly believe that our technical expertise and character allow us to blaze a trail of our own. This is something we also want to demonstrate to others, and our customers give us the best opportunity to do so.

We are proud of our exceptional level of knowledge, our outstanding ability to solve problems and our pioneering spirit. We want to demonstrate these qualities to our customers and colleagues, which is why we are willing to step outside our comfort zone time and time again, putting our all into everything we do. We live for the adventure of discovery.

We are proud to work in a team of exceptionally talented people and see ourselves as part of the winning team. We want customers to think of us as the best. To achieve this, we never give up, even when this means going above and beyond.

We know that we can trust and rely on our colleagues, superiors and employees. This trust gives us the security and confidence we need to address the greatest challenges for our customers. Entrepreneurial spirit of this kind requires a willingness to take risks. The concept of 'blame' in this context does not exist in our company.
