We speak the language of the workshops. Our hotline, specially set up for you and manned by more than 50 qualified master car mechanics, is a fast and expert source of help for all your queries about fault diagnosis. We answer more than 500,000 international calls every year. And our Technical Centre offers you support with the evaluation of all data. Our comprehensive diagnostics and repair database is a veritable treasure trove of repair aids, possible solutions and technical data for over 35,000 vehicles. In addition, extensive technical services are available online, e.g. the workshop portal HELLA TECH WORLD.
