Our Team


dario e davide mangili

.... Many things can be done alone, but you will never be able to do all what a "team" can give you ... Sharing ideas, enthusiasms and passions is the only way to reach all those people that you would never have had the chance of or know by yourself. I thank all of these " travel friends" because without them this project could not have been born.
The entry into force of the EC Directives 715/2007 and 692/2008 date back to 30/06/2010.
Since then we started working with pass-thru protocols, when this term (pass-thru) was still unknown by the majority of car repairers and even by manufacturers of generic diagnostic instruments.
33 years of experience in the world of generic diagnosis and almost 10 years of experience in this delicate sector are our

business card.
