Increased ECU flashing is necessary due to the trends in the Automotive Industry

The number of electronic control units in automobiles (automotive ECU, Electronic Control Units) has risen significantly in recent years, not least due to developments in electromobility and connectivity in autonomous driving.

Premium models currently rolling off the assembly line already contain up to 100 ECUs, which are subject to constant software updates. In some cases, the updates improve performance, but often they are security relevant and close existing gaps, similar to updates to operating systems of PCs or smartphones. Modern infotainment systems are also regularly provided with updates to ensure comfort and individual use in the best possible way.

The consequence of the increasing number of ECUs for manufacturers and suppliers: the requirements for up-to-date software and corresponding safety solutions are increasing.

Important criteria for the selection of a service provider for flash actions

  • Reliable partner
  • Licenses
  • Equipment
  • Professionals
  • Experience
  • Flexibility
  • Documentation

Procedure of a flash process


Control units have an electronically programmable flash memory that receives an update via a flash process. Each OEM has its own hardware and software components for this purpose with appropriate encryption to ensure the security of the transmission. The hardware is connected to the vehicle by cable, the program is started, and the information exchange starts. Programming the ECU includes diagnostics, the process itself and also the subsequent documentation.

Licenses and equipment

EuroQ is a tested and approved service provider for software updates at VW (ODIS) and Daimler (Xentry) and has the corresponding licenses and equipment. Numerous employees are appropriately qualified and authorized, so that we are able to implement far reaching flash actions at different locations.
