What to do if a tachograph fails: how to prepare a service request

First describe what the device is doing

In the event of a fault, the most precise description possible is helpful. State whether the tachograph shows a specific error, whether a card cannot be read, printing or data downloading does not work, or whether there is a power or communication problem.

What to send before your visit

• registration number and vehicle type
• tachograph type, if known
• text or photo of the error message
• when the problem appeared
• whether you need the vehicle returned to service as quickly as possible

Workshop service or mobile service

Some tasks require workshop equipment, while others can be handled by mobile service by arrangement. The service centre will confirm the appropriate procedure based on the fault description.
