Have your car's fault memory read – reliable service at your Bosch Car Service nearby

The fault memory of a car is a key component of modern vehicle electronics. Its primary function is to detect, record, and provide diagnostic information about malfunctions and issues in the vehicle’s various electronic systems.

Sensors and control units continuously monitor the car's functions. When an issue occurs, it is detected and stored in the fault memory. Details such as the car diagnostic codes, the affected system or component, the environmental conditions at the time of the error and the frequency of occurrence are documented.

Our experts at Bosch Car Service can read the fault memory across all vehicle brands and models using Bosch's professional diagnostic tools (OBD tool) to quickly identify the exact issue.
