What is EOBD?
EOBD is an abbreviation of European On-Board Diagnostics.
Since 1 Jan 2001 All petrol cars sold within Europe, and diesel cars manufactured from 2003, must have on-board diagnostic systems to monitor engine emissions.
These systems were introduced in line with European Directive 98/69/EC to monitor and reduce emissions from cars.
All such cars must also have a standard EOBD diagnostic socket that provides access to this system.
