Far-reaching man-made atmospheric changes are looming on the horizon. They will have grave consequences for the earth’s biosphere unless we dramatically reduce and control the pollutant emissions of motor vehicles, among other things.

The On-Board Diagnosis System (or OBD) was introduced for this purpose. OBD is a diagnosis system integrated in the vehicle’s engine management system which continuously monitors the components affecting exhaust emissions. If a fault occurs, OBD recognizes it, stores it and indicates it via the self-diagnosis fault warning lamp (MIL).

OBD II is the second generation of engine management systems with diagnosis capability.
OBD II offers the following advantages over periodic vehicle checks:

  • l It checks pollutant emissions continuously,
  • l indicates malfunctions early, and
  • l provides full-fledged diagnosis functions which simplify troubleshooting and fault correction for workshop personnel.

In the long term, we will expand the capabilities of the diagnosis system to make it possible to detect faults in the exhaust system that are detrimental to emission behavior by means of a simple OBD reader, even during spot checks.

Self-Study Program No. 175 was developed and published specially for the U.S. market at that time.
On account of recent developments (launch of US Beetle model onto European market), we
have updated this SSP and included it in our Program under No. 175.

Important!
The Self-Study Program is not a Workshop Manual!
Please always refer to the relevant Service Literature for all inspection, adjustment and repair instructions.
