Abstract - In this paper some problems concerning the European On Board Diagnostic System (EOBD) system applied in automotive vehicles examined in Poland for type approval and its level of implementation are discussed. The level of monitor realization during tests performed on a chassis dynamometer within the NEDC emission test as well as in real road conditions is described. The evaluation of emission test results (CO, HC, NOx, CO2, PM) obtained during type approval tests in 2003 is presented as well.
