Police raided a parts supplier of BMW Korea on Thursday as part of a probe into suspicions the Korean unit of the German carmaker covered up vehicle defects that led to dozens of engine fires in recent months.
The Seoul Metropolitan Police Agency sent investigators to the supplier's headquarters in the southern city of Yangsan and its research center near Seoul.
The company supplies exhaust gas recirculation coolers and pipes, which BMW blamed for more than 40 vehicle fires this year.
