Consumer Description

FAILURE OF CRANKCASE VENTILATION VALVE IN 2004 3 SERIES BMW. THIS FAILURE WAS CAUSED BY MOISTURE BUILD UP IN THE VALVE, WHICH THEN FROZE AT AN EXTREMELY COLD TEMPERATURE, CAUSING THE ENGINE TO SEIZE. APPARENTLY, BMW HAS KNOWN ABOUT THIS PROBLEM, AS THE REPLACEMENT VALVE IS "RE-ENGINEERED". APPARENTLY, THIS PROBLEM ONLY OCCURS IN THE SIX CYLINDER ENGINE, AT EXTREMELY LOW TEMPERATURE, AND IN CARS WHICH ARE USED ONLY IN "SHORT TRIPS". THE CAR HAS BEEN DOWN FOR OVER TWO WEEKS, AWAITING PARTS. *NM
