Consumer Description

2003 BMW X5 CCV "OIL SEPARATOR VALVE" HAS ISSUES IN COLD WEATHER AND IS KNOWN TO FAIL. THE PROBLEM RELATES TO A NON PROPER DESIGN WHERE THE VALVE CAN FREEZE. THE ENGINE BLOCK CAN THEN BLOW OIL AND CAUSE FIRE. BEFORE IT BLOWS THE BLOCK THE ENGINE WILL HAVE "HARD STARTS" WHICH WILL PUSH FROZEN OIL THROUGH THE SEPARATOR. IF THE CCV FAILS IT WILL COMPLETELY BLOW YOUR ENGINE GASKETS. THIS IS A KNOWN ISSUE AND THEIR IS A BMW X5 SERVICE BULLETIN THAT THIS SHOULD BE LOOKED AT. BMW WILL NOT ADDRESS THE ISSUE UNTIL IT BLOWS. IT IS A MAJOR MALFUNCTION THAT IS NOT ONLY EXPENSIVE TO FIX WELL OVER THE 3000 BUT VERY DANGEROUS. I THINK AN INVESTIGATION INTO THE BMW PROBLEM SHOULD BE LOOKED CLOSELY. *TR
