I have 2001 525i and had white smoke coming through the vents and replaced the vcg a second time within 6months. First time I changed it myself but still noticed the smoke comin out of the front grill andthrough the vents. So I went to an indie and they replaced it. They did a great job. Noticed it drove a lot better but I still have smoke coming through. When I popped the hood I noticed the smoke is thicker by the passenger side of vcg where the o2 sensors are. Now if I drive like a grandma there is no smoke or smell through vents. At complete stops the smoke come through the vents when accelerating hard. Does anyone know what is causing this? The smell is gettin unbearable. Have to drive with windows open and u can see smoke comin out the sun roof.
