Hello. My 1998 520i automatic is throwing black smoke from front grill on the bonnet, with burning smell. It happens only when car is hot. I go uphill to drop my son to school about 4 miles. From last one week I am noticing this smoke when reaching school and when I place hand next to grill its hot. But when I come back downhill back to home, no smoke, front of grill normal hot. I tried to check if there is problem with auxiliary fan, left the car with full AC on for half an hour. But nothing happened. AC is working fine however Auxiliary fan didnt turn on. Car is not over heating. Burning smell is like oil or grease burning
have the same problem?
