My 328i just started to overheat in this summer heat and we cannot seem to find any problems with the cooling system ALTHOUGH there is no auxiliary fan sensor box mounted on the shroud and I can't remember if there ever was one. Can't even find a cable to run to the box either if there was one at any point, and this would explain the overheating if these sensors are supposed to be there.
Thanks, Dino
Ps part number for the aux fan sensor is 64118391470
