My code reader is throwing an E-Box fan fault code 2F71. From everything I read, it's not a terribly difficult replacement to DIY in general. But on my 2008 E70, however, I cannot seem to find the E-Box to get started! Anyone have a goo description of the best way to do this (and any pics)?

In the NE it's 80+ outside each day. With the fan not operating (I assume this..maybe it's the fuse?), am I putting the control unit(s) in significant danger (as in I should go to the dealer and buy the part immediately) or can I order one <cheaper> online and wait a week to do it and still drive in these 80-90 outdoor temps?
