E38 bonnet / hood release cable fail
The cable to release the bonnet (hood!) came away from the mechanism on this E38 750iL. The usual recommendation is to buy a new mechanism which will cost about £50/$80. In this case though I disassembled the unit and managed to re-secure the cable, then re-greased everything. It never failed again as long as I owned the car, so always worth checking for the simple fix!
