Is the vehicle going into limp mode BECAUSE the fuse blew, or is the fuse blowing BECAUSE she is going into limp mode? Personally I would guess the former, and something the fuse is feeding is blowing the fuse. If that something is related to engine management (as Marc has said) the ECUs will, to protect the engine (and try to get you home) cause limp mode to happen.
I dont know what order its happening in. All i know is, after its gone into limp, i check the fuse and its blown. Cant see how i can find out the order of events.
That is why i was trying to find out what the fuse was so i could look at that circuit. Im guessing the same as you that it goes into limp after the fuse has blown. What i cannot confirm is if the fuse is linked to the frayed wire. The AA man said it was but only because it came up on his AA fault system as a "tip" to look for. But it has dropped into limp again after the insulation on the wire had been sorted and again the fuse was found to be blown so I'm guessing it cant be connected.
