its happened to me twice one in the week and once today.

 

when i switch my car on, drive about then switch it off , i hear the fan go cooling everything down, either before, when the fan kicks in or just after my fuel pump starts. this carrys on until my battery goes flat, has anybody had any experiences of this or solutions????

1st thing to check would be the single wire that is located just above the injector rail that connects to a temp sensor. If the cable is damaged/disconnected etc. and it touches anything earthed the fan will run on even with the key out and car locked.
