Right then guys,after looking for a while for an e53 X5, i finally picked one up yesterday, its a 4.6is in estoril blue, bmw service history with 74k, was happy with it untill this morning. I drove the 3hr trip yesterday to go pick it up, the guy selling came to pick me up from the station in his work van so the car could be started from cold, when i got to his house the car hadnt been started for a few days and was covered in frost so obviously hadnt been driven or anything in the last 24hrs, but i pressed unlock, car opened, started and drove fine, everything working as it should, finally settled on price so came home with it. However my lil one was having a play last night and pressing buttons etc (i wasnt in the car, the wife was letting her), ive come to it this morning and was completely dead, central locking not working and very faint dash lights, my dad popped over and jumpstarted it using the points recommended by the manual in the engine bay, fired up straight away and drives fine, however ive lost my central locking on the key and the button inside, have no interior lights, not even when doors are open, i have the orange glow from the downlights but nothing else, could it have blown a fuse or does it need plugging in?? The central locking works when locking/unlocking manually but not on the button, Any help would be much appreciated Thanks Daz
