Problem with electrics on E39

[off_again]

Not sure what is going on, but a few times now the car will cut out, the hazard warning lights will come on and the interior lights too. Stop, lock it, unlock it and its fine again. Any suggestions as to what is going on?

Thanks in advance - oh, its an E39 535i

flog it...

Now that's helpful ....

Actually, we are seeing how long it lasts before something nasty goes wrong. Worth £1k of new money so bit of a bargain banger so need to be realistic. However, did a bit of Googling last night and it appears that the ignition barrel seems to be the most likely problem area. Anyone know how easy it is to get the part and replace it?
