Just picked up another 523i Touring after losing the rear of my last one on a damp iron inspection cover and having it written off!
This one has a dead Cigar lighter socket. Due to assuming 'Charger socket' was cigar lighter and fuse 39 being intact, I have stripped down the centre cosole to inspect socket. Now have realised with help from Haynes manual that 30A Fuse 52 in boot is appropriate fuse; with cigar lighter unplugged from the loom, the replacement fuse also blows immediately. Does anyone have any ideas? or shall I start to remove more trim to trace a short?
