Hi, I have a Jan 2008 Z4 The roof won't go up or down and I fear the hydraulic pump might need replacing: looking for someone in Devon who might sort it for me. Today I find the button serving the bootlid won't activate the mechanism: I have located the fuses but find there is a card identifying which fuse serves what but I can't undertand the card for there is a list of letters & numbers none of which I can understand: is there anywhere I can access a printout listing the actual elements relating to the individual fuses?
