My 530i 93 V8 problem is the check control displays lic.plate,tail,side,dip lights out all at the same time when i switch on and sometimes after 10mins-1hour? The other problem is in the fuse box i do not have a mustard relay in place of this item there is a shot green relay? I have swaped the LKM with the one in my 735i 89 and all was fine for about a week then all lights reporting out but no light problems on inspection? the 5 lkm went into the 7 and has worked fine now for about 2 months? Is there an earthing problem? or something else i should check?
