I am having issues with the power supply to my radio. The radio doesn't turn on. i have replaced the radio unit and still the same problem i also replaced the display unit and still the same problem. now my front door looks are not working also. i was told it could be the PT module. Has anyone come across this problem? Does anyone know where the pt module is located on a 1996 740il ?

I know this sounds unrelated but i read about it on another E38 site. Remove the ign switch and wash it (a lot) in a bath of switch cleaner until you are bored - then do it for twice as long again. Then apply switch lube and re-install. Should make it all work again.
PS The diagnostics will probably tell you to check/change a relay in the boot - not going to help.
