How do you change glow plugs on a BMW 530d?

I have diesel 86' 524td that I changed the glow plugs on. They run the length of the engine kind of like spark plugs. There are (is) probably six of them. They are smaller than spark plugs and have a wire on top of each one. Be carefull, the wire is held on by a small nut. Take that off first, then the glow plug. For the plug itself you'll need a deep socket like a spark plug socket only smaller. The ones in the front will be easier than the back because of wiring or accessories. Here's a tip from experience. Replace ALL of them at once. It will save you aggrevation in the long run from changing one or two now and later. Good luck. rich c.
