Very Interesting Thread. I'm in the process of changing the glow plugs in my 240D and I figured I would attempt to do so with the injector hard lines in place, but decided other wise. The car has been sitting under cover over the winter and when I was working on it last it was 40F outside. The nuts on the hard lines are unwilling to budge, though I haven't used the breaker bar as of yet. I am curious though if I would be better off firing up the engine to warm it up before trying to remove the hard lines and glow plugs.

Would having the engine warm make removing these various items easier?
