Can we add a howto on glow plugs and the controller?
I just did it on my x5 35d, which is similar.

Some pointers that should be emphasized:
-Warm up engine before removing the intake manifold to prevent the plugs from breaking in the head!
-Make sure you feel the connectors for the gp controller click in.
-After that, don't start the engine, but key in- ignition on- scan for codes and clear them and scan again. Of course there will be codes for things disconnected BUT make sure you don't see any glow plug codes to confirm that your installation is correct- if so, then you can go and put the intake manifold, etc back! (in other threads I read cases where poor souls had to remove the intake again due to a bad connection to the controller!)
