Spark plugs are new, ignition coil I don't know yet, injectors dunno... Fault code was P1633 Throttle Adaptation. The code is what Platte Forme based their guess on.

Battery is new. The light problem is hard to describe. Unrelated I think.

I didn't know that actually. The BMW dealer here in town can be a bit hard to work with. I bet that will cost me $200 at least for them to tell me that.
Thanks for all the help guys! It's arrived in the city, just waiting to pick it up til Monday.
