Question about Vauxhall Cars & Trucks
I would say the battery warning light is in fact on, and the alternator is not charging the battery.
Problem could be the alternator, or something in the circuit between the alternator and the battery. Usually a faulty battery will not turn the warning light on but I would have the battery tested anyway.

the bcm should not drain the battery, make sure the battery does not have a bad cell in it this could cause the battery to run down without anything draining it.

alternator gone bad, 100%. as the voltage starts dropping, all the lights on the dash will go crazy because the electronics cannot perform their self diagnostics, as they do not have sufficient voltage.

okay do me a favor crank the car and then pull your positive battery terminal off the battery.
this will let you know if your alternator needs to be replaced if its not working then it will die in a min or two and that means your car has been running off just your battery and that is what has been draining it. hope this helps let me know good luck

The light does it say Water? You are sure about this? Please have this checked by a mechanic asap,. if it is starting to run hot if you catch it early then you can avoid serious damage to the engine. The smell may be a leaking engine water pump or other component of the engines cooling sytstem.
