    No Idle

    I changed cooling system of my 323ci and now my engine will not idle. Before doing this my battery was completely dead so I replaced with a brand new one. I turn it on then it just dies out. Any help with this? Can it be the alternator or idle control valve?

    What parts of the cooling system were changed? Did you disconnect any electrical connectors? How was the car running prior to the cooling system work?

    Radiator, expansion tank & disa valve. No electrical connectors were removed just what was needed to replace the cooling system. Car ran fine prior to the change other than it smoking up from a hole in the radiator.

    Also turned on and drove before the battery died

    Is the fuel pump original? When was the fuel filter last changed? Google BMW E46 hidden OBC functions. Test #7 will show the voltage as seen by the engine computer (DME).

    Will check that. But I believe it is original the last owner doesn't have a reciept for that work being done. And the car has high mileage.

    Sometimes unrelated parts go bad at the same time. Coincidence.
