    Have you tried a new thermostat? Is the cooling fan operating properly?

    did you bleed it thoroughly?
    It takes a long time to bleed after draining the radiator, you need to take the bleed screw out along with the cap, fill radiator, when its full put radiator cap back on leaving screw out until all bubles are gone. its taken me 30 minutes to totaly bleed my 328i before, I saw my mechanic spend an hour bleeding a 745i before

    turn your heater on while bleeding it as well!

    I had the same problem with my 1998 328i. I replaced the thermostat and entire cooling system and didn't fix it. The I blew the engine as I got stuck in traffic one day - spent 5k on that. Spent close to 10k in repairs and still wasnt fixed even with new engine. Finally found a mechanic who replaced a little fuse (and charged me nothing). Never overheated again. Unbelievable! I don't know what kind or where the fuse was, but I remember he said a lot of mechanics don't kow about it. 5 years later - running great. And I'm in Phoneix now. When I was having the problems I was in Seattle.

    Where was the fuse, under the hood or under the dash? I have a heating problem and my water pump and radiator was
    replaced a few years back.

    Where is the fuse and what type of fuse did he put in. Do you know what the fuse is called? I have a 1997 BMW 328i
