my 325 e is out of commission right now and i dont know where to start. it doesnt look like the pump is leaking. could it be the gear box? if it was just a slow leak i wouldnt worry about it, but within a 4 hour period all of the fluid is gone. i dont know to much about this car but if i did pin-point the problem i could fix it. i can be more spesfic if yall can point me in the right direction. thanks- will
