Apparently in this model, per BMW, 75% of the gas is in one side of the gas tank, the other 25% is moved over when the tank has used the 75%. This is done by a computer chip. When the car was 1 year old, it died with 1/4 tank of gas while doing 55 mph on a highway with a car on my tail - almost got rear-ended. BMW replace the Fuel Pump - no change, it did it again at 1/4 tank of gas. BMW replaced fuel pump again, no change. This went on for over 1 year in and out of the shop leaving the car for weeks on end and BMW could not solve the problem. I asked them to check with headquarters to see if anyone else had this problem and was told each dealership tracks their own repairs, there is no major database listing all issues (hard to believe espcially in light of the need for recalls). I gave up finding a solution and now simply keep the car filled with gas and pray it dosn't happen again.

Has anyone had this problem?
When trying to start the car, it sounds like the starter clicks a few times and at the same time it seems like the electric goes on and off in synchronization with the starter clicks. The battery seems okay as all the electric works and the headlights are bright.

Hi, when I try to put the emergency lights on they don't work...when I push the lock button inside the car nothing happens...the keys also has a problem it's still working but is very delayed and sometimes after pressing to unlock or open the trunk it still wont go so I open it manually...I went to auto zone and they told me I needed to replace an electronic flasher (a cube piece that supposed to plug into something; tripdon ep-35 12.8v/ 182w max is what is says on it) So I'm
wondering if this is what's going to fix it and if so where does it go? If not please tell me way I need to fix it...thx in advance.

Today, the passenger window has stopped. I try to pull it up manually, but oddly, when I pull the up button position, it tries to lower the window. I want to pull the door panel, but am afraid of the airbag. WTF?
My 2003 BMW 325i is dying on me when i am driving the car, the check engine light is on and i also saw a timing light turned on once in my Dashboard.
