One problem related to power door locks not working has been reported for the 2003 BMW 330. The most recently reported issues are listed below.
Please note that this incident happened prior to the date and mileage noted above as the previous owner had to also deal with this problem. I report the dates as when I received the car when it came into my ownership only. Driver's door lock failed to electronically and mechanically unlocked from the inside. The door can only be opened from the outside with a key. This poses a potentially grave safety concern as no one can open the door from inside - essentially passengers may become locked-in. Culprit appears to be BMW e46 gm v module factory coding where glitch prevents door locks from behaving appropriately. Aftermarket reprogramming fixes the issue. This is a very common issue for BMW e46 vehicles - internet search "BMW gm v control module" for details and testimonials. BMW should be held responsible and fix the issue.
