2003 328 computer failure
I have a junk car. It's name is BMW 328 built in 2003. It has only 25000 miles in it, but has not been stopping giving me problems since the first month I got it. At the very first month in 2003, the battery drained out everytime I didn't turn all of the electric equipment (Radio, AC...) off when I turned off the car. And the latest I got was the Altenator. I got to replace a new one because it does no longer work after only 4 years old. Now, 2 months later, the light shows that the driver door is open, although it is not..!!! I can't lock it using my key and have to lock and open all of the door manually. That sucks!!! Any one have seen this issue? I can't post what else I have got with the computer system as it will take me 2 days to finish my complains. I am just so sick and tired of this. I my self is a german engineer, very ashamed to say that the german can no longer built a reliable car.
Does anyone see this issue before and have a better idea what is the easy fix for this? I know I can bring it to dealer, but I am sick and tired to pay those blood suckers. It is their car problem, not mine.
