my car has been in the shop since last thursday and up to now the mechanic hasnt figuere out whats wrong with the car. he told me that it might be the cumputer because the EWS and NDE are fine. If the computer is bad, how much could it cost? please help.

Just curious, where did you take it?

That doesn't sound right. You should have good success here. San Leandro Auto BMW Service - San Leandro, CA

Check to see it your A/C or heater is still blowing when you turn off the car. If thats the case then that is causing the battery to die. I had this problem and all you got to do is change the final stage resistor blower. BMW came out with an upgraded part to fix this issue.

This is the same part that I am talking about in post #9.
Omar, I'm willing to bet that this is your issue. You have now spent more money trying to diagnose it then what this part actually costs. Replace it, and see what happens.

yup omar check on ebay the part sells for only $40 and let us know if this fixed your problem.

they found the problem, the EWS module went bad We just order it today cant waits to be behind the wheel again.
