hi i have done some research on these codes. i know it involves the BCM. anyways, i found a BCM for cheap. how much would it cost me to get it installed and get my car reconfigured? also how big of a deal is this problem? thanks

 

Not sure what you mean by "reconfigured".

You would have to buy the BCM that works with your model year.
Call the dealer to see what the install charges are.
It shouldn't be that difficult, it's mounted behind the drivers side kick panel. Couple of screws, couple of connectors to plug.

 

i have an 03 350z enthusiast and there's a guy selling a bcm pulled out from an 03 350z would it work on mine???

 

Check out this page, you can see the part numbers and model years covered by them:
