[550Eric]

I have a 2008 BMW 550i E60 N62BA m sports package does anybody know what happens when reflashing a bmw computer how much does it cost??

Approximately 2-300$, depends on what module or whether you use dealer or indy, or having BMW tool suite and a reliable power supply can do it yourself as I have done.

Also found this in my files saved:
ECU Programming instructional:

You will not need the old ZB#, you will only need the ZB# from the module
you want to update. I
will give you a short instructions on how I use WinKfp to program my modules.
1. Go into INPA and print off the complete UIF page with ZB# and programming info.
2. Close INPA completely and launch WinKFP.
3. I use comfort mode since it does everything that I need it to do.
4. Once you are in comfort mode, Click on Choose ZUSB and make sure that the programming data is
loaded in there. If you dont have any data in there you will need to load it before you proceed to the next
step.
5. Close the window that is showing the programming data and click on Enter Vin, Enter your complete
VIN # of the car you are programming, and click OK, Vin will show up at the top of the program if it
accepted it.
6. Click on Enter ZUSB and enter the ZB# from the UIF printoff from INPA, and click ok.
7. It should load the next window and show the module # and something in the right screen. You can
leave those as default and click ok.
8. Click on Done, which will bring you to the programming page.
9. Make sure you car is hooked up to a battery charger(better yet a power supply at least providing 50 amps)
before you start the programming.
10. Once you have everything good to go click on program and sit back and relax, it will go through and
will say " You have 1 time left to program this ECU" click OK and it will flash it.

fyi....INPA and WINKFP are two of the programs included in the BMW tools suite mentioned, you can also do this with ISTA but am not familiar with it.
