pm me price for the jb4 pnp with usb cable for 08 335i e93 shipped to 15122...
is there anyway you can upload the latest software if i purchase your JB4? since i dont have a net book currently?
Once the USB cable is installed there is no need to open the ECU up to flash the new firmware or read codes. All done through the USB. Just route into the glovebox.
