is there an aftermarket software to reflash the ECU.???using your laptop or a snap on scanner. bmw has learn the hard way that sometimes because a code comes on that replacing all the parts related to that specific code doesn't fix it in this case the famous code p2096 which crosses over to bmw code 235
the only real fix is to reflashing the ECU fixes the problem. this info come from bmw tech in DARIEN CT. where i deliver oil to them.
thanks
