@VipinLJ ,
Two ideas for your consideration:
• You can get an OBDII scanner. I have OBDLink MX+ for coding, along with Bimmercode-- it's OK. The scanner comes with an App that can read & clear codes.
• You can get a copy of ISTA/D. Probably best is to go to the Bimmerfest forums-- but am not sure if that works on G20s?
Hope that helps
