I have a 2001 e38 with a M62TU engine. I want to delete the Secondary Air system. Can this be done with NCS Expert? I have not been able to diagnose why i get a SES light every morning. I have been through the system and the pump works fine, the Valve seems to be ok, i have replaced the O rings on the crossover pipe, yet i still get a Code and SES light. I dont have emissions tests here in Alabama, so i'd just like to delete it. ALSO, can a EURO Tune be done on this engine as i saw you do on your E39? THANKS SO MUCH!
