Drivetrain Malfunction - Only in Eco and Comfort

I have a 13 328i n20 xdrive that throws a drivetrain malfunction only when driving in Ecopro and Comfort modes. If it's in Sport, never throws the code. I don't remember the codes off the top of my head but I recall them being a Vanos and boost pressure errors from a previous scan. Does anyone have any thoughts? I can easily get the malfunction to come back on and get the exact codes. Had timing chain replaced at 90k. Currently has 105k. Just don't want to keep blowing through tanks of gas constantly driving in Sport mode.
