Hi, I just installed my active exhaust and reprogrammed the lines using forscan only changing the single digits on:

720-04-01: 0411 0002 0045( already had "4" coded)

720-10-01: E000 0000 0048 (changed from "D" to "E")

The actuators are turning when i power the car on and off, but I still get the "Exhaust selection not available error" and while engine is on the actuators move to the closed setting.

It's finicky I had the ability to change the setting once without recoding in forscan, but could only go from silent to normal and it was either closed or open. I was doing this before installing the mufflers and after install i simply turned it off and on and it's back to the error. Any help is greatly appreciated.
