Therein lies the problem. With the new VO, you have to default code the MDSC, KOMBI, CIC - possibly NFRM and CAS as well just to fully remove any trace of EDC.
The additional changes you mention will automatically be done if it's coded this way, instead of only coding them off manually. Your method has left some configuration in the car that EDC is installed, but it is simply not reporting any errors to the driver.
You're welcome for the lesson
