Hello Guys,
A while ago I retrofitted ASD from G01 to my 2014 F30 320iX
It was flashed and coded to my the newest software and now I'm can not change the sounds, it only works with F030 and N20B20 engine coded.
If I want to code another one, for example F080 and S55B30 or F010 and S63B44 - it just getting off the ASD and the error occurs in Rheingold.
I read that it is because of the new software and I need to flash the ASD with older psdzdata.
Then I got psdzdata 3.55 and flashed the ASD.
The result was like that:
It seems to me that it did not flash it properly is I got the same problem with disabling ASD when different engine coded as well.
Could you please help what I did wrong? Is there any special procedure when you downgrade the software from newest, or it is the same as you just flash the ECU's?
Thanks!!
