Retrofit BMW Active Sound Design (ASD) with ISTA

Here is the tutorial on retrofitting Active Sound Design (ASD) to BMW F-series F30 328i MSport 2013 model.


The progress was tested on 328i. You are at your risk.

To start off with I ordered the module. It has various part numbers, but apparently they are all the same: 65129352264*; 65129326555; 65129343317; 65129353021; 65129362445; 65129362445; 65 12 9 322 712 (03/12 -> ); 65 12 9 302 536 (03/12 -> 07/13).*

I could not get a part number for the connector so I will be making up my own.

Next up I got the pin assignments from BMW ICOM A2 and ISTA Rheingold:



Here is the inside of the connector:



I then transposed all the pin assignments onto an image to make my life easier:



I then continued to only connect power and the CAN signal.

After this I flashed the ASD module. I used a modified FA where I changed the production code typekey to 3C17 to ensure it is a production code that included ASD.

Here is the FDL edit view afterward:



Next thing I must connect the feed from NBT head unit and output to the AMP. I first need to spend some time to make proper connectors so will update all you guys once I progress further.

Very excited to see this retrofit work!
