Recently parted out my 2016 M235i and have this great plug & play amp for sale. Amp is 3 years old and in perfect working condition. I left my tune installed as well so you can start off with something.
I will include an ASD delete harness for no extra charge which is recommended as well as a long USB cable for tuning.
To see if your BMW will work with this amp, use this link and type in your VIN.
