I have a 2014 Z4 35i and have heard that there are some problems with the Cobb AP since the ECU supposedly has 128bit encryption which is different for the 2013 model.
Can somebody shed some light on this? Will I have to wait for a 2014 version of the Cobb tune?
I spoke with Cobb and they said no problem - the 2013 version will work with the 2014 Z4 ECU.
