Summary:
1) Add option 3AC (trailer hitch) VO to your FA
2) Code the AHM: Connect => Read FA (VO) => Activate FA (VO) => Read SVT (VCM) => Left-Click on AHM ECU => Click on "Detect CAF for SWE" => Select the CAFD matching your I-Level => Select OK => Right-Click on AHM (the ECU itself not the underlying CAFD) => Select CODE.
I'm also looking at fitting the folding hitch to my 2014 F11 myself - are you able to share a scan of the supplied fitting instructions - and any tips once you've completed!
Thanks,
James
