Hi all,

Yesterday my Di2 Dura Ace 9100 Front derailleur auto trim stopped working?

It shifts perfectly fine from small to big ring and vice versa, but does not do the automatic micro adjustment and therefore I'm getting chain rub when in the largest and smallest cogs of cassette.

Battery is fully charged.

Also the small manual trim via the small lever isn't working either. Assume this is connected to the auto rtim issue though.

Any help is much appreciated.

Thanks,
Simon
