Ultegra Di2 Front Derailleur not going into adjustment mode
Wonder if anyone can help me, or has had a similar problem.
I have a 6870 front derailleur that doesn't want to go into micro adjustment mode, when I click either of the left shifters (having pushed the button on junction A) it doesn't micro adjust, the red light just flashes on the junction box.
I can't find any thing in the documentation, nor anywhere on the web, about the junction light flashing or an error or anything.
Otherwise it all works and shifts fine. Strange! It also had been micro adjusting fine up until yesterday too.
Anyone had any similar problems?
