Does anyone own a Canyon?

Thanks @amey and @Smallfurry. The Art's Cyclery vid was my first port of call after the techdoc, and I thought a full charge would do the job - a good shout though re a loose cable.

I thought perhaps plugging it into a laptop with some Shimano software would diagnose the problem..I just nipped into the LBS by work and they don't have it. Hoping Condor might be able to help.
