On my last Zwift-session I had some problems activating ERG mode.
The trainer made a strange noise, see video here: https://www.dropbox.com/s/om7wjkqbe5eke ... e.MOV?dl=0
With disabled ERG-mode shifting and resistance was kind of ok, lower gear -> less watts and higher gear -> higher watts and no strange noise even though I could not adjust resistance.
Any thoughts on what can be done? Parts in need of service or replacement?
