Clicking/knocking sound Bosch CX Gen 4 motor

[wimvl]

I've got the exact same issue as the OP..
Click at 7 o'clock crank position. Motor bracket bolts are torqued.

Cannot reproduce it when motor is powered off..
(even when standing on the bike).

Tried with clipless pedals, rotating the crank with one leg only -> click is there (both left and right leg)..

19000kms bosch gen 4 speed 2021..

Anybody managed to solve this mystery? It does not really bother me that much but I want the motor to be reliable..

I had exactly the same problem on the same motor. I spent a lot of time trying to fix the problem. Did everything. Then one day the problem went away. I was left thinking that perhaps it was my riding boot clicking
