Third motor and after 750 km is grinding sound back, but much quieter and less frequently as here Grinding rattling sound but noticable. This happens when i reach speed limit and watts produced by motor are around 10-40 watts.
I checked S/N and it is 74 xxx, model year '23. So little bit older...
New cables and display did not solve the problem, a new motor was needed.
In my case it is the second motor change, first time - grinding sound, second time - err 5401.
Hopefully 3rd motor will last much longer than a couple hundred km.
Next issue appeared yesterday, while walking next to my bike. Around 2k km, 500 km on new motor after waranty claim.
ERR 5401 DRV CONN, Communication error between Drive Unit and Display.
Visited LBS today, and they were unable to solve the issue, so TQ support was asked to help - advised...
Good news, motor changed, no grinding noise, no ticking and is little bit quieter.
New motor was produced on 24' and has S/N 116 xxx. The previous one was 10 xxx.
Unfortunately same issue here on Scott Solace Gravel(MY23), motor was produced on 22'.
After warranty claim waiting for new motor.
