TMC2130 on MKS GEN 1.4, high pitch noise only on y axis

Hey guys :)
I am currently building a 3D Printer with much inspiration from that: [www.thingiverse.com]
However after a lot of troubleshooting I got most off it working, expect the y-motor is making a highpitch noise when it stands still.
I am running 5 Watterott TMC2130 on a MKS GEN 1.4 with Hardware SPI.

M122 Output:

I´ve tried everything: switching motors, connections, stepper. So I guess no Hardware problem?

I think, I setup something up wrong in the MarlinFW. So I tried different configurations but cant get this damn motor quit. :?

I have no idea what I could try anymore. I know there are some strange things in the M122 Output at Y, but I dont know what I have to tune to get it right.
Any Ideas?
