Do you have a error message, if so what is it?
No

Did you update the APIM config so that it knows there a TCU?

Now the whole conference is correct, maybe it’s such that the problem is in Gwm I installed it from a new car, with support Hs4

For HS4 you would need to add wiring to the APIM and have an APIM that supports HS4.

Your vehicle doesn’t support HS4. You need to use HS3 and downgrade the TCU to J-series firmware.
