My car: Seat leon Fr 1.4tsi chpa , module- 5Q0 907 379 R

After installing used module and coding it, I can't cope with these three errors, I even bought another ABS module because I thought maybe the this one was also faulty, but I still get the B200F F0 error.

Tpms light on dashboard
esp light on dashboard


I scanned my car with VCDS and I have 3 errors, there were 4 of them. One was related to the steering angle sensor, but I did the adaptation and it disappeared. These 3 errors remain and nothing has changed on the dashboard.
internal disturbance - B200F F0
Data bus -U1123
Data bus - U1121
 
I did the basic settings and it shows completed correctly, after a while it says stopped and the errors do not disappear after doing this
 
How did you sort it in the end as im having the same problem with my 2009 1.9tdi Leon
I didn't solve it. It seems to me that the used modules simply weren't compatible with my car in some way, which is why the error kept appearing. -B200F F0 but i am not sure. A "no CAN communication" error is appearing on my original module; I found a company that repairs them and sent it off three days ago—they are supposed to call me to let me know if it can be fixed.
 
B200FF0 indicates that the module has an internal error with memory corruption or the checksum failed.

Check the coding and basic settings are definitely OK. Turn the steering lock to lock. If so, then I would suggest disconnecting the battery for at least couple of hours, and then seeing if the module reboots without that code. If you still get the same code then the unit probably needs replacing as the memory has a hard internal fault.
