Hi Guys, did F11 ACC retrofit, which worked for a bit untill new winsdcreen installed by owner. Now there is error.
On idrive: Front end collision warning and Cruise control restricted.
On diagnostics:  4827BF INTERFACE ACC

I tried removed kafas, and cleaned it and widnscreen, i also tried calibrating in ista and taken for a drive, but error comes back. 

Any ideas?

Was working for few weeks with kafas just lossely mounted to windcscreen. 

Acc radar works, stop/go works but not turning/ kafas functionality like HBA also not working.
