C7 A7 ACC fault.
Hi
Lately I've been getting ACC and Braking guard not available messages after engine start. Happens every day on first start. If I restart the car after driving for half an hour then ACC works again. I've also tried after 5min but it needs longer to start working. Started getting issues when temperatures got a bit colder, was working fine all summer. Ran a scan and got codes U023500 Lost Communication With-Cruise Control Front Distance Range Sensor and U107100 Automatic Distance Regulation 2 - No Communication. Any suggestions where to start from? Checked connectors for front bumper radars and both looked clean and dry.
