It seems that your UTCOMP module is resetting every time you run the car. It seems to me that you have not connected +12V power from battery (pin A24) - only 12V from ignition and UTCOMP does not have power when you switch off. It has inside small super capacitors so it can work without power only few seconds, but when voltage drops it will reset and you will have "beep" at cold start. Just connect +12V BAT to A24 and it will be fine.
