Installing brc sequent 24. So far it has worked without any problems. The symptom is that when driving on LPG the red and left green lights suddenly turn on (even when the tank is full) and blink. There is no sound signal for switching to petrol, so I am not sure if it is switching to petrol. Anyway, when I press the switch it will switch to gasoline and if I press again it will switch to LPG normally. The problem occurs randomly, with no indication of any particular engine operating condition. I searched the network for error codes signaled by a switch, but nothing fits my case. I am asking for some hint.
