Engine malfunction lamp

Hello friends, about 3 months ago, there was a hole in the fuel hose and it was getting air, but we fixed the problem in the morning. If I connect it to the computer and delete it, will the problem be solved ???

Start, look what's wrong. If there is lpg, it burns normally

My car is not LPG 206 HDI 1.4 I think when the diesel is not gone, it does not solve the fault lamp.
