Check your engine temp sensor/plug/wires..
Its located behind the oil filter housing on the Left Hand side of the cylinder head.If that was the problem wouldnt a error code come up or no..... but was thinkin that thats on the side of the motor bloody awful spot to get to.....

Sometimes they do sometimes don't..Just fiddle with it...Dissconnect /reconnect ..Because engine temp triggers the change over
Ok I have the same problem I have taken it to a LPG mechanic he originally thought a reduction temp sensor which is screwed ito the lpg converter / reducer which is located inside the inner guard on the front drivers side, once he had found his brc cable to plug into the lpg computer he found the fuel rail pressure was low when trying to switch to lpg, he figured it was the lpg converter worn outr apparently they only do about 100,000 KLM before needing to be rebuilt with a kit new seals rubbers etc. I asked him to order the converter solenoid temp sensor and filter, that's the last I heard from him so I have ordered the parts myself still got to get them fitted, bottom line better having the work done by a licenced lpg guy but be careful they will rip you off sooner than look at you.
I have only just see your post sorry for the late response what parts do you want the link for the lpg converter , solenoid cut off switch ? let me know and Ill post it
