I'm not here to teach English and not being pedantic but I'm not sure exactly what you mean, you lost me a bit at "while have to switch engine of green lights flashing while on petrol".

Do you mean you have to switch the engine off? If so to cure or work around what problem?

Do you mean it will never switch to LPG automatically? If so can you force it to switch to LPG?

The engine won’t switch between gas & petrol while driving .The engine has to physically be switched off it, while in petrol mode the round Brc switch on the dash the green lights on it flashes continuously but in gas mode they operate normally the taxi runs on Brc injectors and a genius 1500 vapouriser hope that’s a bit clearer to understand thanks
