Hi Guys,

I have recently bought a Range Rover 3.9 V8 already
fitted with a open loop Star-gas LPG system fitted to
the car in 2000. The switch inside shows three
settings, B=petrol only, C=starts petrol then flicks
to gas there is also an L which is LPG only. I cant
get this setting to come on it will only rotate
between the C and B settings when I press the switch
to change. Can anyone tell me how I can get the L
setting to come up. Do I need to press and hold or
press it quickly so many times?

Thanks for you help
