lpg light on vx dash

[lembo01]

I can not seem to get the LPG light to work when im running LPG on my car, the vehicle was factory fitted with dual fuel. A autoelectrican has looked at it and he can get the light to come on when he checks it, but he can not get it to work when i change over to LPG. Anyone got any suggestions.
The vehicle is a 2001 Holden COmmodore Exec wagon v6.

Thanks Jarred

I have the same prob on my vx, when doing the dashlight diagnostics via the trip computer controls,everything works, but it wont show when switched to lpg.
Do you have any other gremlins with the lpg system?, like not starting after an hour or so after being run, or trying to start it when its hot on lpg after running on petrol for a while.......which I have, which is possibly a problem with one of the little black boxes that control the system and the lpg light problem could be related? Ive learnt to live with mine rather than go chasing this prob which most likely would end up in $$ replacing items etc. ie change to lpg when the engine is running when its hot.
If you do find the problem, let me know.
