I will try it. Thanks

Petrolhead, I spoke with my LPG mechanic and he says that I do have the manual valve but also an electronic valve. He is sure that it can't leak gas so I didn't try it at this time (but probably will as soon as I get the chance because it is hard to get to).

I did replace ALL ignition coils and the car seems to be starting better but not perfect as it should. However, my wife tried to start the car with her key and it wouldn't start at all couple of times she tried and finally it did the third time. I found another thread that points to EWS or faulty ignition switch. Could this be it? Or is it something else?

I also replaced the battery with another one that was recently charged (before replacing coils and there was no change in how the car starts).

this was another issue I had on my X5 when I got it. You could fix that for fun if you haven't already.
