Patrol to CNG switching issue

Hi,

My Car (Santro Club) has an issue regarding switching to CNG.
Some times it works fine for few hours or couple of days even but again it started creating problems.
When I start my car and switch it to CNG (no problem initially) but after driving couple of KMs, it gets stopped and I�ve to switch to patrol. After few moments when I again switch to CNG, some times it started working but some time it doesn�t switch; even I couldn�t hear the switching noise (a click noise).
I�ve visited some workshop and they advised that CNG kit needs to be serviced and Cylinder should be oil free. (So I did but the problem was still there.)
Then they recommended adding some relay onto CNG coil because it seems weak. (So I did but the problem was still there.)
Now electrician recommends changing the coil. (But I didn�t).
What do you guys suggest?

Observation: This problem occurs in hot weather too. I�ve faced this issue today but it was working fine since last couple of weeks because of less hot weather.

If the car is under warranty then get it changed from them....... if it's was an aftermarket kit installation even then it can be claimed if it's not an year old..........Waisay the original coil costs Rs.1000.

The problem as you have described it does point to the coil malfunctioning............. anyways people did point to the coil in your case...... when i was facing this issue people gave diagnostics like some safety valve malfunctioning and water circulation............ no one ever pointed to the coil.........
