I have wagon R lxi 2011 k series retrofit with sequential Tomasseto CNG kit from a authorized Centre
around 15 months back.
First 12 months were good no problem at all around 20,000 km done. But since 3 months there has been a jump from CNG to petrol with the CNG light keeps blinking in the switch.This occurs specifically in city traffic. And problem sometimes occurs several times a day and sometimes no problem for 3-4 days straight.
Several authorized centers failed to diagnose the problem though on running diagnostic with laptop it shows faulty injectors, Tried with changing the injectors of cng but the problem remains the same and even with new compatible injectors laptop diagnostics shows faulty injectors.
Every other CNG fittment center tells a different fault.
One wants to change injectors which I agreed but didn't resolve the problem.
Second one says its faulty ecm, third one says its fault of plug in reducer, third one says its timing advancer failure.
No one gives a guaranteed solution.
Please help

Though its not possible to remote diagnose in the issue, but for the blinking CNG Light - effectively means that CNG is not switched over- suggest to check out

> CNG Kit Wiring - it may likely be possible that the wiring connection has turned loose at any of the end
> Resetting in Sequential Kit ECU and Sensor - effectively known as Tuning

May likely assist in resolving the issue !!
