Precision Troubleshooting
Common CNG Issue Expert Repairs
We use computerized software scanners and calibrated diagnostic gauges to solve complex CNG problems.
Gas Smell & Leakage
Pungent CNG smell around the car or engine bay indicates leaking high-pressure ferrule joints or aged rubber hose degradation.
Engine Misfire / Jerking
Vehicle jerks heavily while accelerating on CNG mode due to ignition mismatch or incorrect spark plug gap setting.
Low Fuel Mileage
Sub-optimal average per kg gas driven, caused by clogged gas rail injectors or uncalibrated reducer output pressure.
CNG Not Switching / Flashing
Dashboard switch continuously flashes green/red or keeps beeping, preventing the car from switching over from petrol.
Power Loss / Pickup Lag
Sluggish acceleration, sluggish incline climbing, or engine turning off when AC is turned on in CNG mode.
Reducer Pressure Issue
Hard rubber diaphragm aging causes improper gas flow, pressure drops, or gas overflow into intake manifold.

Frequently Asked Questions
We recommend servicing your CNG kit every 10,000 km or along with your regular engine oil change. This includes replacing the low & high pressure gas filters and checking for minor leaks.
A flashing or beeping switch indicates that the CNG ECU detected a fault (e.g., low gas temperature, faulty MAP sensor, or pressure drop). Connecting an ECU diagnostic scanner will identify the exact error code.
Yes. Government safety regulations mandate CNG cylinder hydrostatic testing every 3 years. Driving without a valid hydro test certificate can result in traffic fines and pump refilling rejection.
CNG requires higher spark energy to ignite than petrol. Worn spark plugs, weak ignition coils, or improper ECU map tuning are the primary reasons for vehicle jerking and pickup loss.
Minor leak fixes and ECU tuning take approximately 30-45 minutes. Reducer overhaul or injector jet cleaning takes about 1.5 to 2 hours.
