The Tata Sierra has reportedly become the first model of its kind to receive an aftermarket CNG conversion, sparking widespread discussion across the auto community. A vendor identified as saifuelvadodara_2.0 has installed a EuropeGAS CNG kit made in Poland on the petrol naturally aspirated (NA) engine of the Tata Sierra.
However, despite the careful installation approach, technical issues surfaced even before the final test run. Reported problems include an odometer glitch, sunroof malfunction, and moonlight system errors.
These issues have raised serious questions about electronic compatibility, as modern vehicles rely heavily on interconnected ECUs and sensors. Even without wire cutting, aftermarket kits can interfere with vehicle electronics if not perfectly calibrated.
This development has reignited the debate around safety and warranty concerns. While CNG conversions are popular in India due to lower running costs and reduced emissions, manufacturers typically do not approve aftermarket CNG kits for new-generation vehicles unless factory-fitted. As a result, such modifications can void the vehicle’s warranty, especially if electrical or engine-related faults are detected.

From a safety perspective, the quality of the CNG kit, installation expertise, and long-term reliability are critical. EuropeGAS is a known global brand, but real-world performance under Indian driving conditions remains to be seen.

The Sierra’s success as a CNG vehicle will depend on how well these early issues are resolved and whether the vehicle delivers consistent performance without recurring faults.
As this appears to be the first Tata Sierra converted to CNG, it remains an experimental case. Whether it sets a trend or serves as a cautionary example will become clear only after extended road testing and real-world usage.
