i have the rxi FF CNG version. believe me the parts of this car are damm expensive.
last month my car started giveng jerks on cng, upon checking the cng system the gas injectors warent working properly. they werent repairable so i was told to replace the injector rail. upon confirmating the price they were Rs 20,000, i was shocked. i then took this matter to warranty and after a long discussion they agreed to replace it under warranty. after a week it got replaced and i was told not to pour water straight on the injectors upon wasing the engine.
