Something I keep a note for on my phone, because it sneaks up on you.
Our cylinders are not a "service it when the light comes on" item. Indian Standard rules say every CNG cylinder gets hydro tested every three years, and IOAGPL's explainer puts the going rate roughly between Rs 1,200 and Rs 3,000 depending on where you take it. They depressurise, clean, do an ultrasonic wall check and then issue the certificate. Worth reading once if you have never seen the actual steps: https://ioagpl.com/all-you-need-to-know-about-cng-cylinder-hydro-testing/
The other bit people miss is the CNG filter valve. V3Cars lists it as a yearly or 15,000 km item on the Punch, with the filter itself on a longer cycle. Mine goes in with the regular service so I am not making a second trip to the workshop.
If you bought your Tornado Blue in the first half of 2024, your clock is already ticking. Anyone in Chennai found a testing centre they actually trust?
