No tire pressure warning even at 15psi

My F10 doesn't alert me even when one of the tire's pressure goes down to 15 psi.

My car (in India) has the ABS based simple flat tire monitor. Runs on 225/50 R17 RFTs set at 30 psi. One of the tires is having a slow leak and the TPMS did not alert at 15psi. I filled up all tires to 30 psi, reset the TMPS through iDrive. After few days the pressure is down to 20psi but still no TPMS alert.

Dealer says this is not uncommon due to a stiff side wall of the RFTs and he says for some cars TPMS is alerting only when the tire is flat - but he is willing to diagnose the problem if I bring the car over to the workshop. In my previous VW cars, pressure loss warning was pretty reliable and was quite useful.

Is there anything I can do to get the right diagnosis? It is a new car with 5000 km on odo, ABS works great

Thanks.
