I bought my Dzire ZDI (AGS) this July. I guess I know what sound is that, it's not a rattle. I think it comes from the door rubber sealing, just for a test apply some Vaseline to all those rubber lines(all 4 doors) and check if the sound comes. I am demanding replacing these in my 3rd service. Let's see if I win.
Thanks for replying, I did not get exactly which part or where you are asking me to apply vaseline, could you please take some pics and mark the area, that would be appreciated.
As on this Saturday(12th Nov) I have to visit MASS, I will try this quick method before that and check, so please if could post some pics it would be helpful.
