u mean the grill in between fog lights?i just noticed that area,i never shampooed that area :o n that area isnt visible either,its just that i took pic in a way that area became visible otherwise i dont think its visible,will wash it next time 
no problem 
whenever i get cng adjusted from there,it seems like pick has gone down instead of going up 
they always do the setting on petrol in last n i forget to convert it to cng n keep testing it on petrol lol,happened twice
