Hello guys,
	
	I just bought Qashqai j10, 2012 with 1.5cdi 110hp engine and and i have two questions:
 
	 
 
	1) I just found out that the intelligent key button from the tailgate is missing. There is an empty hole on the boot and i wonder if intelligent key can be installed? If not, what should i do with the hole?
 
	2) What engine brand should i use? I know it's 5w30, but does it matter which brand?
