I have a 2015 Forester Diesel and the idle is rough, also the turbo seems to only pull well intermittently. I want to clean the EGR valve out as I know this can cause these issues.
 
	My questions are:
 
	Where the hell is it!
 
	And if I have to remove the top mounted intercooler, is it ok to just remove it or do I need to take anything into consideration first? (This is my first Subaru/Turbo charged car.
 
	Also I was going to change the oil and wondered what oil you Subaru Diesel Gurus would recommend its on 75K miles.
 
	Thanks in advance ^_^
