Hi Guys, Had you find anything or answer from the dealer. Or getting any information from someone else. I have that problem quite some time and some one said said not to worry. But, inspection time it will fail. Your finding and fixing information will be appreciated.

 

The EGR valve is pretty easy to replace and inexpensive ($40-$50). Its a valve with 2 small hoses and a hornace connected to it, its held on with a 10mm bolt and its located on top of the engine bay so it wont be a problem to get to. Order it from JerryRome nissan there prices are great.
