Apologies for the length of this.
Recently I started a thread about the Extended Nissan Warranty. In the thread I mentioned that my Patrol was at the dealer and had a couple of problems. It had lost power and was blowing excessive black smoke when the vehicle had warmed up. The Dealer replaced the EGR pipe as it was split and cleaned the egr. I was told by them the take it for a good run because it needs to reset itself.
Two days later I booked the vehicle back in, as it seemed to be getting worse not better. Got a call from them to say to they replaced the MAF sensor as some codes showed it was faulty, and its much better. Was again told to take it for a long run up the F3 (syd-newcastle) as it had carbon build up due to the spilt egr etc.
Half hour later I was back at the dealership, an told them I did not feel comfortable driving this up the freeway because it is billowing black smoke and is heaps worse and did not want to risk it. Eventually they said to come back in the morning. Picked it up today and was assured it was carbon built up and to take it for a run. I told them I will call them tomorrow when I get back from the run. My wife followed me home and the smoke is worse, my wifes words were "the smoke looks greasy if the sun hits it, and once you could faintly see the colours of the light spectrum.
So Im meant to take this for a long run (maybe a 150k round trip) (oh, the dealer has put this "take for long run" on the invoice)
Gets better, we have dinner tonight with guests, one of which works at the dealership & happened to work on my vehicle (dead set, guys). He says its carbon, and the CDRs do smoke, yer, but not like mine does, I say. Then tells me that Nissan wont do any more as they deemed it all ok, and that if they done, for example a compression test and found something major, it would depend on the vehicles service history whether it would be warranted. Whether this statement was from Nissan or the dealer, I dont know. ( I bought this second hand in October last year).
My vehicle is a 2010 3.0litre DX, has 95000ks and close to warranty expire. My wife and I have been sitting here discussing all the what ifs about this whole thing.
I anit no diesel guru but I dam sure this is over fuelling, dealer says no, and claims its carbon blowing out, and now its mentioned Nissan or the dealership wont do any more.
I should ad that I had this at another dealer ship in another state recently, had a bad fuel smell, the fuel rail or pipes were replaced, whether it is pure coincidence but the vehicle appeared to feel gutless on the odd occassion. A couple of times on the way home we did notice some smoke but was up hill and the van in tow.
AHhhhhhhhhhhhhhhhhh!
If anyone has some advice with our dilemma (apart from going balistic) We both would appreciate it.
