Major Problem- some advice appreciated

[ova50]

If I were you I would be fitting that Scangauge ASAP. They are not that hard to work out. Fitting takes 2 minutes.

Put the scan guage in this morning, I did not bother setting the fuel info for mileage/distance etc.
Is it ok to do this at a later stage, or should it be done now.??
Scrolling through the guage I have found the usual things like rpm, voltage etc. Found one that reads, no codes found (i assume this is an important one) plus heaps of others.

Any advice as to what I should be looking for as far as the readings etc on the guage??
Any info is appreciated (except if is stuffed, wont appreciate that,lol) Should mention my Patrol is an auto.

I was also having a look around the engine this morning (not that I have a clue what I am looking for).

However I happened to wiggle this hose (attachment) and it quite loose, could have removed it without undoing the clamp. I figured this should be tight so done it up, now secure. ( clearly Nissan saying they have checked all hoses etc is pure crap and will will be nailing them when I see them)

I went for a short run and the smoke is still there but I dont think it is quite as bad. (unless its my brain playing tricks on my eyes).

I have spent most of the day documenting the conversations, dates etc, that I have had with the dealer.
Still all up in the air at the moment. (damm, Im starting to miss my old 4b)

Don;t give up now mate, you've done the hard yards ...just wait and reap the benefits. Nissan will be responsible for any work needed and they WILL fix it ...they have to.
It might even pay to see the pollution people and get them to measure the output from exhaust......

Make sure they cover all your expenses associated with this issue..... You've been mucked around enough.

GOOD LUCK!!!

Don't worry about fuel stuff yet. You can set that up any time.

Just a couple of quick things to set up are the units it displays, ie miles v klm etc, the size of the engine and type of fuel (DIESELa). Follow the instructions in the booklet and set it up for klm and ltr, temp I set to Celsius, for Manifold Pressure set it to BST not MAP, pressure units to PSI.

Select what readouts you want showing. For now I'd go with Boost and Temp and any other 2 you like.

Ooops clicked the wrong button!

Factory boost readings on my car were a steady 16-16.5 when I planted my foot with a momentary spike to around 18, the Scangauge might not pick up the spike as it drops in less than a second, around town boost rarely gets to more than 15 and with a light touch on the throttle to maintain 60-70kph it sits around the 10-12 mark or less. So if your readings are similar to those boost, is good. Temp is high 80s to a max of 91c so far for normal driving, even on 35+ days.

I don't know if you have EGT gauge but my temps are around 250-300c normal driving around, 400 or so pushing it up hills, I haven't seen it get to 500 yet.

Good luck mate, hope this helps.

Sounds like Mr Nissan up to their old tricks,

I wish you well in getting the problem sorted asap Ova50, & the following comment will be of absolutely no help to you, but nevertheless I can't help myself from making it.
The stories that abound about Nissan doing what they can to avoid their warranty responsibilities seem nothing less than shonky to me, I would never buy a new Nissan, despite being the owner of two Nissan vehicles. Their spares backup for my '89 model bus is also pathetic. (Pay first, see if it's available ex Japan, wait a couple of months if it is & pay the price based on the parts equivalent weight in gold! I really wonder how they stay in business with such a crap reputation, even though the vehicles they build are on the whole as good as any other & can only come to the conclusion that it is their lower purchase price (than Toyota) that keeps them in the market. It's the lack of 'How can we help' attitude that really pisses me off. Ova50's story is nothing new unfortunately.

Just wondering if you have a chip in your 4x4.??????????
Change those child clamps for constant pressure clamps
a bit more pricey but well worth it around $8-$11 depending on size

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.

I agree with the others who have stated about documenting everything.

You say that you were told that it had carbon build up. What has been done about that?

[mudski]

Ova. You say you found a lose clamp. Take the cover off the engine and check them ALL yourself. Check for any splits in the hoses too.
Without re-reading the thread. Has the intercooler been checked for leaks?

[ova50]

To Lonicus: Thanks for info on the scan guage. Is your vehicle an auto??. I assume that some readings would vary depending on whether it is an auto or manual.

EGT gauge, dont have one.

Threedogs: Apparently no chip has been fitted, and agree with you about those stupid clips. I am planing to replace as many as I can.

Ben-e-boy: With the alledged carbon build up. The dealer says it needs to be taken for a long run and by doing this it should blow out & clear the built up carbon, claims the carbon build up would have happened because of the split egr pipe. I will ad, that statement does not sit well with me. The egr was supposedly removed and clean. Surely there is only so many places where you may get carbon build up. (maybe when Im at the dealer again, maybe I will be told its in the boot or glove box )

Mudski Im am begining to think that they havent checked as much as they claim to. Hell, I know stuff all about diesels & turbos, yet I found a loose hose and clamp and in plain view. This alone puts a big question mark over the dealers quality of workmanship, service and honesty.

They may or may not have checked the intercooler for leaks, they have not mentioned the intercooler.
I will take off the top cowling on the weekend and check as many hoses & clamps as I can.

Can I check the intercooler for leaks myself and what is involved, is there any particular area that is a common place where a leak might be or happen.??

I have to use the vehicle tomorrow morning and will be travelling about 60ks, hopefully I will be able to check the numbers on the scan guage and compare with what Lonicus has supplied. Then check as many hoses I can.

If I think the smoke has reduced, (and since tightening the clamp) I am planning on taking it for a run up the coast on Sunday.

(apologies for any spelling errors guys, been a long day.) Damm that took a long time to type.

[Lonicus]

Yes mate, mine is an auto so readings should be pretty much the same.

Yes mate, mine is an auto so readings should be pretty much the same.

Thanks, that will give me a good starting point. I forgot to mention that when I plugged the guage in and was scrolling through some of the things may have been detected by the guage or could these have been pre set. ones I noticed was fuel already showed diesel, Engine already showed 3.0litre. and remember seeing a bst displayed and not map.
