Re: Recall Catalytic Converter & O2 Sensor Breakage
Hi Jalal,this filter is a mystery to me as my local dealer keeps telling me it is for life,and can not find a referance to it being changed in his service manual.I thought it should be changed and i will be happy to have this done if nothing else but to remove it from the problem i have with my engine stopping. Do you know the cost of the filter and whether it is a big job or not?I sort of believe that the cracked manifold around the O2 sensor might be part of my engine cutting out which on the last time caused me to loose my power steering going around a tight corner and the lady who was behind me nearly hitting me in the rear end,and abusing me no end.The cutting out problem (happened twice) i am hoping will go away now i have had the engine checked on the dealer computer and nothing was found but the cracked manifold which is now repaired.I think you are right the filter does need changing as i feel nothing is for ever and a blocked or even partly blocked fuel filter can cause all sorts of troubles.cheers

Re: Recall Catalytic Converter & O2 Sensor Breakage
Copied over from the Warranty Repairs thread:
10 Nov 08
Warranty work for the cat converter all done, thankfully, last Thursday.
Probably drove about 35km in total, then on my way to work this morning, the orange light was on. Went to the dealer at lunchtime and left it there (cab back to work $18.60, ouch).
At least they were able to look at it today - apparently the 02 sensor wire was not secure, they refitted it. Person at the desk said it could have been bumped when it was worked on!
Comments about the dealer I will note in the appropriate section, but not tonight. Time for another letter to Nissan I think.
07 Dec 08
It's a couple weeks now since the work was done, and the poor old thing just doesn't have it any more. When accelerating she has a really dragging feeling generally and often misses.
Spoke to local dealer Kerry Auto (who did the work) and they reckon it probably needs a tuneup or got dirty fuel filter.
I've booked it in for a diagnosis on Tuesday, I don't imagine they'll come up with anything helpful. The only reason I'm going back there is because I reckon it relates to the cat converter. For some strange reason I thought that when they put the new cat converter in that they would make the car run properly as well.
The service manager said that I should expect the dragging feeling since the cat converter was creating a barrier where there'd been none for probably some time. I thought that she would be running freely like she'd always done.
He was just so helpful, not. And sat there fidgeting with his hands and his pen and looked very much like he wished I'd go away and leave him alone.

Then don't go away.
Like Jalal, I recon you need to push him for a compression test on all cylinders.
If any of them are anywhere near "just OK" or especially below spec, then atleast a new short block should be supplied under warranty.

Re: Recall Catalytic Converter & O2 Sensor Breakage
Yes I will push on the compression test.
When I told Kerry's that I could still hear occasional rattles at start up, they said there could still be bits of the converter floating around in the other mufflers, but that it was okay.
I rang RACQ Technical Section today and the consultant there said that all rattles should have been fixed, and also that the loss of power could be due to a larger piece being stuck somewhere. He did also say that it could be dirty fuel.
Anyway, it goes in tomorrow, and unfortunately I will have to outlay some cash, or it won't get done - I did manage a deal on it though. When their customer service person rang to ask if I was satisfied with my recent work I told her NO and why, and about the stuff ups they made a couple years back as well, so she offered me my next service for half price. Since I'm not ever going to have a service with them again I offered to pay $50 for the diagnosis instead of the $200 or so they quoted. Possibly I'm still being ripped off, but what can you do??? 8(
I just wish it was finished, but at least I'm thankful that I don't have the problems so far that some other people have at the moment.
cheers

Re: Recall Catalytic Converter & O2 Sensor Breakage
Had the exxy diagnosed today. Talked to Kerry's service manager beforehand and one of the other attendants.
Told him I'd spoken to RACQ and what they'd suggested. Asked for the compression test. He said it wasn't normal and commented it was a $50 diagnosis taking half an hour!!! I corrected him on the matter and reminded him of just how our conversation had progressed last week and he conceded that it was $200 worth of diagnosis.
When I came to collect the vehicle after work, the service manager personally attended to me and was very very very very nice to me, and waived the cost. (Might have been because Nissan Customer Service might have mentioned I'd called them yesterday for advice and also told them of the abyssmal service and lack of professional attitude.)
They did find a chunk of cat in the last muffler and removed it, and also found a heat shield had come loose and fixed that. They had done all the computer diagnostics and everything came up fine. Road tested it and found it to be performing just fine, of course.
I have an inkling it may have been the heat shield all along that I could hear rattling, and that it was just a lucky fluke they discovered there was a problem with the cat converter.
As for the performance, maybe I'll just have to give it some exercise and it will pick up again - bit like a human. It's only been doing 2km jaunts to and from work most of the time (I really should have been walking or riding the pushy) with an occasional 15km burst. So it needs a really decent run with a bit of variety.
Hopefully that's it for all warranty work, since this has been the 4th warranty issue on this vehicle.
Now I just gotta find the right place to do my servicing from here on.
Thanks for all your advice everyone.
Julie

Re: Recall Catalytic Converter & O2 Sensor Breakage
Did they give you any figures for the compression test on the cylinders Julie ?

Re: Recall Catalytic Converter & O2 Sensor Breakage
My advice to all xtrail'ers who plan to keep their vehicles past the warranty period:
- Almost all ceramic cat converters in any car will break up over time. As the engine ages it gets less efficient, putting more strain on the cat.
- The Xtrail header design is flawed. The O2 sensor recall which slightly detuned the engine, sounds to me like a stop gap measure to get them past warranty period.
- Once the cat breaks in the header, there is a chance some particles will be sucked back into the cylinders causing engine damage.
- Its very difficult to see if the cat is broken as its enchased in the header. Only a destructive examination will prove it either way. And thats expensive.
- Nissan have officially told me they will not repair a broken cat outside of warranty period.
I'm no mechanic, but I would suggest that xtrailers seriously consider replacing the header and cat with an aftermarket one. All aftermarket ones put the cat much further back down the exhaust (away from the engine), and some have stainless steel cat's which will never break up.
You have some options here:
- Jalal's Hi-tech option. (Bathurst & Sydney) This is the premier solution which replaces your whole exhaust, gives extra performance, and looks hot! About $2800 installed
- Di Fillipo (Melbourne) have a stainless steel header + ceramic cat at about $1100 installed.
- Hurricane Headers (Liverpool, Sydney) have a mild-steel setup at under $1000 installed.
All have pro's and con's and you need to consider the age of your xtrail, and budget. All will ship the parts to whatever state you are in for around $100.
Your best bet is to talk to your local performance exhaust shop, and they can give you more information on these options and talk you through which is the best.
If you are planning on keeping your xtrail long term, then I would definetly change the header (including cat) before it does any damage. You can ask your local mechanic for a compression test (usually less than $200) before hand to make sure the engine is in top condition before spending the extra money.
Information on the cat issue is here:
http://myspecv.com/f/t4739-qr25de-precat-and-butterfly-screw-faq.html
Rough guide to costs:
A new Nissan header ~ $1600
Rebuilt Xtrail engine > $4000
Strip an engine. (to diagnose problem) $1100.
2002 (first model) Xtrail red-book value ~ $10,000

Re: Recall Catalytic Converter & O2 Sensor Breakage
Thanks Geoff,
All of these options have already been listed as part of the "aftermarket exhaust upgrades thread" and the link you have provided to the SpecV is good, but not all of it applies to our xtrail, an example of which is that we don't get the check engine light after changing the extractors and we don't need to extend or buy a gadget to extend the O2 sensor wires to avoid this check engine light problem the SpecV guys are getting.
You're right about choosing the best option to suit your budget and the age of the car and you're also right in saying that some options provide a fix, while others provide a fix and increase in power and hot looks, so every situation will be quite different. I have always maintained the fact that changing the factory ceramic cat. converter is a MUST for anyone wishing to keep their exy for a long time. It is the safest bet and with Hi-Tech offerring 10 years warranty, it is the most logical one too!
