60 pages of problems?


Having very nearly bought a TL, I have stumbled upon the thread outlining the fun that can be had with air-filters, EGRs, and dreadful Nissan after-sales service. The thread alone is enough to put anyone off.

To put this into perspective, can anyone shed some light on the failure rate of these cars? Are we talking about a small percentage, or is this an epidemic? Should I be considering other options, or am I running scared based on the feedback of a couple of disgruntled owners?

Thanks in advance for any help that you can offer.

Re: 60 pages of problems?


Hello Chris,

It is not 60 pages of "problems" but rather 60 pages of discussion solving and finding a solution to a problem which all new Euro4 compliant diesels in Australia are having.

One of the solutions, specifically to stop the annoying blockage of the DPF, is just adapting the way you drive the diesel to suit our different conditions and urban usage compared to Europe where the Renault M9R was developed.

The other solution, to erradicate oil deposition on the air filter and intake/intercooler piping are the fitting of a secondary oil separator filter, exactly the same as the part which is causing the problem internally in the diesel engine, to enhance its function and provide further protection to the engine.

There is also one member who reports they have not had either of these things occur in his diesel and there is also the extended warranty option to have Nissan do any fixes required for the 5 years.

Re:


Chris, I understand how your feeling right now about purchasing a diesel, that is why I directed you to this thread.
Kevin is right, it is a thread about trying to understand the engine.

Don't forget that every modern diesel engine has an EGR which people do block as a mod to stop the carbon building up.
Other manufacturers such as Subaru, Renault and Hyundai also have the above issues you mentioned.

Re: 60 pages of problems?


Chris as Tony said all modern diesels which comply with Euro emissions standards have issues with EGRs etc. Everything from Mondeos to X-Trails. You just need to know that some extra maintenance will be required with these motors. Namely EGR cleaning and a possible crankcase filter (oil/air seperator - Provent 200). Your mechanic could do the EGR cleaning every service if you ask them. I'm sure after the first go at it, they would find it very simple and not charge much. As for the provent mod it is also very simple and you can follow what others have done on here.

The other issue is the Diesel Particulate Filter (DPF) in the exhaust system (another Euro emissions thing). This appears to be faulty on a vehicle by vehicle basis rather than a model wide problem.

Other than this the diesel is really good. Better for towing than the petrol and in my opinion better off-road.

Whenever you buy diesel over petrol you need to know that maintenance costs will be higher. The Euro emissions thing has just meant that the gap is now a little wider than it was before.

Re:


I do a lot of long distance driving between Canberra and Sydney and haven't had any oil on filter issues or dpf issues. Like others have said, it's to do with the new euro standards. Other diesels are having serious problems
Cx-5 and the oil overfilling the sump. Mazda fixed it by telling everyone to check their oil level every 2000kms
Subaru diesels in foresters constant flow of replacement for $1k
Poor build quality of captiva

Re: Re:


I've had my TL for 16 months now and I, like some others, have experienced the EGR and DPF issues.
However I'm through the other side of them and we still LOVE the car.
As others have said, much of the problem with the Euro 4 diesels in Australia is centred on two things - our driving habits in Australia (which are not conducive to long life of the DPF) and more importantly, the poor quality of the diesel in Australia when compared to Europe...in particular, the sulphur levels in Australian diesel. It is the sulphur in diesel that is the main source of soot formation and therefore the flow-on effects on the EGR valve and the DPF.
I have had nearly 30,000km of really fun motoring out of the TL and whilst I acknowledge that the EGR and DPF issues were not fun, I was very happy with the great service I got from my Nissan dealer in resolving the issue under warranty and the recent ECU system upgrade is supposed to address the EGR/DPF issues.
As others have also said, the EGR/DPF issue is by no means confined only to the M9R engine, and I think that it's an important point to note.
In the end, I'm back to 7.6L/100km around Canberra and we're loving the car. It's fabulous off the road and on the highway.
Finally, remember that nearly every brand of car has specific technical issues. These are nothing new and as long as you are aware of them then you can take measures to reduce the risk of it happening to you.
Good luck.

Mark

Re:


The question you really need to ask yourself is "Do you really need a diesel?"

* Do you do long distance dirving on daily basis?
* Do you plan on towing something heavy (i.e. boat, camper...etc) with your car?
* Can you afford the ongoing added costs of servicing the diesel?

If you have answered yes to all of the above, the diesel is the right choice for you, but if you are only choosing the diesel xtrail because of its manual transmission, I suggest you re-think your choice and look at other options.

Re: 60 pages of problems?


Thanks for the replys people - it gave me something to consider.

Having driven the Ti, and based on the feedback that you've given me, I think the diesel may be an unnecessary complication. I was expecting to dislike the CVT, but actually found it quite a pleasant thing to drive. Certainly no worse than a normal auto, anyway.

First priority is to unload the Foulcon, and then it's ST-L and Ti hunting. Keep your fingers crossed for me!

Re: 60 pages of problems?


I agree with all of the above too - however one significant reason I bought the diesel was the 6spd manual transmission - it complements the M9R very well. I don't drop it into top unless I am doing a constant 110 or higher.

Having recently purchased an OBD2 scanner I also think I will have slightly more confidence if a MIL light comes on unexpectedly in the middle of nowhere, knowing if the fault is 'return to base' immediately or not.

I am still a fan of the diesel Xtrail.
