I have recently acquired a 2005 Nissan X Trail with the 2.2 diesel engine. My first trip with the snail on the back was a relativley short one of 65 miles. Mostly dual carriageway. All went well until around 40 miles when I experienced a loss of power. I change to a lower gear for a short while and all was fine for around 5 mile when it did it again. The return journey showed the same syptoms but only once. The temp gauge showed normal, no warning lights came on and when driving around normally without the snail it drives beautifully. Has anyone experienced this, if so what caused it?
Many thanks Izzeybear.

Hello Izzy,
I'm sorry to be so nagative on this point, but this type of question without far more detail is almost impossible to answer on a forum.
There are several different things that can cause the symptoms you describe. It could be one of the specific items already suggested but equally it could be several others. Unless you have specialised knowledge and access to test equipement its unlikey you could just look at the componenets and tell if they are faulty or not.
So the most reliable route to solving your problem will be to have the engine diagnostics checked by a garage, (any worth their salt will have ECU readers decoders for fault codes)

It sounds like you have a problem with teh Diesel Particle Filter (DPF). Normal a run of about 10 miles on the motorway keeping the revs high resolves the issue. The problem normally occurs if the car is used around town at low revs. A deposit builds up on the filter as the temperature is never raised enough to burn off the residue. Try the run before spending money at a dealer!

I don't think it would have a DPF as a 2005 model and normally DPF issues give rise to a dashboard warning message. Take Prof johns advise and take it to a garage for a diagnostic check.

Can I suggest that OP joins the Nissan Xtrail forum for better advcie before they spend money on what could be an unnecessary repair. Here is the link. http://www.x-trail-uk.co.uk/viewtopic.php?f=43&t=1872

Well that may help but OPs description of the problem is hardly comprehensive. Unless the car is self healing (rare) its going to need some sort of repair and a good diagnostic check by someone that knows the model should actually save uneccessary repairs and nugatory expense.

As there is no apparent warning light associated with the loss of power, there is no way anyone on any forum can provide a copper bottomed guaranteed corect answer to the OP's question. We simply do not have enough information to draw a reasoned conclusion. That being so, if an engine is apparently faltering, then it is unwise to run it until it has been inspected and where possible tested to acertain what the fault is. There is the possibility that runing the engine with an un identified fault may cause some very expensive damage. It is therefore a logical and prudent exercise to get the vehicle chcked by a professional.

My friend has 2003 X-Trail ,had it from new mainly for towing.He has had it several times over the years and each time puts RED-EX diesel injector cleaner in his tank and it has always cured it.

It certainly won't do any harm to run redex through. I would guess that like many of us, yuo'll of been running supermarkey fuel.

I have invested in an OBD2 reader lead and CD disc for my laptop to help me diagnose any faults on my Jag diesel. However if you're not a petrol head like me, you can get a diagnostic assessment done by any competent garage. But you will have to try to find one you trust as they can be prone to trying to pull the wool over your eyes. By joining the X trail forum you might find a locally recommended specialist who can help.

You can have an OBD data collector plugged into the diagnostic socket on your car so that it can record the "live time" fault when it happens, this gadget is handy for intermitant faults. I had a situation on my Jag where it missed a beat randomly. It turned out to be a dollop of gunge getting onto the cam position sensor which stalled the engine for a couple of revelutions.

I run a 2004 XTrail 2.2dci ,it could be slipping into what they call a get you home mode 50mph max,it happens when an engine sensore picks up a fault,either temporary or permanent.I have had it happen on 2 ocasions with mine though not while towing although both times the engine management light came on as well.First one was a drop in air pressure on one of the sensors cause it had sucked a fly into the intake .Next time was an injection fault caused by a fractured wire once again leading to a fuel sensor,i was on the Cambridge bit of the A14 not able to do more than 50mph HGVS front back and side not good,took the RAC man 20 mins to find and cure excellent service.Sometimes you wonder to save a few imissions and a little fuel if all of this technology is realy needed,it can lead to many problems.Hope you get your problem sorted.

Hi isseybear
Hope you have sorted your problem out by now, but I had the same happen to me on my 2005 xrail & sorry to say it was the Turbo blown & it was like yours no warning or lights just suddenly lost power, had mine sorted only for it to happen again 8mths later while towing our van,
I was told there had been a Nissan recall, but as second owner did not hear of it till to late, So I hope yours is ok.

Hi new to this but after buying my xtrail in February this year it's been a nightmare! Power loss with no fault codes or warning lights, when reaching a hill felt like you were towing a train behind. I replaced the suction control valves (£200) no joy, various engine, injector and turbo cleaners but still no joy! Car pulled on flat till 3500 revs then held back. Tried to trade car in but best offer I had was £1500 and had limited funds to add so that was a no go. Spent hours searching the net but still could not find a fix. Anyway after getting so pissed off I adopted the attitude if "what the hell" and began attacking the car with various spanners, and found a fault so simple I could kick myself (Iv spent around £500) the mass air flow sensor was dirty so removed and cleaned with ecu cleaner, replaced and...... No better I then removed the housing the the maf sensor fits in, the whole pipe and top of the air filter box. Inside there is a mesh that prevents debris before it gets to the air filter. This was blocked by soot and flys etc so a wash of the whole thing with soapy water (left to dry thoroughly) then replaced. The car now pulls fantastic and is the acceleration is smooth through to 7000 revs. I hope this helps someone

...........it is a shame you did not find my third post in this topic of over two years ago!!!

As far as Nissan are concerned, changing the Mas Air Sensor involves the Sensor and it's housing and it's protective mesh!

except he didn't change it did he, he merely cleaned it and removed all the debris that had build up....! like the prof said 2 years ago, loss of power can be caused by 50 different things,just changing things and hoping is a costly way to do stuff,and no guarantee to a fix.

....nowhere in my posts did I advise changing the Mass Air Sensor.
I advised to check it.

My reference to the Nissan part was to demonstrate that Nissan do not supply just the MAS, but include it's housing, the relavent seals and the protective grid.
To me this undelines the importance of cleanliness around the sensor and the integrity of the air intake.........it was this fact I was trying to get across by mentioning it.

Indeed you did mention to check the maf which is the sensor, you mentioned nothing about the housing although most reputable deals have the maf sensor sold in leu in the housing.. And anyway how does one check an maf? Without knowing A. It's airflow rate gram/sec or min. Or knowing it's volt readings.?

disconnect the mass air flow sensor and see if it makes a difference on performance

.............exactly Seth and that is what I did to check it on my Nissan at 65000 miles.
Disconnecting it electrically made no difference to the engines previous loss of power so at that mileage I replaced it with a new sensor.
Result engine back on song :)

And so i now bring you back to the OP problem he suffered a loss in power, occasionally whilst driving.and not a lack of power all the time! simply don't see how your test would have been any help to him or anyone with a similar problem.the simple test you mention only works on a truly out of phase Maf. the maf could be faulty and still pass that test..i am not being pedantic ,for once and it is a shame the OP did not come back and post if he got the vehicle fixed .simple changing the MAF in most cases is an expensive waste of money it can be cleaned up isopropyl ,besides in many cases merely changing the MAF because one has herd through the great vine can be an expensive short term fix.. if you have 2 sensors not at there best and one is the maf which could still perform adequately for a long time to come changing the MAF improves things for sure but had you bothered to get the car checked out properly you might have found the culprit to be a cheaper option....most of the internet traffic dates back to a decade ago and cars build pre 2003 bosch denso and the likes improved their MAF after that date making them far more reliable.although reading the internet one wouldn't of thought so,its like they are always going wrong!

I've never had a Maf problem on any car.
I do have a copy somewhere with common faults printed in diesel car years ago, if the OP does return then I'll look for it.

If not I won't.
