Hi, I have a strange problem. I noticed that both dashboard green indicator arrows come on whilst driving for about 10 seconds. They don't flash, just stay on. No change in the vehicle condition at all, ie no loss of power or anything. This has happened twice in about three weeks, I just haven't got a clue what it could be? Help or advice appreciated.

I have a 2.5d outlaw automatic with 69,000miles on it. The last month it was been stalling on a cold start, to begin with it would just be the once, but it has since become un-drivable. I've noticed that the rev counter continues to show revs for a second or two once the engine has stalled, the egr is also blanked off.

hello im driving a nissan navara 2007, it just started low power when im driving, but when i switch it off it gets normally for some few minutes driving then low power again, i have serviced it last month july 2014. please help
I am having the same issue and the garage guys said that EGP, CGI and low pressure, I can't get 60 or 70 KM/H. They are suggesting I should change it or do reboring. I am totally stuck and frustrated because I imported it from UK just 4 months ago. Seif Kombo Pandu from Tanzania

Hi, I recently brought a second hand nissan D40 from my local dealer, they said they rebuilt the timing chain and motor, but now if I go a little bit over 4000rpm it's like my turbo just shuts itself off and I have to turn the ute off then back on and works fine again til I go over 4000rpm, is it a sensor stuffing up or just a safety thing for the turbo?

I have a 2006 D22 duel cab STR and the front speakers only work intermittently, usually in hot weather. I thought it may have been the radio, so I swapped it for another, however this has the same problems. So I imagine it may be a faulty connection or dry solder joint. Any ideas where to look?

It all started with the alternator not charging. Found the problem was with the pulley clutch system. Had it welded to the shaft to isolate the slipping clutch. With this arrangement the alternator output is 14.2v. But the problem now is the car looses power and smokes. A lot of sooth accumulates at the exhaust pipe. What could be the cause?

I recently took my Nissan Navara D40 for a major service where they changed the gearbox oil. When I left the garage there was a bad gearbox oil smell in the cabin, and thought it will go away, but the problem does become any better and the smell continues. This morning when I drove it, it was difficult to engage the lower gears as they were so stiff, and the bad gear box smell continues to suffocate me in the car. Please help me, I am now reluctant to use the car...

Hi, my Navara is 2 years old and we are starting to have problems with our radio and ECM. The radio has a different name for the station it is on and the Bluetooth plays up. The radio has just been replaced and is still starting to do the same thing. The car wouldn't start a few weeks ago and I had a Nissan technician look at it. He jump started the car as we thought the battery might have run flat but once the car was started the engine light came on and I lost all electronic gauges, all went blank and then restarted themselves. My Nissan also is lagging a bit when first put into reverse. The technician told us to get it towed to Nissan and they recharged the battery, the technician said the charge was just under 12V when he got there but assumed it was just from us trying to start the car a few times. They replaced the radio unit also cleaned some of the contacts around the ECM. Within the week my Nissan is back at the dealer for the second time to find the same problems. What could be causing this, could we have a faulty ECM?
K, Just for giggles have the battery removed from the vehicle and load tested. If there is any doubt about the battery, REPLACE THE BATTERY. they only have a 2 to 3 year warranty for a very good reason...... (Keep the old one if there is still a possibility of using it to jump start another vehicle at home, especially if you have your own battery charger...otherwise get rid of it.) While you are doing this and have the battery terminal clamps in your hands, clean them to shining brightness, and then clamp those shiny clean clamps tightly to the new battery's terminals. Your whole car relies on a good battery. Showing 12v at any time unless actually cranking the starter motor means that it is not a good battery..it should be at least 12.4 volts even after cranking for some time. Low voltage = problems. Jump starting a computerised vehicle is fraught with danger. Don't be penny wise and pound foolish. Then, when you have a good battery in the system, check the charging circuit, check any trouble codes, clear them and drive for a while. recheck for any trouble codes.....you should be good to go....

Hello. I own a Nissan Navara 2006. A few days ago, I was going home when suddenly the driver's left side airbag exploded (the seat airbag too). Luckily the road was safe, i was going in a straight line and there were no cars near me. I did not hit anything before or after the airbag went off. Just to be clear, the airbag i am talking about is the one that comes down form the roof and covers the windows. Did this happen to anyone around here? I believe this is not the first time something like this happened, because i red about a recall due to airbag defects, but only in US, uk.. I am from Portugal. Will nissan take care of my problem? Should i be worried about other airbags? Thank you, Pedro Farrancha
Pedro, only your Nissan dealer can answer these questions. BEFORE you go to him, take lots of photos of the exploded bag...and see if a local newspaper reporter might be interested in a good story. Then go to the Nissan dealer, take the reporter along as a "friend" of yours and start asking hard questions. Depending on whether they say "yes" to replacing at Nissan's expense, or not, when you get to the real Manager of the place, and if the manager still refuses to replace at their cost, reveal that your friend is a newspaper reporter and the story will be in the paper... He may well say "yes" then. If so, get it in writing and be careful that nothing else gets done to your car while they are replacing the airbag. The reporter gets a good story either way.

Hi, today I have no hot air from my heater. I noticed water on the passenger side footwell and eventually it started runing hot so I checked the water level in the rad and it was very low. I`ve had no problems before. Can you help?
Mark, you may have a leaky heater core. or a leaking hose from the engine to the heater core. As a keep-you- going- without -a -heater, find the two hoses that lead from the engine, (usually near the thermostat housing), to the heater. Remove them from the engine, and buy another small length of the same hose to connect and loop the water from the output spigot to the input spigot. Then refill the radiator with coolant and run for a few minutes with the radiator cap off and watch for bubbles of trapped air, refilling the coolant to the correct level until no more bubbles appear for a couple of minutes. Put the radiator cap back on tight, and refill to the Min level the overflow reservoir. You should be good to go, and you have all summer to check out the cost of either changing the heater hoses or the heater matrix itself...Google it and see youtube vids on this.

Hello, my battery went flat on my D22 double cab 2.5 di, tried to jump start, turned over but would not start. I noticed that the immobiliser light was on , disconnected battery and fitted and new battery, but when tried to start it only turned over. Gone into Nissan Dealership in Huddersfield but so far after 3 days they have found nothing. The technician who is working on my truck is convinced its the ECU programming software which is too new. Any one any ideas or had this before. The hourly rate at the dealers is making me feel sick so I need it sorting asap. cheers, Simon
Simon, your problems started with a dud battery. The immobilisation system probably thought you were trying to steal the vehicle when you jump started it. The immobilisation system did it's job..it stopped the vehicle from starting (and being stolen) So, when you put the new battery in, did you reset the immobilisation system? There is a set procedure for this which should be in your manual. The mechanic certainly should have done this as a first action. John Smith from New Zealand

My nissan navara yd25 from thailand i did a complete service recently including injectors and a scan the problem is when i am going up a hill the engine cuts off, i tumble about 3 times before it restarts,also the gas gauge does not read properly, sometimes the tanks is full, yet the gauge does not show it and the gas light comes on, also i noticed when overtaking there is a loss off power, the main problem is the cutting off. i rechanged the fuel filter but same problems is repeating, this is the first time i am having this problems since i bought the vehicle please help chan trinidad
Chan, the first thing that comes to mind is that the lift pump that sucks fuel from the tank through the filter and then pushes it into the injection pump is failing. The loss of power from this means that not enough fuel is getting injected when going uphill or overtaking. Solution is to replace lift pump with another, or put 12 volt electric fuel pump in the fuel line to eliminate this fault in the future as well. Google lift pump failure and you will see it is world wide in many different engines. If you do not replace it the injection pump will wear out very quickly as the diesel fuel cools and lubricates it.... John Smith from New Zealand
Chan the fault with the fuel sender gauge can be a bad earth return from the tank to the body, or a bad sender unit. If you can put up with the light showing, or it will cost too much to fix...Use your trip meter and reset it to zero every time you fill up. Refill at say 500km; note how much fuel is used, and when you next fill up at the next 500km; check again. This means you have a very close watch on how much fuel the truck is using, and if it starts to use a lot of fuel..you will know straight away. John Smith from New Zealand

Hi all yesterday after work I tried to start my D40 diesel but wouldn't start had to pump the fuel up by hand then it started, got 2 ks from work and it stoped again, so I pumped the fuel up again and away I went, got home ok running very well, turned it off and tried starting it again all good. 2 hrs later I tried again and no fuel again. this morning I pumped it again and tried to start it with no luck, so I pumped the fuel up some more and went to start it and the motor wouldn't turn over. Its like the key is dead and no eng light, but when I turn the key on all I have is ABS, AIRBAG, DOOR, 4X4, HANDBRAKE, BATTERY, AND SEATBELT LIGTH on and no ENG light so cant get any codes. I have checked all the fuse, earths and fuel lines, 2 fuel lines were lose iv fix them, I tried cross the starter motor and it turns over but cant get it to do it with the key, there is power coming out of the key. Anyone got any idea what is going on pls. It is a Nissan navara 2007 diesel 6 sp iv only had it on the road for 2 weeks and was going well till now. its the 1st Nissan iv ever owned so don't know a lot about them. next weekend is a long weekend and want to go away so only have a week to fix it lol.
Alec, as a desperation measure, take the positive lead off the battery and ground it on the body work or engine metal for 2 minutes, this will force the ECU's to restart in learning mode. Have the security code for the entertainment system before you do this, you will need to input this as well. Now reconnect the positive lead, and pump up the primer until it is hard. now try starting the engine. If this does not work Google the many other fuel/line/filter/water/pump problems that people have had with this engine and see if any of their solutions can be made to work in your case. I suspect that the lift pump is now not working properly and i also hope that the main injection pump (which relies on the lift pump to always supply a good flow of fuel to cool and lubricate the injection pump) hasn't suffered any damage by running out of fuel.... Replace the lift pump with a 12v inline one..this should solve the lift pump problem. Once the injection pump gets fuel under pressure it should tell the ECU, which will then allow the starter motor to work by the turn of the key..... John Smith from New Zealand

Over the last month my aircon settings have stopped working. Two weeks ago when I turned my aircon onto the low setting (1) it stopped working! Now today it has stopped working on the next setting (2). Is this what happens when the gas in the aircon is getting low? Please help
Mick, Follow this logically; to activate the aircon pump clutch you need to have selected a fan speed which also supplies 12v to the clutch. The first speed of the fan crapped out, so the clutch got no power and could not engage. Then the second speed crapped out, so again, no power, no clutch, no air con. What happens when you select third speed..does the aircon work? So you may have a problem with the fan speed selector switch itself, or the resistor that steps down the voltage to provide the change in speeds. Is this fan speed selector a manual one (in which case there is a resistor inside the air vent housing)..just trace the wires from the fan switch to the fan motor and you will find the resistor in the line...it may be corroded and only require cleaning up to work. Use a multimeter to check that 12 volts is coming from each switch position to the resistor. If the fan switch itself does not work you will need to replace it. If the selection of fan speed is all electronic..you have to replace or repair the electronics... Re the gas in the aircon getting low..sort out the fan switch resistor situation first, then bite the bullet and get it checked by an aircon specialist who in most cases can do it while you wait... A precautionary check every 2 to 3 years on an older car makes good sense. John Smith from New Zealand

Hey John I need some advice. I`ve got a 2003 Nissan Navara 2.2 ZD30DDT. My truck broke down, the engine light was flashing so I towed the truck back home, checked the diesel filter, water on the bottom. I cleaned out the fuel system but it still will not start. I took the truck to get it tested (scannned, came back with faulty pump spill valve. Are there any other checks I can do and is my truck a common rail?
Steven, do some googling re spill valve and your engine type problems. http://www.navara.asia/archive/index.php/t-18466.html http://en.wikipedia.org/wiki/Nissan_ZD_engineThese engines are very sensitive to water and rubbish in the fuel. I fear some may have got past the filter and is now playing merry hell in your lift or injection pump, or both. The spill valve is a part of the injection pump. Start there; you really need an expert mechanic to help you with that problem.John Smith from New Zealand

Hi I had all the filters changed and now the aircon is not working and it`s making a sound like a cd changing?
Sharon, did a professional change the filters? Did the filter change include a cabin air filter that goes into the air ducting under the glove box? If so, could the professional have disturbed wiring trying to get to this filter? If so, go back to he professional and tell him to fix it... The other possibility is leaves etc being sucked into the fan and blocking it if the cabin air filter was not put back in place??? Unless it was at a Nissan dealer they are not all that commonly held in stock..was it actually taken out??? Other than that, it could be a wild coincidence...since I can't hear the sound I can't advise further, so it might be a good idea to go to an car aircon specialist for further advice...perhaps before you go to your filter changer????

Hey, I have a 3L 2003 d22 turbo diesel navara. It's revving at 3000 rpm when doing 110km/h and chews about 16l/100km. This seems unusually high to me. Just wanted to check of that is typical for this model car? Thanks
Have you just bought this vehicle? If not, has the operating parameter changed from normal? John Smith from New Zealand
And, as always, get the trouble codes in the computer read...... John Smith from New Zealand
Thanks for your response. In answer to your questions, no, I've had it for a while. No parameters have changed. Just thought I'd ask the question as I've seen threads on other forums where people reckon they've managed to get 600+ km out of a single 75L tank of fuel on the exact same vehile... I'm lucky to get 500km from a full 75L tank even when cruising on dead flat highway the whole way, sitting on 110 km/h the whole time. (Yes I live in the middle of nowhere so this is possible). The only thing I can think that isn't factory spec are the tyres which are currently 255/70R16 where the owner's manual specifies 265/70R16s. However this wouldn't have an effect on the odometer readings as the only difference in dimension is the width of the tyres. Again I ask, is this sort of fuel consumption i.e 15L/100km and revs of ~3600 RPM at 110km/h typical for this model? Thanks Dan from Australia

Does my 2014 Navara auto 2.5 4x4 have a good auto trans cooler standard? I will be towing a 2t caravan. Thanks Mal.
Mal, I can't see your vehicle, I can't open the bonnet and look in front of the radiators, (engine and aircon) to see if there is a secondary auto trans cooler fitted by the dealer when you paid for your new X-Trail. Please go back to the dealer and ask the salesman to show you any such cooler. If he can't or won't do this, book in your X-Trail at that Nissan dealer to have that dealer workshop fit one, after getting in writing that this will not invalidate your warranty, this way if something happens the cooler has been fitted by that workshop and you have in writing that the warranty still applies...get my drift?

Hi there.. I made a big stuff up this morning, petrol instead of diesel in my 2006 d22 str (3.0 TD) Got around five km down the road and it died. Have been told that a new fuel filter and draining \flushing the lines would get it going again. The only problem is draining the tank, I can't for the life of me syphon the bloody thing. Is my only option to get it on the ramps and drop the tank? Cheers!
Frank, do you have access to any sort of pump that you could attach to the fuel line before the filter (or just after) and suck it all out? There may still be some left though right at the bottom, and if you do get it all out any crap will also flow through or block the entry to the line in the tank.....damned if you do and damned if you don't. You would probably be best to bite the bullet and take out the tank, then you will know everything is out, as well as the crap. Good luck, I'll keep my fingers crossed for when you start it again..

Take the tank out, otherwise either some will be left at the bottom of the tank anyway, or all the crap will be sucked into the intake and block it. Tank out, all happy! John Smith from New Zealand

Hello I have d22 yd25 2002 2wd turbo black smokes, hard to drive at same speed, it's like it`s over fuelling. Then you put your foot down a bit and it takes off and stops smoking. I`ve just had new injectors fitted but this has made no change. Any ideas? Cheers
Andrew, Have you had the trouble codes read? If not, now would be a good time to do so. If you want to trouble shoot this logically, then it appears up until a certain point in the rev range, the ECU is under the impression that there is more air going into the engine, (thereby requiring more fuel) than is actually occurring. Have you cleaned the MAF sensor recently? Can you inspect the ducting that carries the metered air from the MAF sensor to the turbo intake for any breaks, especially underneath or in a bend? Both these faults could give the ECU the "extra air" impression. Can you check the TPS (throttle position sensor) is working properly as well? Last but not least Google SCV (suction control valve) faults and see if this could also be a problem.... Did the over fuelling happen before the injector change as well? Or did the person doing the change tweak the performance of the injection pump? John Smith from New Zealand
