Seems I have a navara issue just 10 days after the main stealer service at 18k. For some reason I get no turbo kicking in at all. That whole kick in the pants feeling has disappeared. Somebody mentioned the air mass sensor or something? Hopefully the dealer didn't overwrite the original map on the ecu. If they did, does a prochip remap get all the list torque and power back?

If the dealer reflashed it, you should still get the "pin in your seat" feeling, but just higher up the rev range.

normally its should kick in approx 1,600 rpm, but after dealer reflash its moved to approx 2,000 rpm.

No pin to the seat feeling. No turbo kick in at all. Just feels gutless. Needs 1500 plus to pull off then feels stuttery and sluggish until I hit 4000rpm. I think it must be something other than a dealer remap. Where do I stand if they did remap it and I didn't ask for it?

Nothing until you hit 4000rpm sounds strange?? even if they did flash your ECU it would still kick it at 2000rpm :scratch:

Yeah 4k is where it smooths out not really where power comes in. It's steady if gutless in gears 3 upwards, 1st and 2nd are sluggish and stuttery.

I believe the turbo comes in at around 1500 rpms so i would suggest the pipes to the turbo are loose!

I'll take a look at the turbo pipes but the main stealer can have it back, after all it was only 10 days ago it ran like a dream. It's horrible now, just got progressively worse since that time. Thanks for the advice. :cheers:

Dont mess with it then matey, just get it back to them and tell them to sort it, some lad had a similair problem if i remember right and the pipes to the boost solinod valve were on the wrong way round...... :shock:

either that or you have one hell of a boost leak!

only way a turbo will not run is if boost solinod is buggered, turbo/boost solinod plumbed in wrong, Boost leak, ECU not operating boost solinod to controll turbo correctly, or vains stuck inside turbo as the nav runs a Variable vain turbo.

They may have reflashed the ecu and the file could have been currupted......

the list is enless matey.... get them to check it!! :thumbright:

Just got back from the main dealer, and they claim the turbo is kicking in as it can be heard whistling. In 1st and 2nd if I progressively accelerate I cannot feel where the turbo kicks in, even though from there on in 3rd to 6th it does pick up of you nail it (though slower than previously). Have to wait until Thursday to find out if they did soften the power with a remap as the guy who did it is away on a course. Where do I stand if they did the download without my say so, and would a remap get past these issues...?


I really don't like driving the truck now, it's gutless and no fun at all....can't believe its the same truck I had before the service...wish I'd skipped the service now, f**king Nissan main dealer....

Yes a remap will sort it as its been developed using the orginal power band. But why should you have to fork out £400 to correct a fook up the dealer has caused!!!

Mine you, prochips also have my orginal file, so i would think they could just sort out the orginal stock file to run on yours??!! doubt they would charge £400 to put a standard file onto your truck....

ive just added this comment to my last post matey "Mine you, prochips also have my orginal file, so i would think they could just sort out the orginal stock file to run on yours??!! doubt they would charge £400 to put a standard file onto your truck...."

Well of they cant go back they will have to replace ECU and have correct file, thats what one member has had done! but not heard what the out come was.....
They have done summat to your truck that u didnt want doing or without your permission, the truck isnt fit for purpose anymore due to the way it drives!!!

In theory I could reject it as I didnt authorise the work..until they rectify the issue..? Do new nav's come with the original map or the softer map..?

I was going for a remap eventually, but not yet, and its a pig to drive at present...

thing is matey, what your saying your nav is doing, isnt that of what the softer map should do. the way the newer map works is the turbo is just delayed from spooling. so it comes in at 2,000rpm rather that 1,500-1,600rpm so thers less shock on the clutch and flywheel! thats the suposed perpose of the reflash to try and stop navs burning out clutches!!

so i recon theres summats a miss somewhere if your saying that power delivery is juttery and life less etc.....shouldnt be like that.

you could reject it as the truck isnt the way it was when it went in for its routine service. i recon the reflash has fooked up or they havent put summat back together right when they have serviced it.

I like the way the said the turbo is working cos they can hear it whisling! any turbo will whisle when reved as its drawing air in, but weather or not its working to its full potensal is other thing!!

Yeah I've never had a turbo vehicle before so I didn't argue with what he said. I will next time I see them. I just hope that running the nav in this state does not cause damage. I'm gutted that it feels this way. Ruined my brilliant truck. Oh well, I'll have to wait until Thursday when the service guy comes back. Thanks gor the advice, I'll keep you posted on what they say.

Keep us updated matey, plus i see your not to far from me in Northwich! Im in Northwich quite a bit doing jobs in the Macdonalds in the town centre there, which dealer are you using???

the local dealers to me are

Warrington = **** as its Fiat machanics that do all the work, as its a Fiat dealer and nissan have took over half the show room.
Widnes = OK but get arsey over warrenty work if the car hasnt been bought from them.

St Helens = Brilliant, first class service, very helpful, only take my Nav to this dealer now, plus its 2 mins from my house :lol:

Yeah we're 5 minutes from where you're working. I used twg Nissan/ Hyundai on the way out of northwich towards broken cross, past the rail station. I thought all would be ok with them, little did I know. Hopefully I'm not damaging my nav by running it this way as I'll have done nearly 200 miles by the time Thursday comes around. I might try st helens dealer next time..!
