I would check all the connections, if one of the boots are loose or half off, it would definitely cause problems. Does your turbo pressure gauge register any boost?

 

It does register boost.

 

Turbo actuator. Mine did it at about 30k. Replaced under warranty

ugh...I should read the whole post! I have no idea if that isn’t it!

 

Like @Bmw said- check all your intercooler fittings/connections. You could have a boost leak after the turbo.

Is the truck super sluggish? How’s it performing other than the CEL?

Had an afterthought- open your air box and take a look at your air filter. I vaguely remember a member on here that had sucked an ‘el-cheapo’ brand air filter almost into the turbo and was getting poor performance and low boost.

 

With the CEL on it ran fine till it went into limp mode. It sat over night till the tow truck came started it up and it ran fine, the CEL was still on. The air filter is a frame so not a cheep one. The dealership swears they are getting bad actuators from Nissan.

 

wakeinvol,
it all good dealership swears it’s the actuator, they are going on actuator number 3. They can’t get the CEL and 900AF to go away. Does anyone know if you have to tune the actuator for the turbo I kinda don’t think they are doing that

Absolutely, there is a procedure using the Consult software. That is what sucks about doing our own maintenance. Replacing that actuator is easy---easy access right out on top. But like so many things, you need the Consult system to finish the job! (uugh)

 

Update:
Third actuator still didn’t fix the problem. They have contacted the Nissan engineers to try to figure out what is going on with it

 

My truck is having the same problems, what was the final conclusion to your turbo problem?

 

Any update on your truck? Having the same problem and can't find an actuator anywhere. On backorder from Nissan. Hoping it is something else!

 

my truck developed the same issue about 4 weeks ago. Took to the dealer for diagnosis and repair. Turbo boost actuator cited as "probable" problem, but part on backorder. told me it was safe to drive, but after experiencing "limp" mode while in heavy traffic, it's far from safe.

 

Taking my truck in to replace the actuator today, now that they were able to get one after two weeks. I hope this fixes the problem, and it won't ever come back.

 

Sure hope they solve the problem. Mine's been sitting at the dealer for 2 weeks now waiting on word of an available turbo. Its a good thing I'm not in a hurry to go anywhere this year. To make things worse, i don't trust the truck to go back up north again.

 

The dealer replaced the actuator yesterday. No more CEL, and the transmission shifting now seems to be more crisp.

 

That sucks. The waiting on parts is what got to me…when my actuator went it was available. The turbo was intermittent and wasn’t an instant necessity but I still wanted it fixed. Had to wait for it to come in and finally got frustrated and just traded! Problem solved.

I do miss my XD though. If I hadn’t been worried about other issues I would have never got rid of it.

 

If you have been told that Titan XD engine parts are on back-order, you might want to register a complaint with Nissan Consumer Affairs. Contact number is 800/647-7261, Option 7

 

Upddate: Got the turbo in finally. the tech's had plenty of issues dealing with seized bolts and re-threading and so on but managed to get the new one in.
Truck ran great for a day or so and then went nuts. Fuel consumption went way up. All sorts of idiot lights showed up and when getting on the hwy the engine started shuddering like nothing I've ever seen it do before. Also got some transmission bumps. Took it straight back to the dealer ship and got a loaner and went home.
Got the call next morning, A connector had come loose and was the source of the issue so problem solved but not before the tech had to scratch his head a bit.
Truck runs like new now and is getting about 10L/100km which isnt bad. (empty). Smooth and lots of power again.
So a new turbo every 70km or so. Aint that just ducky?

Zurc.

Hey Zurc, where are you from ? Having problem with actuator issues. Its hetting out of hands, if possible i would like to talk to you. Thank Sylvain
