I have a 2013 Duramax with 130k miles. We’re in the middle of a 6k mile trip pulling 15.5klb 5er and I’ve started to get a turbocharger engine code (P2599).This first happened 3000 miles ago when I went to pass someone, caused the engine to go into limp mode at 30mph. After 20miles the nearest garage cleared the code and had normal operation. 50miles later GM dealer said might need a new turbo ($4k) or might be fine. After driving fine for 2500miles (traveling Rockies) it threw the same code on an uphill grade, again going into limp mode this time 20mpg. I cleared code myself and took it to Chevy dealer 100miles away. Same story, this time they said if replacing turbo they would recommend some other things as well ($6k). I drove on. Yesterday after another few hundred miles it threw the P2599 code but didn’t go into limp mode. After a couple engine starts the idiot light has turned itself off. Heading to Tetons tomorrow, still have 2k miles and a month to go on this trip. How worried should I be? Assuming it continues to behave like this do I need to invest $4-6k and a week+ in the shop? On the road? When I get home? Or do I continue to just clear code if/when happens again and keep driving?Thanks for your opinions, and better yet similar experiences. Ron

I can't answer your question but you might get better help here:duramax forumGood luck. Hope it's something cheap and simple.

There are several good options in Idaho Falls if you need help. Two of them are independent Diesel shops (Adrenaline Diesel and Powerlab Diesel). They both know these GM trucks inside and out. I also have a positive relationship with two Chevy service departments in the area. If you have an issue say something and I can help you out.

I had a friend with a loose clamp on one of the hoses and was losing boost. He described somewhat similar issues. I asked him to pop the hood and all it took was a couple turns and it tightened it enough to get him 350 miles to home.That is something easy to check.

Sounds like your VG actuator is sticking or failing. This is the exact reason why I replaced mine with a fixed geometry turbo. If this is the case, you can keep clearing it and hope it will last until it actually fails without any harm to the rest of the engine. When it actually fails you will notice it because you will have no power.

I had the same exact issue. Problem was a boost leak caused by a loose clamp where the intercooler hose connects to the turbo. Check the nut on that clamp before doing anything else.https://www.duramaxforum.com/forum/11978106-post5.html#/topics/909297?page=1

I accept your concession.

Are you just trolling, or do you have a vested interest in people buying money-pit trucks? Do you own a diesel truck repair shop, perhaps? DO you sell some sort of snake-oil miracle product?

This is exactly what he's talking about. Dude, sometimes it helps to look in the mirror when you begin to think everyone in the world is wrong but yourself.
I lunched the transmission at 60k miles in my last gasser truck, yet never lost a diesel truck trans yet (knock on wood). By your theory, one should never buy a gasser truck then either. Guess we better break out the hay-burners again. Because there's no issues or concern with them.....right?

PS, if you're speaking tongue in cheek jarl, it's not coming across that way...

Nope. Not at all. It just catches my attention when I see someone banging out the same note day in and day out and calling it music. It sounds more like Yoko Ono to me. :S

We've never met, so I have to conjure up my own mental image. Am I close?

Anyway, your obsession against diesels seems uniquely bizarre. I've seen just about everything here, but I haven't seen anyone else with same crusade as you, which makes it ripe fodder for poking some fun.

LOL...
So will differentiating between early and later Tier IV systems as well as having just a wee bit pf common sense and knowledge about the proper use and operation of said vehicle. It sort of defeats the everything is the easy button and you can go through life as dumb as a post just fine theory, though.

Edit: Not meaning you specifically jarlaxle, but those in general that think they can get in anything, turn the key and only worry about the traffic and what's playing on spotify.

That said, I fully understand the conditions, limitations and greater propensity for issues. Heck, anything has a greater propensity for issues than the opposite, aka not having it in the first place removes all propensity for issue.
And there's a reason I jumped on buying a deleted truck last year. But most of that reason was the overall deal and I would have made the same decision if it wasn't deleted. Receiving the original system laying in the bed of the truck in pieces was just the icing on the cake. Would still been a good cake the other way around though!

That's ok, it's his standard answer. Pretty sure either his wife or dog ran off with a guy who drives a diesel, based on some of his posts! LOL

I was thinking the same thing. Maybe it's a childhood trauma. A stranger in a diesel approached him when he was young.

I've never seen such a one-man crusade against the evils of an engine. Definitely PTSD.

Naah, I just see how bad the new engines are. Pretty sure we managed to top $60,000 in repairs (mostly emission problems) on the trucks at work in six months! Diesel has jumped the shark.

Replaced with new turbo in February, not a rebuilt

Could still be a bad part.
