A regen with take about 40 miles. Any time is is stopped it will have to restart again. Go out on the highway and watch your mileage. During a regen the mileage should suck compared to what it normally is. Once the region is done the mileage will go back to normal.

As for your other question doing a delete is ok as long as you don't have any warranty left. You can bump up the power as well but then you will have to do upgrades as well including head studs and pump. Most will delete the egr as well. If your under warranty still this will void it. Go onto the duramax forums and do some research for more info.

1) Regens are time based (~30min) not mileage based on 2011+ Dmax trucks.

2) Head studs are not needed on a Dmax if running stock turbo. Its not a 6.0 Powerjoke...

Wow... If I had to drive ~30 min to complete a regen I think I would dump that truck. Mine completes a regen ~10 miles. And if I stop during a regen it will not restart the next time I drive the truck, but rather it will go a shorter distance before the next regen.

First figure out your warranty. It's 5/50...7/70 depending on what's wrong.
Second, 2.5-3 hrs shop time to do a regen is robbery, so I'd sort that out before going further w that dealer, unless they did more than that.
Last, in general, LMLs are generally decent preforming emissions systems. No tell what the cause is from here, but they can handle more putting around than the LMM engine emissions. But you still have to drive it long/hard once in a while. These diesel emissions systems aren't completely idiot proof as we would expect with 21st century stuff.
If you can delete it, it will perform flawlessly, like an old pre 08 truck, if emissions testing isn't a concern.
You'll need a private shop not the dealer to do it, if you're not planning on doing it yourself. Check out diesel place.com to learn about deletes.

I mentioned the same to the OP in another forum and the EPA fear mongers came out. Get "reported to the government"...."$500,000 fine"...and on and on.

Try to take it out for a good drive on the highway for at least 30 minutes. That is suppose to help.

OP, I would go back and see if this charge is correct.

The problem is, who do you go to? The service advisor? I never met one that didn't lie more than a politician. :R He is going to tell you that the charges are correct.

You might open your OM and read up on emission warrantee for you vehicle. That way when you go in you might have a little ammo.

Good luck!

I always thought Federal emissions warrantee was good to 80k/8 on any vehicle in the US?

I haven't checked on it in forever. Was that changed?

According to my BIL, the Grand Cherokee diesel he has does have the feds 80k mile warranty for the emissions.

I think for diesels it's 150K.
Either way this should have been covered by warranty.

I have my 2011 duramax, 60K miles in the second time in a month for the cleaning exhaust filter message coming on and not going out. First time they said it needed a manual regen. Cost me $300. Don't know this time yet. Anyone else have this problem? What did you have to have done? Anyone have the DEF and the exhaust filter removed and a different tuner put on? If so what did you get and how has it worked. Any other thoughts?
Thanks.

I had this happen to me and took it in and they found the injector for DEF bad. Cant remember the code. Get a code reader and see. When my F259 goes into cleaning it take about 20 minutes on the highway to stop.
