Welcome to the forum.. The 1st thing I would do is change the fuel filter and also change the oil/filter if you have not done this in awhile. Also add something like Diesel Klean or Stanadyne additive to the fuel.. and see if it will fix the problem.. I am sure someone else on the forum can suggest other things that might be causes your surging.. Just a note.. My engine was surging and romping when cold and I switch from dino oil to Shell Rolletta T Synethic 5W40 and all my romp romp went away.. Engine runs smoother and quieter now..

I have a similar surging problem. Took it to the dealer today, no codes, nothing showed up on the diagnostics. They suggested a new fuel filter and a injector flush to the tune of $341.00. I told them that I just replaced the fuel filter a week ago. Asked them what if I sprung for the work and that did not fix it. No answer.. They grasp at straws at our expense. I still have about 15000 miles left on the warranty. I will put some of the cleaner concentrate in a couple of tanks and see if it goes away.....or drive a little faster

Injector flush is useless on our diesels. Don't go for it. You'd do a better job cleaning the injectors by running a tank of bio diesel than anything else. Good thing you didn't waste your money on that.
