We have a 299d2 xhp 2015 model bought it new and the first 250 hours car changed out the entire regen system but let me add that was one part at a time because they could not figure out why it was not regenerating, next the machine started bogging down so cat changed out the engine well that didn't fix it so they changed out the hydraulic system so basically at 1400 hours we had a new machine , a 150 hours later the machine is back at dealership for the same issues I believe I've taken it at least 20 times in the 1600 hours I've put on the machine. This machine has done nothing but stress me the heck out . I'm done with it.
