Hello, I own a 2007 w211 e220 cdi and I have some problems with it, firstly, the biggest one is that when I try to drive on the Highway the car goes into some kind of limp mode and loses like 90% of its power no matter the throttle input, I could give it full throttle and the car would still accelerate with 10% of its power, I went to a mechanic with a Star test and he diagnosed as the dpf filter being clogged, he unclogged it and the issue reappeared. I should mention that the car doesn’t pull like it used to, it still pulls but not with the same power. Another issue I have which is small is that sometimes at around 1800 RPM the car kinda loses a bit of power for a second before going back to normal. Any suggestions?
