Might help might not.
Mines a 325d N57 engine remapped Popped up with reduced engine power after similar speeds Cleaned intake and removed swirl flaps at same time (not sure which of these helped) But doesn’t do it any more…. Wasn’t much carbon build up at all though tbh Maybe pop the MAP sensor out and see if it’s carboned up?! |

Exactly what I was thinking, if you had it mapped, then gutted the DPF afterwards without having it remapped to suit, then this is your problem.

Check the EGR valve moves freely. I was getting limp mode as the valve was very sticky.
