W212 E250 Sluggish

[RSTurbo50]

Recently acquired my 2015 E250 CDi with just 62k miles on the clock. The car runs like a dream and is super smooth. However Iv noticed that once the car is warmed up, say you’re at 60 on the motorway and floor it, the revs rise and performance is mega sluggish, really struggles to pull and feels like a flat spot. I know it’s not the quickest car on the road but something definitely feels a miss with it…

Any ideas?

Check for fault codes first, usually swirl flaps seize in the intake manifold
