Engine surges when accelerating

Hi I have a 2015 CX-5 2.2L Skyactiv diesel manual, owner for 3 years. Really pleased with car.

For the last 2 weeks I’ve been having problems with the accelerator. Rickover’s is fine but when driving and changing gear the engine surges by between 1 and 3 thousand revs.

I have changed the MAP and MAF sensors and cleaned EGR valve. I’m not getting any codes showing up on OBDll diagnostic scanner so I’m stumped any one hade same problem I would be glad of bit of help Please!

Just one other question, does the EGR valve have any moving parts? When I cleaned mine, could not work out how it actually worked.

Any help would be much appreciated.
