Sounds like it's in limp mode. Or the turbo could be on the way out?

Hello mate what engine do you have? I have a 2.0 TDI and had similar problem. I cleaned MAF sensor didn’t work, changed fuel filter didn’t work, changed EGR valve didn’t work. It turned out to be a turbo boost pipe with a small split in it, did the job!!! Runs like a dream now. Sam
