I had the DV Valve changed  2-3 months ago. But the car feels under powered now with . I had the Fuel Pump Control Unit replaced as well, and that fault code is now sorted.

PCV would be next on my hitlist to check, if I were you.

The PCV isn't that expensive (~£29), fairly simple to fit and it is a known weakness in the MKV... It solved almost identical issues you are have, that I was having earlier this year.

Even new spark plugs might help.
