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.

did you check your PCV?

did you check your PCV?

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.

Coil pack? Is is misfiring?
