Diverter Valve ("DV")? It actuates when coming off the throttle to recirculate the buildup of boost pressure from the turbo. If damaged, you can vent boost pressure constantly when accelerating, causing an unwanted loss of boost and therefore loss of power. The rubber diaphragm can tear over time, more likely with earlier revisions of the part, the newest "revision G" is much better. If yours is actually damaged, you should feel a difference when its been replaced. :driver:
The other option is "PCV" (Positive Crank-case Ventilation) valve which manages the gas flow between various parts of the engine under different conditions (i.e on the throttle and off) and can cause a bad idle and loss of power if damaged. Again, due to a check valve wearing out. Newer revisions are much better.
This PDF is great for explaining these, and giving a general overview of our engine:

Going back a step in the url yield lots of other interesting PDFs too.

Hi,
Yes had both done. The DV and PCV. I had to have a different PCV as vw had non that were a direct replacement they were on back order. Definitely better. Miles more power
