I'm not sure if further insight can be provided on this issue but I am having the exact same problem although engine is completely stock.
Due to the whole Covid19 situation, the GTI has been parked for the past few months. I've ended up putting fuel stabilizer and used a ctek battery charger prior to leaving it in this state (wife's lincoln mkx is the children hauler and became the de-facto daily driver). I thought it would be a good idea to still drive the GTI around the block after sitting for about 4 weeks and I ended up getting EPC with the P00AF00 error. Wanted to see if there was anyway on OBD11 to actually exercise the actuator to observe movement of the arm while the car is stationary?
Symptoms are,
- charge pressure actuator actual position starts off at around 12.5% and is initially stuck here which I believe causes the "static" EPC.
- charge pressure actuator specified position keeps asking for 95%
- I don't go into limp mode as I get full range of RPMs.
- I get some level of boost but I can't confirm if its the correct PSI that the engine is looking for. (not safe to check boost on phone app while driving...)
- first time I took the car out from sitting for 4 weeks, I got the oil up to temperature and then started to push the car. As I do this I see my charge pressure actuator actual position value slowly creep up in value and in about 20km of various forms of driving able to get it up to the 95% threshold and am able to reset the EPC from OBD11 and EPC stays off for the rest of the night.
Tried again a couple of weeks later and the same EPC pops up, decided not to retry the whole driving thing if this is going to be reoccuring. Decided to spray liquid wrench on the wastegate actuator arm for a few days like how the other forums suggest. Tried for a third time last week. No dice.

This likely won't get resolved until I get marching orders to start going back to the office for work but looking to see if I should start preparing to buy a new wastegate actuator or worse, a new turbo...
