OK just an update. I have a shiny Forge actuator sitting at home which I did take to be fitted but the rod was too thick. The hole on the waste gate lever needs drilling out to 6.3mm to take the 6mm Forge rod apparently.
Anyway, after that I had a coilpack fail. That's now been changed along with all the spark plugs. I also did the N112 bypass at the same time and put on a new N75 'F' valve.
Well, the car is running again but still maxes out at the same psi as before. VAG-COM still says no faults (apart from the misfire in relation to the coilpack). I reset the ecu and did a throttle body alignment.
The only things I'm left with now are fitting the actuator and testing the wastegate whilst there, and check for any leaks once again.
