Other non pumpe duse mk4 TDI engines are similar. 2004-2006 mk4 pumpe duse 1.9L TDI, 2005-2006 mk5 Jetta, and 2009+ common rail 2.0L TDI use an actuator with a sensor to see rod position. A common problem with these is broken wiring at the actuator.

What should I do about my wastegate actuator?

One is that you increase the boost pressure needed to start opening the wastegate. The second is that you lower the opening range of the wastegate door. Increasing preload or changing the actuator with a higher spring pressure model (such as a Turbosmart pictured below) results in more boost!
