I started having problems with turbo boost yesterday when I left work; it has been intermittent since then.
Problem: I am only getting about 2 psi of boost (in all gears) most of the time. However, if I'm cruising along, let off the throttle, then get back on it, sometimes I can hear the turbo kicking back in and I will get my normal boost range of about 15 psi. I'm not sure what is going on. Could it be that the wastegate is stuck in the open position?
I would greatly appreciate any input.
PS- The Passat 1.8 is a dawg without the turbo. The car can barely get out of its own way.
After searching around here a bit and talking to a VW tech at a local dealership, it sounds like I am going to have to replace the wastegate actuator on the turbo. Of course, the VW dealership will only replace the whole turbo (at a much higher cost). I know the actuator can be purchased from ECS Tuning for about $170, but the question is How difficult a job is it to replace the wastegate actuator? I'm pretty handy and have done some work on my car and I also have access to a lift and plenty of tools at my work.
Has anyone done this themselves? How long does it take? Where do I start?
