turbo actuator
« on: 04 August 2012, 17:19 »
hello. right ive got a mk4 1.8t agu with a k03s turbo standard actuator got a few running issues boosts alover place somtimes and its rather jerky through the revs when under full throttle.  should you be able to move the actuator? been told yes and others said no. ive gone asfar as pushing a bigish screw driver against it and it still wont move put some wd40 on it and it moved the slightest bit is this normal?

Yes with effort you should be able to move the rod on actuator.
If it pulls quite easy then the spring is too weak.

managed to free it. wasnt the actuator its self which is seazied it was the bit that goes into the turbo if that makes sense? ahha :) got it warm lots of wd40 big pry bar hammer and it was free and it drives better than ever! boost is alot faster at climbing and seems to hold longer without the surging through the rev range, gonna buy a forge actuator still in a month just so i know its gonna be perfect then,
