Reopening this.
E300, did you get sorted?
Here I was annoyed with my only 13Psi boost pressure, I finally went today under the beast and moved the acuator for the wastegate a little forward, I am now on 15Psi :bannana:
I guess with the heat, the time etc... the acuator rubber inside loosen a bit.
I need to go for a proper drive tho. But 15 is better then 13
I wonder how much a new acuator is and if this could be your bugger?
I wouldn't mind changing mine for a younger fresher model ,I am talking about the acuator here
