I think my T4 has a rattling actuator arm, when you take your foot off the accelerator you get a metallic vibrating sound then when you apply the accelerator again it goes away.

I was wandering if anyone has had this before on here as I understand it is not an uncommon problem and is the result of a split D pin missing off the arm.

The rattle is normally due to wear on the wastegate pin and actuator turn nuckle, have you got low boost and poor performance too?
