Hi all! I have a recently purchased 2007 Audi B7 with the BPW (PD) engine that is having the dreaded overboost issue along with a general sluggish behavior. Turbo was replaced 40,000km ago and seems to be working ok. No shaft play and almost no oil in the intercooler. I have pulled a ton of logs and will post them soon. First I just wanted to confirm that the turbo’s actuator arm movement looks correct in this video. Actuator arm was engaged using the VCDS output test. I also detached the actuator and the lever arm could be moved smoothly and evenly. I just wanted to confirm that the vanes seemed to appear free before I started checking other parts. N75 and MAF are next on the list. Thanks!!
