• so before i take it to the dealer id like to try and figure out WTF is going on,
  
  the other day i had a 000564 code Boost Pressure Regulation: Limit Exceeded (Overboost Condition)
  
  I checked all my Vacuum lines, Actuator holds vaccuum, cant see any leaks in the Vac lines, checked all the intercooler tubing
  
  when i would drive, around 2200RPM the car would start hesitation and surging, i would hit 3300RPM and the car would take off like a rocket,
  
  havent drove the car in a couple days, today the car worked GREAT!!! went down to the store on the way back BOOM limp mode got home and scanned it. 000665 - Boost Pressure Regulation: Control Range Not Reached
  
  this is a 2006 Jetta TDI BRM engine code,

• Can you move the vane actuator? Pretty hard to reach on the BRM but can be done.

• If you look from under the car, you can see an actuator that closes off the egr path to the egr cooler. It should be covered by a fabric heat shield. The bushing often leaks and hot egr gases blow out coating surroundings in soot and causing low boost. It also tends to whistle around 2000 rpm.
