Solved DTC code P029921, boost pressure of turbocharger too low, this afternoon with a simple part replacement (000-153-11-59). Picture shows the old and new bypass valve and the obvious problem with the old valve. Really was a simple repair with just three bolts and one electrical connector. Didn't break anything, didn't lose anything, and didn't have to buy any other parts that I damaged replacing the original part. Banner day!
I hadn't noticed any performance issues. I suppose in a way it's a fail safe design and with the waste gate open it prevents the boost pressure from rising too high. The car has 193,400 miles.
