From what I've heard and experienced, the WGFV typically craps out
"silently" (i.e., without benefit of ECU code). The failure is
frequently caused by a bad solenoid coil (winding) that keeps the
valve held wide open. This (open valve) is the "default" failure
mode, which limits boost to about 1.4 bar. There is an easy-to-do
solenoid resistance check (see Bentley) which will show up a bad
WGFV. You can also trigger the WGFV operation as one of a series of
ECU output tests (see Bentley); this test produces audible clicks
when it operates the WGFV. However, when I did this I heard the
clicks even though the WGFV was defective.
If you can find one (they were hard to locate a couple of years ago)
a WGFV costs about $80.
