    Never heard of any of these failing. Common? Rare?

    Which parts DON'T FAIL on this car? Lol

    How does one know about this being an issue? Do they get stuck open and bleed off boost?

    I would guess logging the boost Request vs. Actual as well as the position of the bypass valve would give clues as to its functionality?

    I'm making myself sound dumb in this thread.

    I saw those two values in the 034 logger.

    I made a color-coded 034 logger, and I can make conditional cells to light up if there's a large difference between these two values.

    Pretty much always it will throw a code. On my car I've had a few failures, one stuck closed and put car in limp mode and another the potentiometer failed causing a code

    Just wanted to drop a line and let everyone know that Shane is a trustworthy and cool dude. Bought one of the valves off him and all went well. Easy to deal with and no bs or delays during the transaction.
