Boost spikes can occur from many different things, but I bet the combination of estimated value and volkswagen electronics are either telling you the wrong thing or the solenoids don't anticipate the boost pike and just let it happen. You won't really know unless you have a real boost gauge. I don't trust VWs at all.
Broken diverter valve would see spikes at throttle plate closure if it was broken closed (very unlikely), and would boost low/flutter at constant boost. Do a third gear pull log and see what you get.
