The first 3 are exceptionally familiar ;-) the fourth is because you scanned with the ignition on
The first one is because like me you have a wide throttle body so the idle speed adaption chokes and throws a fault code when it can't get the idle speed within spec. I thought you said you had it idling normally at ~800 rpm ?
The second occurs when the ECU panics and kills the FP relay, causing power to be removed from sensors. This is accompanied by a feeling that you hit a brick wall. I seem to recall you didn't have enough fueling for the boost and it was causing bucking ?
The third is because you revved waaaay past redline, sorry the local Audi dealer won't be fixing your car under warranty.
The last is simply because you did the scan with ignition on, but engine not running, so no rpm's so the crank speed sensor signal is gone.
