So I just pulled my codes finally...2111...what's the next logical step?
No start condition, when it last ran it ran great except toward the top at around 20 psi (MTM 1+) it would miss. Ignition switch is new so thats out, I could swear i don't hear the fuel pump prime though. Is that the next logical step?

2111 code info from SJM's website.
2111 (Blink Fault Code), 00513 VAG1551/2 Fault Code Number
RPM sensor (G28)
Open or short circuit, sensor malfunction
Defective sensor & cables, metal fragments on flywheel teeth
Symptom: Engine will not start, misfires, may stop running
NOTE: I (Scott) have seen this fault code occur after cranking the engine during a no start condition
in a few rare cases where there was nothing wrong with the RPM sensor

The UrS fuel pump does NOT prime with the key just "on".The ECU does not fire the J17 FP relay until
it gets a signal from the Cam Position Sensor (CPS).<ul><li><a href="https://forums.audiworld.com/s4s6/msgs/149827.phtml">Link to FP Relay Function info in the FAQ</a></li></ul>

2111 might be real. Suggest swapping in a known to be good G28. Link inside

And then there is the possibility that your crank position pin went AWOL. See inside.
Crank position pins have been known to just fall off. Causes engine run/start failure. Need to pull the starter to check. (On a hoist or something so you can turn the wheels with the engine in gear).
