Tiguan in limp mode

This is what happened last night. Tiguan went into limp mode. Checked my gauge, nothing seems abnormal (strangely there is still boost), oil and engine temperature are ok, but I've lost the power and the spooling sound from both cold air intake and k04 were very loud. It felt like the car is getting the air but it went straight out of the car instead of into the engine. Called the RACQ and this is what the diagnostic tool says (attached)

Does anyone know why? Something fell off or blown? :facepalm:

Probably could be a boost leak. Check the intake piping etc.

Yeh. Sounds like a boost/air leak

Ill second the boost/air leak. Check that your intercooler pipes are still connected.
