2005 Audi A6 Quattro

[burdi65]

I have a 2005 Audi A6. I was driving home last night and the coolant started leaking... Also this morning I started it back up to check to see where it was leaking from and I now have a CEL on! The codes are: P0341 and p0366. The engine is making a knocking noise!!!!!!!!!!

I get this same problem today. Same code:
16750 - Camshaft position sensor not a plausible signal P0366.

No leaking coolant.

The engine is making knocking noise but that goes away when I shift to D.

Assuming this is a 3.2 = Camshaft position sensor (G40), and CP sensors 2,3,4 are bad or intermittent signal. Pop the hood and the G40 is right there on the left.
