Audi A4 won't start
 

I have a 2005 Audi A4 Quattro 1.8t with 158,000 miles. I was driving to work one morning and as I was driving the car just turned off on me . When it shut off it made a noise kinda like a really bad tapping noise . The CEL came on and it's throwing a P0011 ( Intake (A) Camshaft position timing over advanced (bank one ) ) Also a P0342 ( Camshaft Position sensor A circuit Low input B1 ) I bought a new camshaft position sensor and put it on and still doesn't start. Also bought a new battery just to see if that was the problem but it isn't . When you try to start it , all you can hear is the starter and the rpms never go over 100rpm . Sounds like it's trying to start but it won't . Please help , thank you .
