2008 Audi A4 B7 2.0T Quattro

Where do I even start, I'm so frustrated.
I have been having problems for weeks now.
First, I was having my CEL pop on at high RPMs with the code P2293, and the power would cut off for a split second over and over again if I held the peddle down. Almost like it was cutting off the turbo.
So, I replaced the Cam Follower.

Now, The power/turbo cut off problem I was having at high RPMs. I'm having that problem anytime I rev.
Also, I now have both codes P2293 & P0016

Here are the codes.
P2293 - Fuel Pressure Regulator 2 Performance
P0016 - Crankshaft Position Camshaft Position Correlation Bank 1 Sensor A

What do I need to repair?
And is it worth fixing?
Or should I just buy a new car?
Thanks!

 

Not sure about the P0016 but my P2293 code disappeared after I replaced the thrust sensor in the fuel rail, I think.

The reason I'm unsure is I replaced a few things around the same time.

Perhaps a connector isn't fully clipped in or is dirty/wet?

If I were you, I'd chuck a thrust sensor at it and clear the codes, see how she goes but that's not the politically correct way to forum repair a car so I never said it.
I digress.
