2.0 TFSI error codes

Plugged my car into VCDS the other day as the EML light came on and performance was greatly reduced.

I got the following error codes:

Had a search on here as well as google and saw threads with regards to split in the n249 so bought a replacement one.Changed this yesterday and noticed my old 'C' version wasn't actually split or damaged (from what I could see), however I continued to replace it with the revision 'G' version I got from TPS.
Ran VCDS again hoping it would clear P2261 error code, but no joy its still there,
I've yet to move onto trying to fix the other 2 codes as I'm a bit confused about them. When I google or use RossTech's to check up on the error codes it all leads to timing issues with the cam.
Now back in December last year I replaced the camshaft/cam follower/timing chain/tensioner as I had a 'A' revision camshaft that had a heavily worn lobe which wore through the existing cam follower. This was replaced with the latest revision '2 piece' camshaft and as I had access and needed to remove the other components I replaced these as well.
Off the top of my head I would estimate I'v covered at least 5-6k since this work was completed and the car has been as good as gold.
My car starts,sounds and drives as per normal albeit the severly reduced power. This is what leads me to believe this error code is not due to the timing chain or tensioner as surely I would have some obvious noises from that area,or even the car would not start/would run rough.

Could anyone lend any suggestions as to what may be the cause?

Thanks all

Can anyone help?

audismart - thanks for the reply.
I have changed the N249 valve since the error code and MIL light have come on and still it stays. The original N249 valve (revision C), looked on good condition tbh with no splits in the diaphragm but I still replaced it with the revision G version I bought.
Today I replaced the camshaft sensor, did a scan after and still the codes remain.

As mentioned the car had the timing chain and tensioner replaced last Dec along with the the intake camshaft and has been running fine since Monday. Then al of a sudden up pops this error code and the MIL light and it's definitely in a limp mode.

audismart - codes have been cleared but still reappear.
Engine is a TFSI. Cam follower was checked late last year and a hole was found. Upon more investigation it became clear I also had a revision 'a' one piece intake camshaft. This was all then changed in December last year with a 2 piece camshaft, new chain and tensioner etc.

Thought'd I better update this thread.
I had the car looked at and nothing appeared untoward and everything was correct. Garage did a reset of the codes and MIL light was gone and car was back to being fine.
This is until this morning when I started the car and the MIL light has returned.
I'm pretty certain it isn't anything mechanical however one thought has crossed my mind. This year I've done probably double my normal annual amount of miles and at present since it's last yearly service maybe 10-12k has passed.
Could it just be that the oil is up for renewal?
It's serviced once a year but normally my annual mileage is circa 6-7k however this year it's exceeded that. Never had this light or these codes appear before and this is the only difference I can think of that's occurred.

Well today I did the car's yearly full service. Came to changing the filter and looks like the old filter has collapsed on itself. As I removed it from the housing out came the plastic cylinder that it rests over as well. I had to pry the old filter off this plastic cylinder and in doing so the filter just cracked and split!!!
This has newer happened before and I'm assuming because the car had much less miles in between the service.
As mentioned this year I've done an unusual amount of miles compared to my norm.
Touch wood this is the cause of the MIL light coming on and the correlation error code cropping up.
