cam error codes

[vala]

Plugged my car {'56 Octavia VRS TFSI) 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
