Multiple Codes...what are they

Just got a CEL on my 2012 Passat TDI. 120k km. Emissions fix done.

Got code:
8834
8842
8845
17606
7925

What kind of problem is this pointing too?

VCDS "save codes" output would help (text file.... post contents here)

Got the codes again. Here is the scan.
I've got the extended emissions warranty, but I don't want to take it to the dealer if it's something I can fix myself.

Looks like torque difference in 3 cylinders....

I didn't have any codes before the emissions 'fix'. Makes me wonder if it's some corrupted software. When cold, it does sound pretty growly when acceleration, simiar to the 1990 Golf diesel I used to own.
