Error P0401

[poganyi]

Hi all, couple of days ago my car showned warning light:  Emissions control light. Car is Skoda Octavia III, 1.6 TDI CR, code CLHA, year 2007. Before it in september I used ProTec Diesel System Cleaner. 
 

Could you please help me, what is wrong or what I need to change to fix this problem.

 

Many thanks.

Also average consumption on speedways and highways is still more than 5 liters per 100km.
