Yes. I'm planning to test that. How to test fuel regulator? Ok. What happens when I disconnect pipe to servo?

I have been looking for air leaks many times... I replaced some hoses which I found to be problematic.

Hi,I have a problem on Lupo 1.0 AUC 37kW with fuel mixture. VCDS showing error:17560/P1152 - Long Term Fuel Trim Additive Air; Bank 1; Range 2: System too Lean17573/P1165 - Long Term Fuel Trim Additive Air; Bank 1; Range 1: System too RichAfter clearing these errors they comes back in few days. In a month comes on engine light too. Last time I cleared errors I looked on oxygen sensors learning values: -6% on idle and +24% on partial load. The strange thing is that readiness is absolutely OK. Any suggestions? I'm little bit helpless at this moment.What have been done:- new oxygen senzor- cleared throttle body- replaced some bad looking hoses- cleared manifold preassure senzor- changed fuel filterPics from VCDS there: https://imgur.com/a/ZehuiX5
