coolant temp sensor looked fine if it was right block but air intake sensor show 29´C and outside was 15´C (it has new maf)

also Group 001, O2 sensor before cat were -20% to -15% on idle with 63´C engine temp, vagcom normal values (-10 to 10%) but maybe engine temp was too low and these values just show that its running rich
