HELP!!! Exhaust gas values don’t fit!

Hello, I am slowly on the verge of despair. I hope one of you screwdriver gurus can help me poor woman. I drive an Audi coupe BJ89. It was a lot to repair when I brought him to the Ösi-land. Among other things, the exhaust gas values did not fit. Now the spark plugs, air filters and Temp.Geber were changed. But they still don’t fit! The mysterious is, however, when I come into the test hall (distance approx.10km) the car is warm. The examiner wants more. 5 times around the hall in the 1st gear (aua) Stengel again, exhaust gas values under every sow!!! We are with the Latin at the end… Please help me! A desperate Audi bunny
