    Might be the CAT or the Lambda probe. Or even the tempreture sensor telling the engine that it is still too cold. Thus the ECU will tell it to over fuel all the time ( like running with the choke on all the time). Thus are several possiblities to look at.

    It might not have been warm.. as ive only drove like 2-3 miles to the test center.. and had to waight for 15 minuts until it was my time...

    but when ive got the car back it showed about 85 degrees in water temp...

    Can i somehow test the lambda probe? or is it just about checking for error codes?

    I don,t think reading any codes will be able to tell you if the Cat is worn out though.
    We had this happen on the wifes Vectra B several years ago. I had put a new CAT on as the old one had fell to pieces. It failed on the emissions. Belive it or not the CAT was Duff/no good. They put another one on and it passed. I got my money back off the "old/duff" cat though.
    I wonder if reading the codes for the Lambda might show something though.
    When you say it might not have been warm. They should have waited untill the "machine" said it was hot enough, or waited till the tempreture gauge showed normal/working tempreture. Otherwise the car would not be measured at it,s "best working condition".

    Try some "carb cleaner"/ fuel treatment, then give the car a good drive, that might "clean it out" and help the emissions.

    Don't wear your slippers to the test centre Mr Ken.

    Make sure you have a fairly empty fuel tank, empty a load of fuel treatment into it. Give it a hard fast run, maintain high revs for a while. Then retest it.
    Now I need a turbo to keep up!
