   yeh mine failed on the same, so all i did is before i got it retested was to rag the fuck out off it in every gear to get the cat red hot and then it flew thro the mot

   you dont have to rag the fuck out of each gear, just give it a few blips in 2nd and 3rd a few times, that'll get the CAT nice and hot
   
   Make sure your car is warm before you do anything though

   Dont rag it just go on a long drive, make the temp go up and down a few times. I'd heard a bottle of redex in the tank can help also.

   Cat needs to be over 300oc to be fully working, as for sensors...ask them to let it tick over rather than fast idle...its common on saxos to fail on fast 2nd ive noticed! I just let them tick over tbh and threw they go... But this is against practice!...ask the tester nicely!
