Toyota Avensis po420 cat efficency below threshold b1

Car: Toyota Avensis
Variant: 1.6 Petrol Aura
Model Year: 2005
Has anyone a fix for this problem without changing the CAT. I can reset / clear the code but it returns after 30kms. No other codes are stored or present. The Car is driving fine.

Wh. Thanks for that suggestion. I have now put the Cataclean in the Avensis - run it for the suggested distance - switched off the EML and it has now come back on again.No faults stored apart from the P0420. Any further suggestions.

Is Scotty Kilmers suggestion worth trying?
