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?

That KMS equates to less than 100,000 Miles - surely it should not need a CAT at that Mileage.

Any other suggestions apart from Cataclean?.
