Ok so, I get an amber engine light come on. Codes read P0420 - catalyst system efficiency below threshold bank 1
Other code is P10000 / P1000 which I understand are manufacturers system checks codes.

I don't get any messages on dashboard just amber EML.

I have reset the codes now and light is off. But this is second time for this Cat system code.

I'm wondering if its something I need t get looked at, sorted?
