Another day another fault code :lol:

P0430 - Catalyst system efficiency below threshold Bank 2. Now I’ve searched and am aware this sounds like a failing catalytic converter.

Now I had an o2 sensor replaced a few weeks ago which had to be moved slightly due to the original o2 sensor stripping the thread on its way out. So now there is an o2 sensor boss + new o2 sensor.

I don’t believe in coincidences, surely the above work has something to do with how the sensor picks up info from the output of the cat which is throwing up this code? Or am I just unlucky and they are not related?

On the plus side I have a warranty which will cover it, I think.

Any help and guidance appreciated.
