Yeah, I understand was thinking about the scenario when you bring it back to the UK. With the EML light on, usual practice is for the ECU to default to a 'safe' map. It shouldn't cause you any problems as it won't go so lean due to what the lambda sensors are showing post-cats as to cause any damage - it will have been programmed to recognise the most likely scenario where pre-cat lambdas look fine and post-cat are way off to recognise the cat is the cause.

To stop EML without cats involves flashing the ECU to remove the post cat lambdas
