Can you turn light off permenantley.Please help neil

EMU Light

I have what seems a similar problem with the same age van. I noticed that it would come on after I braked hard shortly after I had set off. problem. I have now replaced the air filter but have noticed that the problem does no occur when the weather is damp and the air is denser. I am now looking at the Lamda sensor.

The performance of the van remains good regardless of whether the light is on or off so the EMU is not putting it into any safety limiting mode..

Any suggestions would be appreciated
