Thats no Moon, Thats a space station!
After putting my sports cat on my car I got the light on the dash which I could clear but would come back after 10mins.
Got one of the lambda spacers off ebay for not too much money and it made the light stay off. I then got my software upgraded a few months later which coded out the light so have now removed the spacer so can confirm they do work.
