2001 Disco 2 service engine soon light

[Robertino]

I worked on this car about 2 months ago and now this light popped up. It drives fine ....so i put my OBD2 on it to read the code. It said that there was 1code but it would not tell me what it was, it just said N/A ?
So I erased it and will be putting 10 miles on it to see if it comes back...have any of you had this before?!

Welcome to the forum. It depends on you OBD2 scanner, and how good it is. But the code could be as simple as the gas cap isn't tight enough.
