Sorry, don't know what CEL is?
I did remove the Engine management fuse from the box for a while and this seems to have reset all the fault lights.
However, the Emissions message came back later, so removed the Emission system fuse briefly to reset it. It was good to learn that my fuel-low light comes on with about 40 miles left in the tank.
Tomorrow I may try removing the emissions fuse altogether, if that is an advisable thing to do?
What do you think?
