Hi all, been a while since my last post! Having a strange thing happen... When I refuel (generally to full) my engine management light comes on. This then stays on and goes off as I get down to below half way. Anyone had anything like this? I've been using branded fuel and not supermarket as I thought it was maybe a dirty fuel issue. Any ideas appreciated :D

Supermarket fuel is just as clean as branded fuel, only the detergents etc may well differ. You’d need a test rig or be doing thousands of mile to be able to note a discernible difference.
Not my thoughts, but it has been suggested previously that the fuel filler cap may not be seated correctly, there may be some sort of blockage or vacuum in either the fuel line or the expansion line to the fuel tank. Take a really close look at your fuel cap etc to see if there is a buildup of contaminants.
