Did you get this problem looked at? The c1300 and c1310 faults? I have the same one but no light on the dash. I have searched and from what I can see the first port of call is check for leaks or defects like bulging hoses and the bleed. Looks like my car got new hoses (only own her a week) so I think a good bleed is a good start. If you have any more info it would be great.
