I am posting this for a friend who doesn't have online access.
She has a 2003 Focus 1.8td
Every thing works fine but as she is driving along the warning lights come on on the dash sometimes one or two sometimes all of them.
She also loses the speedo and rev counter.
She has taken it to a garage to be checked but they say they can find no fault.
Has anyone got any suggestions as to what the problem can be & how to rectify it.
