Thank you so much for your help.
I did actually blow one of the fuses under the bonnet after carrying out some work on the rear winker. The problem started after I replaced the fuse.
A continuity test has now been carried out and the copper strip is broken.
The electrician said the copper strip had overheated and melted the pcb protective coat and that it why it shows up as bare copper.
I am now awaiting an "expert" to apply a blob of solder to bridge the gap and hopefully this might solve the problem.
