Fuse 73 is one of 3 fuses used to control the radio/computer and is found in the boot compartment. The other day it blew and was replaced and worked fine for 24 hours. It then died again and was replaced and died again within minutes. Now I have an appoitnment with my local dealership to fix the problem but thought that, before I go out and spend what will ultimately be a small fortune, I should se if someone else had witnessed similar problems and could help. Many thanks for any response.....
