Megane Scenic 2001 Monaco 1.9 dci Electrical Fault?

Can someone please point me in the right direction....
15amp fuse feeding the display keeps blowing, problem is when it does the speedo, fuel gauge, rev counter, pedometer all drop out at once. Other warning lights are fine, i.e. indicators, backlights etc. Is there normally a common problem here?
