This is normal if the engine is doing that . Coolant temperature up Hot coolant then oil pressure drops . But if it returns it could be short in the loom . Fuses would be my first port of call, along with earth leads ti the body .

Thanks for your reply. It happens hot or cold,a tap on the dash and all gauges return to normal. I will check the fuses and earth leads.Regards Phil.

Haven't you just answered your own query there?
If a tap on the dash cures it (as it used to with my wonky temperature gauge), how can it possibly be a fuse or earth problem?
Source yourself a serviceable triple gauge and swap it over. Easy DIY.
