Got two gauges playing up 

Oil temp sometimes slams straight over to 180 c before starting give it a tap goes back to where it should then creeps back to 180 will it do this if bad/lost connection ? Or bad dial?

Fuel gauge only reads from 7/8 of a tank to full no matter how far I drive this has happened recently was perfect before.

I wonder if this is a fault with the instrument cluster. You can send it off for an assessment and repair. Repairs usually are around £200-£300

Thanks Steve will look into that think the oil temp gauge itself is faulty if I got another dash can I open up mine and swap the gauges?

The oil temperature gauge issue could be due to a faulty sender. Similarly, the in tank fuel level variable resistor maybe at fault or sticky. 
Not absolutely certain with your c30 year old model, but it was very common to encounter a voltage stabiliser on earlier vehicles. This small unit was generally in circuit with the gauges and served to ‘damp’ the gauges - by lowering the voltage to c10 volts. Well worth checking the circuit diagrams.

think its definitely the oil gauge as just a little tap on the screen in front of it makes it return to normal reading tho some days fine others all over the place.

will remove and test the fuel level sender when i have time but think finding a replacement not going to be easy

 

The clusters can't be swapped out easily as they have the imobiliser built in.

Can the dials be swapped over ?

 

You can have the cluster repaired for about £300
