Thinking my problem had been solved i was very happy, until the next morning when i started the car (first time) and the dash was off again.

I then jump started it and it works again... for now.

Can anyone explain this to me? is this something that a new battery could fix or is it possible that an alternator is faulty or a problem in the dash?

Id love some feedback on this because its driving me mad!
When you say the dash was off what exactly do you mean? were all of the instruments & lights off or were they jumping around with the lights flashing?

In my experiance the problems with the dash pod are caused by the Motorola chip (MC68HC908AZ60), this chip breaks down & is affected by cold temperatures. As the weather is now starting to get colder the problems you are experiencing could be this.

Have a read of my thread on the subject.
Laguna (possibly others) faulty instrument cluster

I'm a little confused by your post....does the car start & run? it only the dash that's not working?

Did the dash not working happen immediately when the car was jump started or did it happen later?

I don't think the Motorola chip controls the tyre pressure monitor...I'm not 100% sure of this tho.
