'02 Freelander S Fault Codes

[Ninden]

I've had my Freelander only for a couple months and I've had some serious problems with it. About $1800 worth already. Tuesday, my engine light came on again. I went into Auto Zone to have the codes read and this is what pulled: P0430, P0705 and P1472. I'm not very mechanically savy and I tried to research these online and around this forum but none of what I'm reading makes sense to me. I made an appointment at the dealer (I got a recall letter on the fuel filter that they have to replace for me anyway) but they can't take me for two weeks. I need to find out if I should continue driving it until then. As well, I'm hoping to get an idea of what I'm in for price wise. Thanks for any help!
