peugeot 407 instruments ?

I have a problem with some of the instruments on my 2007 Peugeot 407 saloon. The coolant temp gauge has never worked since I have owned the vehicle, and recently the fuel gauge started to work intermitantly, and then stopped working altogether. Also I have used about 10 dip headlamp bulbs in the last year or so.
Anyone got any ideas?
