Major problems

[Notoriousmib]

I'm having serious issues with my altezza, been going on for a while now and I can't get to the bottom of it. 

1. Fuel gauge light if flashing. Checked the sender and there is resistance from it. Everything else on the dash works apart from fuel gauge.

2. Abs light on and no traction control or Snow button functions. 

3. No outside temp display at all not even - - total blank. Also heaters don't work. The dials light up but have no controls but they do constantly blow out hot air. 

Anyone had similar issues or any ideas what it could be? Something has gone to cause all this but dunno what. I had to replace a load fuses to get other stuff back up and running bit these are the only things I can't figure out.
