Hello, i bought me my first car for a couple of weeks ago. It was the 1998 A6 sedan model. I really enjoy my car, except i have this 1 problem.

The fuel gauge won't work, it will work sometimes just for a second, the car makes a sound when it works again and then i stops. More the heat cauge dosn't work all the time either. Same when it shows i have an warning with an injection problem.

But suddenly everything can be back to normal.
Anyone knows if there is something loose or just need the check out the fuses?
Is there anything i can do myself or do i need to troubleshoot at the workshop?
