VW Polo 2004 Model

[Sfisol796]

Good morning All,

Kindly assist, I'm driving a vw polo 2004 model.
1. My speedometer is not working
2. Power Steering works for 2 seconds and then warning light appear
3. Fuel gauge is going up and down as soon I turn or apply beaks.

I changed negative cable on the battery, change Power steering sensor, checked fuse both on the battery and next to the door.

Please assist guys!!
