2006 fabia 1.4tdi not taking off in 1st gear on the ramp.  Where should I check?

Please elaborate so that we can help you, we need more information.

Araç yokuşdayken ilk kalkışda çok zor kalkıyor.

Rolantide gaza basınca devir sayacı yarım saniye geç kalkıyor.

Translated:

When the vehicle is on the slope, it is very difficult to take off on the first start.
When you press the gas at idle, the rev counter goes up half a second late
