Claas Celtis 446 Hydraulic oil pressure light

[95xpower]

Hi Folks, i have a celtis 446 and when it's warmed up and I'm on the road the below No.13 like flashes once it starts to go up a hill.

Once i start to go down hill it goes off.

The light isn't full on but it's flickering.

Previously it has done this then would drop into the low button then I changed all the hydraulic filters and oil which cured the dropping down the half gear but the light now still comes up

Just to update i got this sorted, it was the hydraulic switch that was faulty.

So i replaced it and it cured it
