Default Knock Sensor Error & Height Adaptation

My M44 has been running rough recently. I am having some errors, I recently fixed a bad cam sensor it helped some and got rid of the cam sensor error however now I have a knock sensor error and a height adaptation error.

I went for a drive today, came and plugged it into inpa, the car sounds a bit like a truck or diesel and the cylinder smoothness idle shows

Cylinder 1 67
Cylinder 3 63
Cylinder 4 195
Cylinder 2 138

So either the Cylinder 4 & 2 and compensating for 1 & 3. or those are the problematic ones. Never had this before the bump and its been sitting for just 2 weeks.

Will the knock sensor 1 being bad cause this?

Will test the knock sensor values tomorrow. Whats the height adaptation error? related to maf?
