Okay, I've a volvo XC90 and when turning right the power steering pump kinda cuts in and out and I want to know why.

Let me explain. If I'm turning a long 90 degree corner, the wheel will kick slightly about twice.
It's not the suspension or alignment as I've had that all checked out and re-done.

The pump itself works well at lower speeds or when parking, no noises or lack of assistance. I've changed the fluid as a precaution as well.

One thing that has happened is the ABS Service Light has come on just recently.
Now I'm thinking it could be something to do with the Yaw Control sensor (which would cause the cehck light on) which in turn may do something with the power steering assistance level, could this be possible?

Anyhow, completely stumped now.

Is there more noise then normal?

May well be your steering rack or pump. Prepare for a b*ggering down at the your local garage.

ETA: My old car's steering started feeling slightly less smooth than normal last year, and then a noise started. Turned out to be the rack leaking which all in all came to £2300+VAT for a new one.
