Ok i have a unique situation that i have never had before in any car that i have ever owned. I have an 09 R56 JCW and recently when i'm driving above 60 mph and in a right turn on the freeway, the car will suddenly drift to the left for a second and then correct itself and continue turning right, then drift to the left again and then correct itself. It only does this when going right, not left and will only do it at freeway speeds, never in lower speeds. When traveling straight or turning left everything is fine and it will stay straight so my alignment seems fine.

Anyone have any ideas what could be causing this?

 

Was the road surface grooved? could be you experienced a version of tramlining.....

 

Or maybe a bad tie rod end....I'd get the car on a lift and get it looked at asap.
Might be a minor issue...but could become dangerous IMO.

 

I wonder if it happens in Sport Mode or not, or both. Worthy of exploration that's for sure.

 

or a bad control arm bushing or ball joint.

 

Failed ball joint makes sense too....
