I've noticed it before,but a lot more so today.
When pulling off, or at realy low speeds (1st gear) i feel a slight pulling,from the rear wheels.
Mainly only when turning,
It feels like the rear wheels are locking up abit/ not freely turning, and are being dragged a little. It stops as speed increases or i straighten up,(generally the two are hand in hand)
Im not sure whats causing it? I heard it could be because my car has the 18" RS4 wheels, and the haldex might play up abit because the standards are 17"
