Audi A6 - car pulls consistently to the right.

[DC64]

A6 C7 4G 2014

When driving in a straight line, car pulls consistently to the right. On acceleration the car will pull to the right. 

When driving over uneven surfaces the car will jerk the steering in either direction. Issue is more noticeable at low speed but still present at higher speeds. 

Slight delay or notch (loose not tight) when turn from one direction to the other. 

No play in tie rods and all bushings are tight after multiple checks

Even tyre thread. No bent alloys.

Lower rear control arm + ball joint replaced on left and right

Drop links replaced left + right

Steering tracked

Any ideas as to what the cause is - I am stumped.

Have you had a diagnostic check to see if any fault codes flag up regarding the steering rack?

Hi Steve, this is my car the OP created the thread on my behalf. I have scanned the car multiple times using OBDII on 2 different scanners. There may have been one related to steering 12 months ago, prior to the current issuse, which I cleared and has not returned. I am considering buying VCDS just to see if it throws up anything. You suspect steering rack?
