Roma tracking

[GingerMunky]

My car is noticeably tracking to the left, so took it to a wheel alignment specialist who use a Hunter machine. They have had three goes now at getting the tracking resolved but been unsuccessful. Each time the Hunter machine reports all green results, on all metrics. Unfortunately it continues to pull left. They weren't sure if it was something to do with the electric steering. Any ideas?

A fairly simple test is to swop the front wheels around and see it the problem still exists, as that will eliminate any uneven tyre wear that can cause the issue you describe.
