I don't have the steering knock. However took mine back to Lloyd, Colne today because of the knocking from the rear. It SEEMS to be from rear nearside and is prominent when that wheel goes over a small pothole or other undulation at speeds under 40 mph. Their top mechanic came out with me and confirmed he could hear exactly what I was on about......always a start.......and spent an hour with it on a ramp. Sadly they found nothing obvious so they have raised a PUMA case and I now await contact.

I have normal M Sport suspension, not adaptive.

Fingers now crossed!
