Good morning I have a 2016 a5 cabriolet, when purchased steering wheel buttons and paddles were not working but the horn was I have replaced the control ring under the airbag after diagnostic said this was the fault, however since fitting my mechanic can't get the cruise control stalk to work which was working before the control ring was swapped, I ordered a new part from autodoc using the vehicle reg so I'm sure the ring is the correct oem part, any ideas or advice would be really appreciated
