Yup new steering rack then a new steering column, both fitted under warranty. Recently passed 1st MOT so all is currrenty OK. Steering became extremely heavy so a new rack was fitted, then a new column was fitted after slight notchiness felt through the steering wheel. This 'slight notchiness' has since returned and as I have now run out of waranty I have now assmed that this is (as MINI love to say) a 'design feature'
