Hi, have had my Auris since 2007 and never had any trouble till now. Suddenly wouldnt drive either in auto or manual.Transmission warning light came on but no audible sound. Sat at the garage for a few days till the guy that looks after my car could get around to looking at it and it had decided to start wokring again!!!! which it did for 6 weeks and now has done the same again. It doesnt appear to be a mechanical problem but wondering about diagnostic testing to see if there is a problem with
