Just an update , The warning light is back on and staying on, so I rang the roadside assit and got it pickup last night.
The one good thing is that it is going to Highway VW at Springwood and the other good news is they have had the same problem with the Tiguan so maybe it will be OK.
They where amused that I had persisted with Nostral VW (cus their work and serivce stink), let us see what happens from here.
