Hi all I have not used my s3 for around 2-3 weeks now and I drove the car today and the attached message popped up. So I have drove up and down the motor 30minute run each way at a permanent 2.5k revs and the light still stayed on I then thought I will put some fuel and call Audi the following day. I had half a tank of fuel while running up and down the motorway I then filled the car up and then returning to start the car and it was idling at 1300-1400rpm almost like how a diesel does a regeneration but with higher rpm. Does any one know if there are certain requirements that need to be met for the s3 to clean out the pod/gpf. Any input appreciated thanks
