I am a new owner of an old Q7 TDI. It is an Audi exec lease that was turned in and had the "software update" applied for the TDI emission fix. My state requires that it be inspected and it failed for the Smog Check. I was told that the TDI fix requires that the vehicle be driven for more than 100 miles, and a set of pre-set samples. I have not been able to confirm that this is true and now the vehicle has gone over 100 miles. All the ODB entries are green except the PM Filter which says "has not completed test cycle"
Anyone know what the time or distance is for the "test cycle?"
