Drive now the 3rd diesel with DPF , my Opel and Ford were so loud during the regeneration , that it was easy to recognize and just drove one lap further to get the lead done not to cancel the Doesel or the regeneration not prematurely . The Kia is so quiet that I don’t hear it , even the consumption does not go so much up that you could use it as an indication . Driving professionally lkw since we indicated the burnout advance so that you can run the engine sst. Such an ad would be nice if you could retrofit. Does anyone have experience there?
