My guess is if you arent seeing the blue light and experiencing the side valves opening up earlier on sports exhaust mode then its possible the software updates have not been applied or the adaptation has not correctly occured. My car is an early build ROW and they needed to do over 130km of run in testing to get the new software patches to successfully optomise. I am not certain of the details in my particular instance but I believe they had to load updates in a particular sequence to get them to graft correctly. I have heard of a few other early build ROW cars that needed extended adaptation by the dealer after new engine install to achieve successful outcome.... Just a thought....
