1) buy MHD superlicense for that car it’s modded and should be running a stage 2+ tune (which will disable the CEL for the dp which is your goal)
2) use the MHD adapter and scan for codes. You will see any issues not just the dp code it will give you a full list.
3) look into common maintenance on these cars and just do the big ones right away preventativly IMHO because every car will need water pump, OFHG, Valve cover and gasket, injectors if you are running an old revision, just do the plugs now and have the fcp warranty for life on them anyway, walnut blasting. There is likely more but off the top of my head those are the things that EVERY n54 will need eventually especially at that mileage unless you’ve got good proof something on that list was done, just do it.
4) enjoy one of the best cars ever made once you get through the mountain of stuff it needs to be happy.
