I just bought a used 2018 with 20,000 miles. The threads are now scaring me a little bit. I am guessing that the vast majority of owners are satisfied and are not modulated to vent. Those with failures would naturally be more enthusiastic about their posts. So my question is I have heard about the ERG and it’s ability to get clogged with soot. Should cleaning it and the map sensor frequently be beneficial to avoiding engine failure?
