Looking for opinions, thoughts, feedback on whether to have the "Phase 2" modification done on my 2015 Jetta 2.0 L Gen3 TDI DSG with currently 25,000 miles before it reaches 40,000 miles or after 40,000 miles. If I have the modification done prior to 40,000 miles, the Settlement Manual states the "Diesel Oxidation Catalyst" will have to replaced a second time before it reaches 150,000 miles. Which of the two choices is the better?
