Hello all. I realize this thread is old and hasn't been added to in the last 7 months, but it touches on some things I'm pondering and just hoping I can get some clarity from this group to help me understand better.
I bought my 2015 NMS Passat TDI SEL Premium August 2017, with 11,100 miles on it and after the selling dealer completed Phase 1 of the emissions modifications. At that time, the Extended Emissions Warranty extension was to be the greater of:
- 11 years or 162,000 miles, whichever occurs first, from the vehicle's original in-service date, or
- 5 years or 60,000 miles, whichever occurs first, from the date and mileage of Phase 1 of the emissions modification
For Phase 2A, according to the letter I received in July 2018 to bring it in for Phase 2, this paragraph of that letter applied to my situation:
- If you purchased a vehicle with the Phase 1 emissions modification already applied and your vehicle has accumulated fewer than 40,000 miles (for automatic transmissions) or 70,000 miles (for manual transmissions) at the time of your Phase 2 update, we will not replace the Diesel Particulate Filter, Diesel Oxidation Catalyst, and Selective Catalytic Reduction Converter in your vehicle at that time and we request that you return at a future date for its replacement once your vehicle has accumulated at least 70,000 miles. At the time of this service, you will receive a complimentary maintenance service with a free tank of fuel and have the aforementioned hardware installed at that time.
The warranty extension following Phase 2 was noted as follows in the letter received:
- 11 years or 162,000 miles, whichever occurs first, from the vehicle's original in-service date, or
- 5 years or 60,000 miles, whichever occurs first, from the date and mileage of Phase 2 of the emissions modification
My Phase 2A was completed on August 13, 2018, when the vehicle had 19,090 miles on it. The original in-service date was August 13, 2015. As such, my warranty extension would be, per the two items listed:
- August 13, 2026; or 162,000 miles
- August 13, 2022; or 79,090 miles
Item #1 is the greater of the two, so is my current warranty extension guide. My car now, as of February 23, 2025, has 147,500 miles on it. I also have 53.0 grams ash in my DPF (the trigger point built into the ECU to force a DPF change is 80.0 grams). GIven 53.0 grams ash is 2/3rds of the 80.0 gram limit, my predicted DPF life will be 221,250 miles (or 73,750 miles from now).
Given I'm within 14,500 miles of ending my extended emissions warranty, I'm thinking about getting Phase 2B completed. My understanding is that completing Phase 2B will extend my emissions warranty coverage an additional 5 years or 60,000 miles from the date/mileage that Phase 2B is completed.
Is this a correct understanding?
I also see in the Phase 2 letter I received in July 2018 that the Phase 2B update components are needed to maintain emissions performance for the full useful life (150,000 miles) of the vehicle. So now I'm wondering if I have a get Phase 2B completed prior to reaching 150,000 miles (within my next 2,500 miles).
Does anyone know if VW will provide the Phase 2B components if the car is in excess of 150,000 miles?
Lastly, has anyone had Phase 2B completed on their 2015 TDI recently (such as in 2025)? I'm just wondering if VW will even consider doing Phase 2B on my Passat anymore.
I would just like to canvas this forum to see what others have done and what is possible.
