hello, I have a 2014 VW Sportwagon with 122,000+miles and I have repeatedly had the diesel particulate filter icon light up over the past 4 years. The first time it occurred I researched it online and found this site. I tried driving it at high highway speeds to burn the matter off, but it didn't work. I took it to the dealer where they were able to regen-burn it off. It occurred a few more times and each time the dealer was able to burn it off. Two weeks ago I was driving home from my kid's house (2.5-hour drive- all highway) and my check engine light came on. When I took it to the dealer I was informed it needed a new diesel particulate filter and it cost (with labor) $2400.00. I am suspicious that since I was just over the warranty mileage of 120,000 that it now needed a new part when it was covered previously and they just burned it off. In either case, I will never know. These cars are expensive. If used cars weren't so costly, I would be looking for another car right now. The problem is that I do love this car. It still drives like a dream and the cargo space is just the right size for me to carry 5-7 50lb. bags of horse feed.
Since diesel fuel is expensive now and many newer gas cars are getting better mileage, this type of car is losing its value and appreciation. Good luck with your decision.
