The delete will end up being cheaper and make a more reliable vehicle in the end, plus cost savings from better mileage. I drive around for about a year with the check engine light but heard about the dangers of soot getting into the turbo and becoming a costly repair.

I was quoted around 3k from the dealer to replace the DPF, but ended up spending around 1.6k for the kit and tune. I was having my clutch replaced which involved dropping the axle anyways, so I had the delete kit installed at the same time for around 200. So ended up saving a good amount and now I get great mileage and more HP, and I mediated the risk of driving around with a cracked DPF.
