Diesel Particulate Filter cleaning solutions
My diesel SUV has just returned from the shop with a new DPF as the new one plugged up at 42,000 miles. This filter is plumbed right off the turbos and requires that a lot of the car is disassembled ...

I also have a 2015 ML250 which I assume is the vehicle you are discussing. I have done a lot of research on the same subject and do understand the high cost of the DPF when purchased through a dealer. I would look into finding a qualified independent Mercedes shop in your area or someone who does a lot of Sprint service work. The cost of a DPF replacement should be much less than through a dealer. A number of companies are using the Sprints and are getting over 400,000 miles of service out of them.
From what I have found, once a week might be overkill for a long highway trip but certainly the motor needs to be exercised monthly. As with a number of Mercedes parts, dealers tend to protect the price aggressively and they are kept high. Spending time looking for alternative sources of the necessary parts will be well spent. I have decided to keep mine and to spend what is necessary to maintain it, at least until I can find a suitable alternative vehicle which they are hard to match.
