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 ...

30 minutes on the highway once a week may not be necessary depending on how you drive but I agree that is the best way to clean the DPF. If there is not a message on the dash saying you are in regen you should see an increase in RPM's while idling. At that time you should try to run highway speeds as soon as possible.
I usually down shift to 4th or 5th when I need to regen. After 15-20 miles I will pull over to check if normal idle RPM's have returned. If not I will run a little further.
After you try it a few times you will be able to set a pattern of how to do it.
