You might want to check with the guy that's been stealing them, sounds like he may have a few.

Yes you CAN live with the DPF and it's really not that bad.

Doesn't seem to matter how I drive or even if I complete a regen without interruption. They always come back within ~150mi. Only time I get respectable miles between regens ~400mi is when towing my 5er. Take the trailer off and its back to its usual self every 150mi or so.

It has been noted that leaky injectors can be the cause of the frequent re-geners. I would not be surprised in the least that you are the culprit of some leaky squirters.

Yeah, no ****. It's amazing at how much they put themselves through to avoid solving a problem.

I was in the same boat, 100 mole regens not to mention it took about 60-70 miles to complete the regen. Once I got the letter in the mail about the 9th injector, I took it to the dealer I had been frequenting and basically stated my case and convinced them to change it. Since then, I'm seeing 250 miles between regens and it takes about 45 miles. Mpg went from 11's to steady 14.5's hand calculated.

If you are asking about the limited emissions tune that this thread is about then yes. It still regens but much less frequently.
