Diesel Particulate Filter cleaning solutions

OP here, thank you all for your feedback. I just returned from an 1,800 mile road trip with the SUV. Performance and fuel economy are good so, along with the repair, I'm assuming my DPF is clear. I also notice that the exhaust note is a little more pronounced. Since Mercedes deems not to share any DPF health information with their owners, these are the only parameters I have to judge whether my DPF is clogged.

I've done additional research on the subject. One third of Europe's cars are diesel and an entire industry has grown up around DPF clogging and remedies. I guess not so much in the USA as most of our diesels are trucks. I agree with the comments that a solvent based cleaner wouldn't work as it would flash off during the combustion process. There are many DPF cleaners in Europe that use Cerium Oxide as the active ingredient. This chemical serves as a catalyst and causes DPF soot to burn off at a lower temperature and keep the filter clean. All the chemical makers report it to be effective for city driving.

I've decided to give it a try and have ordered 5 cans of Liqui Moly DPF Protector from Amazon. This will be enough for a half year of driving. I've also committed to an hour's worth of 70+ MPH driving every other week. I will report back as to my thoughts.

IMO the moderators should can these types of posts, defeating emission controls is against the law, plain and simple. Don't like it, call D.C., and take the politics to another forum.

:R :R :R

A simple piece of correct diameter and length exhaust pipe and some computer tuning will eliminate all of those unnecessary emission related problems

My 2014 CTD lost nearly 200lbs of unwanted metal components within the second week of ownership. I am always baffled at the amount of people that honestly believe that because something is mandated by the Government and installed from the factory, it is magically for the greater good

Particulates and NOX are known carcinogens so yes, it is for the greater good.

Owner's manual.

I gave my DPF a couple good whacks with the owner’s manual. Now what?

Get a gauge that reads exhaust temperature, you'll know it's in regen when the temperature climbs significantly, if you can't tell by increased engine rpm's and tone. I have a Scangauge and that is one of the parameters that I read from the OBD II system while driving. There are other more sophisticated gauges, too.

I have a 2011 Cummins which has DPF but no DEF. These trucks are supposed to be bad for emissions issues but the only thing I have had is to replace a couple of O2 sensors (touch wood). That said, a lot of my driving is highway and towing. Working them and keeping the exhaust temperatures up seems to be the ticket for keeping the DPF healthy.
