Awesome and it works.
Worked great for Me. It’s for advanced diy and requires a pump to spray inside the dpf. Very pleased. Will probably repeat process this year.

Not an additive
I assumed this was a liquid additive. I added it to my fuel tank. There were no description in the listing so I made and assumptions, there also were no instructions on the bottle. My car has been running terrible and I have had engine lights coming on hopefully I can keep topping up my fuel tank and dilute it down enough.

This stuff works
This stuff worked to clear 2013 VW DPF that was throwing the P2002 code. Pressures after using were both less than .5 psi, indicating no restrictions. I modified a pump strayer wand to go in thru the 02 sensor instead of paying $600 for the recommended sprayer. Make sure to also use the purge. Unplug the Mass Air Sensor to prevent the liquid getting drawn into the intake and hydro locking the engine. I sold the car soon after to a friend and he's still without issues
