Liqui Moly 20112 Diesel Particulate Filter Purge Fluid, 16.91 Ounces

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

I know very well LIQUI MOLY they've good products. But DPF cleaner and purge didn't work for me. Maybe I was using wrong process. I will ask them again because cat cleaner worked %100. I will order again.

Awesome product. Have to use both for proper cleaning. OM642 platform.

I used it with water to totally flush my DPF after removing it from my 2008 ML320 CDI. Seemed to work fine - was able wash out all of the ash from the DPF after dumping in a bucket of this mixed with water for an initial soak (I capped one end of the DPF and let stand for an hour or so)

Not sure. Still haven’t opened it since it took a minute to show up by that time i had ripped off my old Exhaust and just deleted my truck

Excelente

I used and run a regeneration cicle, but it didn’t resolve the problem, maybe needs a scanner to restore or reset. So I just changed the DPF unit.

This magic liquid fixed my Mercedes Benz, thank you
