## Description

Dissolves typical contamination in diesel particle filters that can rob the vehicle of its performance

Review: 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
Review: lots of smoke, must be working - use as prescribed for DPF clean in diesel

## Questions & Answers

**Q: What is the difference between liqui moly 5171 and 5169? i have a mercedes 320e bluetec**
A: It's a 2-part system - the 5169 is applied first by spray nozzle and the 5171 is applied secondly as an activator.  Its used for the DPF filter.  Depending on your year of E320, it may or may not have a DPF filter.

**Q: is this something you put in your gas tank or is a wash like you have to take off the filter**
A: You have to spray into the filter directly.  Look on their web site.  They have instructional videos

**Q: How would i use this on my 2010 6.4 F250?**
A: Just write in YouTube ... there is a full explanation..
