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.. ## Customer Reviews ### ⭐⭐⭐⭐⭐ فرق الاسعار *by I***L on 14 December 2025* كجوده تعتبر شركه liqui moly من افضل الشركات ولكن الاسعار في السوق المحلي افضل بكثير عن اسعار الموزعين في أمازون ### ⭐⭐⭐⭐ ok *by C***R on 30 October 2024* Lite dyr, men verkar ha gjort en aning skillnad... ### ⭐⭐⭐⭐⭐ This stuff works *by N***T on 3 August 2025* 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 ## Frequently Bought Together - Liqui Moly 20112 Diesel Particulate Filter Purge Fluid, 16.91 Ounces - Liqui Moly 20110 Pro-Line Diesel Particulate Filter Cleaner - 1 Liter - LIQUI MOLY Pro-Line Diesel Particulate Filter Cleaner | 1 L | Quick cleaner | SKU: 5169 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/337745948-5171-diesel-particulate-filter-purge-fluid-500-ml](https://www.desertcart.be/products/337745948-5171-diesel-particulate-filter-purge-fluid-500-ml) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-09-17*
