Manually starting an active DPF regen cycle (not an emergency DPF regeneration) Shown below is the procedure to manually start an active DPF regeneration. This is not required under normal circumstances. Use VCDS to enter the engine module as shown earlier. Click on "Security Access" and enter the security code 12233. The filter traps the soot and PM while deposits of these materials form on the walls of the filter. When the collected material reaches a pre-determined level, sensors monitoring back-pressure activate the filter regeneration process. The regeneration process occurs automatically when the engine is operating at optimum high temperatures. GolfTDI1. DPF was replaced less than 20k miles ago under warranty with EGR filter. Several thousand miles later, wire harness for exhaust temp sensor #4 was damaged setting a code for the sensor and preventing active regen of DPF with MIL. Took me a little while to get this fixed. Before getting fixed, exhaust flap intermittant failure, then The Easy way to check how blocked your DPF filter is Soot & Ash Level Mercedes.

The last regen started at 509 miles. The DPF Soot gauge before last regen was at 3.0 g/l and dropped to 1.53 g/l after regen. One other thing that concerns me is the DPF DP is 39 psi. MPG has increased some since using Motorcraft fuel additive. It seems to me that the filter doesn't get a thorough cleaning. The filter traps the soot and PM while deposits of these materials form on the walls of the filter. When the collected material reaches a pre-determined level, sensors monitoring back-pressure activate the filter regeneration process. The regeneration process occurs automatically when the engine is operating at optimum high temperatures. How the DPF Regeneration Process Works. The DPF is designed to capture soot particles over time. When the filter becomes too clogged, it needs to be "regenerated" in order for it to continue functioning properly and save your engine. Regeneration is a process where the pollutants are burned off in high-temperature exhaust gases. 6.7K. 2.7M views 6 years ago.
