DPF

[Vaszax]

Hi. I have a 2010 C4 PICASSO 1.6 HDI with 155.000 km on the clock and i think that the dpf filter regenerates too often. Is it likely to be full ( no engine light on the dash or any message)? Would you suggest to clean it or replace it? Could you recommend any good aftermarket brands of dpf's? Thanks in advance!

How often do you think it is regenerating / how do you know? 500 miles / 800km would be about normal, can be more often if you do lots of short journeys. Most aftermarket ones are not good...

I think it regenerates at about 500 km. I do mostly short journeys 20 km to go - 20 to come from work every day and 4-5 into the town. I can understand it as the engine work more rough and the mirrors are heating up during regeneration. My mechanic told me to go on s long trip so the dpf to clean properly.

Sounds about right for short journeys. A decent long run to get it properly hot might help, but I had a 307 that ran a little bit rough during regen - never caused any issues (aside from being noticeable!).

Before replacement or any work, the DPF should be diagnosed. ELM 327 with the FAP Lite APK program can be used for that.

There is also a more complex Lexia 3 diagnostic, for starters this simpler and cheaper one is enough.
If there are no warnings, then everything is still fine.
