To clean out DPF on TDI take it off wash it out water.
So can the DPF be cleaned up like that? So, what's the point of geting anxious about its regeneration, if one can simply clean it like that?

You want regen if not it will clog up.Then you drop the exhaust and clean out.Thanks for the welcome

Passive regeneration continually occurs when the exhaust gas temperature is between about 350 - 500*C. So, it's likely that during the 360 mile trip that the exhaust gas was in the proper temperature range for continuous passive regeneration (soot is being oxidized continuously). What we don't know is if an acitve or distance regeration was also initiated during this 360 miles. What we do know is that an active or distance regeneration occured at the end of an additional 200 miles.Interesting data I'm collecting.. We just filled up the JSW after a tank which included 360 miles of highway driving.
Question (rehtorical, perhaps) - it must have undergone a passive (?) regen at some point of those highway miles, right? Passive regen depends on exhaust gas temperature.
- So when we get back home, about 200 more around town (I don't baby the car..) miles through a week of time, up to 557 miles - we fill up with diesel, and a few blocks before I pull into my driveway (after fillup), I notice it's holding 3rd gear. So I knew it was under an active regen.
Do these regen intervals seem about right? There is no "right" answer. Is there a difference in effectiveness (in terms of amount of soot burned) of the two types of regens? Yes, see balance point temp below. Aka, two (that I noticed) regens of a different variety (?) are ok on one tank (of "only" 550 miles)?There is nothing to notice during passive regeneration.
Oh, and it was 93 F ambient outside, and nothing melted!!! I cracked the hood anyway
It would be nice to have a light that says when it is in an active regen. That might help more people not freak out when they get out of their car and the fans are running. I'm imagining a yellow (caution) or green (good) light.Bottom line: as long as the DPF light on the instrument cluster stays off, regeneration is doing its job. Drive more, worry less about whether your regens are about right.
The Vag-Com initiates regen is termed an "emergency" regen and should probably only be done when necessary (ie: when everything else fails). It probably would do no harm, but why bother.Has anyone performed a Regen with their VAGCOM? What was the result? What was your experience? Just curious how many of you tried it.
Going to try the "Dwiesel" method today to see if I can make the car do it on it's own. Will try and catch it with VAGCOM running.
My oil ash volume level increased dramatically so I'm not sure what's going. Perhaps the results from VAGCOM were prior to a regen? Has anyone noticed if the oil ash volume decreases (fluctuates) or does it only increase?
And just for poops and giggles.... would changing the oil have any effect on DPF data, regen cycle, etc. ? I'm sure there would be long-term effects like if you never changed your oil.
So when are you going to start selling them?It occurs to me that some enterprising TDIClubber with a good working knowledge of digital electronics and an understanding of the VAG bus communication protocol could prolly pretty easily design a small box that would plug into the dash port and illuminate an LED whenever "Regenerations requested" flipped from "3" to "4". This would be a pretty nice public service. I know I'd buy one (if the price was right, of course). Plugging in my laptop and wading through VCDS's less than elegant interface just to check the value of "Regenerations requested" after every drive is just too much like work to do on a regular basis.
I don't know if this counts as a "diagram", but here is a really neat thread with pics of a dpf dissection:Does anyone know where I can get a detailed diagram of our DPF system? I found a company that cleans DPF's. They emailed me back asking for a diagram and additional info. I'm curious what they are capable of doing... if anything.
You'll need an equity loan just to pay for the DPF alone.birkie- Thanks for the link. I'll forward this to the company I emailed. I might try and get a schematic or diagram from my dealer.
I hope the DFP's can just be removed and a new one installed without having to refinance my house to pay for it!
Regardless, it's a lot of work/labor ($$) just to get it out...birkie- Thanks for the link. I'll forward this to the company I emailed. I might try and get a schematic or diagram from my dealer.

Some of us might be considering plans that cannot be discussed as per the rules of this forum. Others might be waiting for a 3rd party equivalent, or a price drop. The going rate for an OEM dpf may not be constant over time.anyone want to chime in or is everyone hiding under a tree on this major issue....
besides setting off a code...at what point will we know if DPF is loaded and needs replacement? nobody in the world has come up with a way to clean these things out?I'm willing to compile data for 2009+ owners who have a VAGCOM or who can get their cars scanned. I'd like to see how the oil-ash volume is building up in these cars. If there is any other data that would be relevant I can track that also.
Oil ash volume can be found in group 108 or 241 in VAGCOM. Soot Load can also be found in Group 241.
Yes, there are companies in Europe who do clean out DPFs. There are also companies in America that clean DPFs in big trucks. The problem is that here in North America, there are relatively few CR diesels with over 120k miles. Therefore, there has been little need for DPF cleaning (yet). This will undoubtedly change as these cars get older (more miles). I expect that DPF cleaning will become more common in a few years. Those owners who put on a lot of miles will be the first to drive this change and the rest of us will be the ones to benefit from their experience.besides setting off a code...at what point will we know if DPF is loaded and needs replacement? nobody in the world has come up with a way to clean these things out?
I scanned mine this morningtdi90- I agree. I would like to see owners who have a VAGCOM start posting their DPF data. Miles driven, oil ash volume, etc. I'm real curious how other cars are doing as they age and get more miles on them.
This makes good sense. It seems as the need increases, we will see more DPF services that hopefully will not be exclusive to full system replacement (i.e. cleaning). It may be wishful thinking, but I do hope VW designed the system with serviceability in mind.The problem is that here in North America, there are relatively few CR diesels with over 120k miles.
