Diesel Particulate Filter

[Umai Naa!!]

I'm not sure with VCDS, but with VAS-PC (The official software), you can't perform a regeneration on the DPF if it's over 90% clogged. Depending on the vehicle, and software version, the regeneration may be required to be carried out on the run (out on the open road).

That's nothing like the standard Dpf. So I don't think it would do the job.

If I can get a part number I'll definitely explore the ebay route rather than paying dealership prices...

Pm me your email, chassis number and engine code, I'll look it up for you.

I've just had the DPF light come on with my 2010 Tiguan with 50k on the clock. I've taken it for a run down the freeway at ~2500rpm to try and clear it (read that in a UK VW forum) but to no avail.

I'm a bit pissed as I love my Volksies and did my research with respect to the diesel over the petrol, but this problem didn't show up for me.

Being a n00b with this plugging in computer to cars stuff I'm not sure where I'm at.... but am I correct in thinking that a regen is effectively a temporary fix? Do we pay the ~$500 to get a few months of joy only to be stung with ~$3000 for a replacement DPF later down the track? Do we regen and just sell the thing? The DPF seems to be such a crock!?

Cheers!

Could be something simple like a DPF pressure differential sensor. Having said that, any DPF-related faults need to be diagnosed and repaired ASAP. Prolonged driving with a DPF-related fault present, may damage the DPF.

hi,
Definately get the dealership to check the pressure sensors. They have a history of failure in aus, but make sure if it is and they replace it that you argue to have the dpf replaced as its the most common form of dpf failure , ie caused by pressure sensor failures. Even if its able to be regen'd now, make it noted on the service records about the sensor in case you have further issues.

First up, if you ever need to replace a DPF, definately look at ebay UK and europe, I have seen MKV GT TDI ones for $700. You could have the long tailpipe removed to drop shipping costs, you just want the cannister and can weld on your old tailpipe.

I will have replacement cores available before too long, both standard and high flow, allowing a potentially legal "DPF delete" tune ( where you turn the regen operation off but it still removes most of the soot passively ). Removing the DPF entirely is a HUGE fine if caught, especially for tuners, so I won't do it I'm afraid.

That said, if there was no option, then Custom Code still have the only proven delete tune period. I don't care what anyone else claims, even the brand I represent. Only custom code have spent the time to work it out properly, everyone else is using a third party buy in, and I've yet to see one that works properly long term, and I know diesels.

As pointed out, the differential pressure sensor is notorious for playing up, and there is a revised part now, mine played up and I put the new sensor on, being a new part number. VW sells truckloads of them apparently.

The DPF is doing automatic regens when it reaches 40% blockage. You are usually unaware of this apart from the car idling at 1000rpm at times, and it feels a bit "rougher" to drive as boost presures are more aggressive to counter the mostly closed inlet flap during regen.

If the car fails to regen at 40% for whatever reason, usually a number of short trips beyond this point, it continues to fill up till it hits 60% at which point it will put up a warning on the dash "follow instructions" flash the coil light, and show the dpf symbol as it forces a regen. I've taken my car to this point many a time during experimentation, and it easily gets back down to "zero". So at this stage the DPF is a long way from cactus.

If this level fails, and for whatever reason it reaches 80%, the car goes into limp, and you HAVE to visit the dealer for a idle / forced regen, it is dangerous to try a Vag Com induced regen on the car as it *may* catch fire given the blockage and massive regen temps and time. Unlikely though.

As Gav has pointed out, it is unlikely for a DPF to go before 100k, more likely to reach 150k, but if the dealer cannot regen it, and it reaches a certain gram weight of soot ( 40g off the top of my head ) then it is indeed dead, and you need a new core.

Largely the DPF works well, and keeping the car on boost, running a Provent to reduce oil ash, and making sure your car gets some 80kph plus drives for a good 10 mins or so here and there all aid it's lifespan.

I am very aware some people choose to delete it, thing is the car becomes a horrible soot blower, and even the young bucks that have done it are now talking to me about the possible "high flow never clog no regen" DPF core, as that much soot is simply embarassing these days. Once I can prove it works on my car, I will look into the legality of having it produced, and go from there. It's a big task, but one that I believe to be possible. It won't happen in the short term though!!!
