C'mon.... I refuse to believe that those working on your vehicle know anything about what they are doing.....

Or the driver is short tripping the car and it can't regen. People that short trip and have little knowledge of the car usually suffer this fate at some point.

They have been talking to Volkswagen and this is what they were recommending. My last TDI, which I drove for 200,000 miles, never had any of these issues. I do some short drives, but generally between 15 and 30 minutes to school or work.

It would still go into active regen and throw all sorts of codes meaning that he would take it back in for warranty.... it's nearly impossible to replace a DPF and ensure the system works properly only to have it fill up again in 3k....

Something stinks here.... other than @KellyGB's exhaust that is!

You said that your last TDI was an 06. Not the same engine or emissions crap. You really can't relate your experience of that one to this one.

15 to 30 minutes is short tripping it in my opinion. A regen can take that long, after the car gets up to temp completely. I would say you could cure most if not all of your issues with this if you monitored your dpf soot status and went for a drive now and then when it was full to let it regen properly each time. About every 200+/- miles or so. Regens for me typically run 10 to 15 minutes. I monitor mine with an app and a BT dongle to the OBDII port on the car. VAGDPF is the app I use on my phone and I can see exactly what is going on. When it needs a regen I drive it around until it is done. There are multiple tools out there that can alert you when one is due or starting. If you keep the car I would invest in something like that to help.

Yes the 2006 did not have any dpf or such on board. Just a cat IIRC.

Sounds good.
Those of us who drive a lot (not me anymore) will have to decide what to do with the car or DPF/EGR once the warranty expires. It might make sense to either sell the car, or put the (relatively new) DPF and EGR on the shelf, or maybe just block off the EGR, and keep driving with a cracked DPF. It probably depends on the DMV inspections in your state.
I perminantly fixed my emissions at 6 months of ownership. Purchased at 91,500 1-5-2020. Current miles 147326. Haven't had an issue.

That makes sense. For regen, you warm the car and then drive until it is done, 10-15 minutes? I guess I didn't realize that short tripping was a thing since it never came up with my previous TDIs, although I understand they did not have a dpf.

A proper operating system will go all ape$h1t and throw all sorts of CELs long before you can fill the DPF to the point that it needs replacing.

If the owner reacts to those signs accordingly, there's all sorts of initiated regens, driving regens, service regens that can be performed..... If other components have also failed, whoever is fixing the issues isn't doing it correctly and the system is not functioning as it should .

We are not getting the full story here, as it doesn't compute based on my limited knowledge of how the system works.

That makes sense. The 15 months I drove the car, I had no issues at all... Something definitely seems off... I appreciate the input...
Thanks everyone!

Only once since I have owned by 2014 Q5 did the DPF warning symbol light up. I took it for a vigorous drive on the freeway at night (I drove it like a raped ape) to force a regen and all has been good so far and that was about 6 months ago.

Hey fellow TDI people. Hope your vehicles are treating you nice. I am having signs of trouble with my beloved shamu. White smoke billows from under my car and from the engine compartment while regenerations happen. It does not smoke any other time thou. The car seems to run fine, no check engine, dpf, glow plug lights of any sort on the dash. No limp mode, full use of rpm band. This has happened twice so far and the smoke is concerning enough that I am in the process with the dealer (under emissions warranty) to figure out what is wrong (appt Nov 1st). I do have soot in my tail pipe and from reading the other posts/topics points to cracked/failed dpf. Will update on what the dealer says, but in the mean time have any of you had this sort of failure mode happen to your tdi where it smokes NOT from the tail pipe but from under your car and engine hood while regenerating ? I think ive read of something of a fifth injector needed for the regen system. Maybe that's damaged and its causing the smoke? Maybe theres a pin hole leak in the dpf to the outside? but then I feel I would see smoke all the time. For reference the smoke smells like burning motor oil and plastic. maybe shoulda listened to oldman scotty k about the celicas haha.
Emissions fix at 48,000k
Miles driven post fix 27,490k
Mainly highways 80-85mph
Always (for the most part) let regens finish.

Definitely a dealer problem if you are under the Extended Emissions warranty. You should never have smoke billowing from under the car at any time. Or have soot in the exhaust either. Both should be covered by the warranty but you will probably need a check engine light or set a code for them to even do anything. Which might mean waiting until it sets a code. In the meantime, read up on the warranty so you know exactly what it covers and when. Hard to talk to them if you don't educate yourself first.
